#+title: Computer Notes
These are the notes I gathered my whole life so far about linux.


  - 1970  - Unix released by Ken Thompson and Dennis Ritchie at AT&T
  - 1977  - BSD released and got into lawsuit by AT&T since it contains unix code
  - 1983  - GNU project started by Richard Stallman to create Free unix-like os and protect it with GPL License
  - 1991  - A personal/hobby kernel project "Linux" started by Finnish Student named Linus Torvalds



      Redhat lives with a symbiotic relationship between centos and fedora or call it a love triangle if you will.
      While these compliment each other but these three kinda compete with each other for users attention.

      Redhat (RHEL):    -- A Serious Linux for serious business.
                                       -- Its free as in Speech NOT "free as in beer". 


	- Free and Open Source
	- Highly Secure
	- More stable and High Performance
	- Less Vulnerable to Malwares and Viruses
	- Frequently Updated and in Development
	- No drivers problem
	- Present in almost types of devices


  -  Can Difficult for beginners to use
  -  Need more knowledge seeker mentality than consumeristic to work with it.



  1. Everything is a File
  2. Small, Single-purpose programs
  3. Ability to chain programs together to perform complex tasks
  4. Avoid captive user interface
  5. Configuration data stored in a text file

  - /lib	shared library files
  - /media	directory for external devices mount points

  - /root	home directory for root user
  - /sbin	executable binary files used for system administration
  - /tmp	directory to store temporary files by system applications and users
  - /usr	contains executables, libraries, man files, documentations, etc

  *The features that most package management systems provide are:*

  - Package downloading
  - Dependency resolution
  - A standard binary package format
  - Common installation and configuration locations
  - Additional system-related configuration and functionality
  - Quality control

-- _for redhat based distros_ --
  - rpm                 =               RPM Package manager (RPM)
    Red hat's default package manager 
  - yum                 =               YellowDogModifier 
  - dnf                   =               A powerful package manager for redhat and fedora based systems
    DNF stands for Dandified YUM. A robust and fully functional, next generation package manager for RPM-based distros. Nothing could compete it in redhat universe. It can do all the things that yum should be better at doing like installing, updating, and removing packages alongside with smartly resolving dependancies during installation or removing of packages. 

    It is the default package manager of Fedora 22, CentOS8, and RHEL8. DNF is the next-generation version of YUM and intended to be the replacement for YUM in RPM-based systems. It is powerful and has robust features than you’ll find in yum. DNF makes it easy to maintain groups of packages and capable of automatically resolving dependency.

    *Whats the difference between DNF and YUM.*
    Due to many long-standing unresolved issues still remained in YUM it has to be replaced by DNF. These problems include poor performance, excessive memory usage, slowdown for dependany resolution.

    DNF uses "libsolv" for dependancy resolution, developed and maintained by SUSE to improve performance. 
    It was written mostly in python, and it has its own way of coping with dependency resolution.

    Its API is not fully documented, and its extension system only allows Python plugins.
     
    Yum is a front-end tool for rpm that manages dependencies and repositories and then uses RPM to install, download and remove packages.

    *Why using DNF instead of yum?*

    There were ultimately three major reasons why Yum was forked into DNF. These reasons were long-standing and serious enough that Yum simply had to go. The reasons were:

    1. An undocumented API: This meant more work for developers. In order for developers to do what they needed, it was often necessary to browse through the Yum codebase just to be able to write a call. This meant development was very slow.

    2. Python 3: CentOS/RHEL8 was about to make the shift to Python 3 and Yum wouldn’t survive this change, whereas DNF can run using either Python 2 or 3.

    3. dependency solving algorithm: This has been an Achilles heel of the Centos package manager for a long time. DNF uses a state-of-the-art satisfiability (SAT), -based dependency solver. This is the same type of dependency solver used in SUSE’s and openSUSE’s Zypper.

    To put it simply, yum was outdated and couldn’t stand up to the rigors of the modern CentOS 8 distribution. You can visit the packages available in Eldernode to purchase a CentOS VPS server.

    *DNF command Benefits*

    You have to look at this from two different perspectives: The end-user and the developer. If you’re an end-user, the switch from Yum to DNF means one very simple thing: a more reliable experience. Where this reliability comes in is DNFs superior dependency solving.

   It will now be a very rare occasion that you go to install a package and the system cannot resolve a dependency. The system is simply smarter.

   End-users will also see much less memory usage during package installation. Installations and upgrades will also go much faster. That last bit should be of special importance. Running upgrades with the Yum tool was starting to grow unacceptably slow.

   If you’re a developer, the shift to DNF means you’ll be able to work much more efficiently and reliably. All exposed APIs are documented. Another plus for developers is that C will be implement. The developers have created hawkeye and librepo .

   They will also be releasing even more C-based APIs in the future. Considering C is still such a widely-used language. So this should be a welcome change to developers.

To ignore a package from being upgraded, you need to add it to IgnorePkg or members of IgnoreGroup in the pacman.conf file.

Say for example, to ignore vlc from being upgraded while updating your Arch Linux you need to do the following.

Edit pacman.conf file:

`$ sudo vi /etc/pacman.conf`
Add the line – “IgnorePkg = vlc” as shown below.

Pacman won't upgrade packages listed in IgnorePkg and members of IgnoreGroup

#IgnorePkg =

IgnorePkg = vlc

#IgnoreGroup =

Save and close the file. To ignore a group of packages, you need to add IgnoreGroup = plasma-desktop, for example.

Whenever you try to update vlc, you will see a warning message like below.

`$ sudo pacman -S vlc`
Sample output:

:: vlc is in IgnorePkg/IgnoreGroup. Install anyway? [Y/n]

To remove this, simply remove or comment out the line IgnorePkg = vlc by adding a # sign in-front of it.

Now, again run the following command to update Vlc:

`$ sudo pacman -S vlc`

Sample output

dependencies...

looking for conflicting packages...

Packages (1) vlc-2.2.4

Total Installed Size: 10.7 MiB

Net Upgrade Size: 2.15 MiB

(1/1) checking available disk space [######################] 100%

:: Processing package changes...

(1/1) upgrading vlc [######################] 100%


As you see in the above output, Vlc has been upgraded to the latest version.

The above method will permanently stop the specified package from being upgraded until you remove it from the ignore list.

To do this temporarily, you can simply run:

`$ sudo pacman -Syu --ignore=vlc`
This command will skip vlc package from being updated. Similarly, to skip a package group, just run:

`$ sudo pacman -Syu --ignoregroup=plasma-desktop`


When you update packages to newer version older version of packages are still there.
SO if you want to clear out all these older packages from caches do this.
	`df -h` 	- to check disk size
	`pacman -Sc`	- To clear caches


it also clear the caches of your installed packages which are needed when
package update doesnt work and you have to downgrade until the issue is fixed.
Thats not a big disaster because you can easily downgrade a package using Arch repo.
But be careful before you use this. And DO NOT use this oftenly. ONLY once in a year or so.
Source: https://endeavouros.com/docs/pacman/paccache/



When you install a package with Pacman, it stores all downloaded packages
in `/var/caches/pacman/pkg` folder. But pacman didnt remove old and uninstalled
packages automatically by default so after a while the caches size will take
upto the substantial amount of your HDD or SDD.

Fortunately with pacman's built in funtion you can easily clear your caches
with this command `sudo pacman -Sc` but the the problem with this method is
it also clear the caches of your installed packages which are needed when
package update doesnt work and you have to downgrade until the issue is fixed.
Thats not a big disaster because you can easily downgrade a package using Arch repo.

=ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac output.mp4=

Here, we assume that the video file does not contain any audio stream yet, and that you want to have the same output format (here, MP4) as the input format.

If your audio or video stream is longer, you can add the -shortest option so that ffmpeg will stop encoding once one file ends.


If your output container can handle (almost) any codec – like MKV – then you can simply copy both audio and video streams:

=ffmpeg -i video.mp4 -i audio.wav -c copy output.mkv=


If your input video already contains audio, and you want to replace it, you need to tell ffmpeg which audio stream to take:

=ffmpeg -i video.mp4 -i audio.wav -c:v copy -c:a aac -map 0:v:0 -map 1:a:0 output.mp4=

The -map option makes ffmpeg only use the first video stream from the first input and the first audio stream from the second input for the output file.




=ffmpeg -i Video001.mp4 -i Audio001.mp3 -af afade=t=in:st=0:d=3,afade=t=out:st=47:d=4 -c:v copy -c:a aac -shortest Output.mp4=

In my case above the video was of length 51 so I chose Fade In of length 3 [Sec] and Fade Out* of ~4 [Sec]. Since fading is applied by a filter it required transcoding of the audio. In the case above I chose aac encoding.

  There are two ways to do it. (well, Probably more who knows? ¯\_(ツ)_/¯ )

  *First Using montage command*
   ImageMagick ships with the montage utility. Montage will append each image side-by-side allowing you to adjust spacing between each image (-geometry), and the general layout (-tile).
  =montage [0-4].png -tile 2x1 -geometry +0+0 out.png=

  *Second using Convert commnad*
   ImageMagick has command line tool named 'convert' to merge images horizontally, or for other purpose. i have tried this command and working perfectly on your case:
   To join images horizontally:
   =convert +append *.png out.png= 

   To stack images vertically:
   =convert -append *.png out.png=

   *Use -resize if the images don't have the same width/height*
   You can fix the height for all of them with the -resize option, e.g. to fix a 500 pixel height on two images joined horizontally:
   =convert +append image_1.png image_2.png -resize x500 new_image_conbined.png=
   
   Or for vertical joins, you would want to set a fixed width instead:
   =convert -append image_1.png image_2.png -resize 500x new_image_conbined.png=

Book Name: Python the hard way
Printing
- can be print with quotes double or single, inside of each others.
formatting
- =print(f"my hais is {color} color.")=


[This setup is based on Luke Smith's voidrice config but i made some changes to make it work for me]

Step 1 : Install

`sudo pacman -S ncmpcpp`
or
`yay -s ncmpcpp`

Step 2 : Configure

- create config files:
  `nvim ~/.config/ncmpcpp/config`

- paste the content from here:


- Go to `~/.config/mpd` folder
  - create/edit config file
  - paste the content from here:
  *[[mpd/mpd.conf]]
    - Edit them according to your need like changing music directory and all.

- Inside `config/mpd` folder create these files and folder too
  - `mkdir playlists`
  - `touch mpd.conf mpd.db mpd.log mpd.pid mpdstate`

Step 3 : Initialize mpd and start ncmpcpp

- open terminal and follow instruction

  - kill mpd process
    `killall mpd`

  - start mpd
    `mpd`

  - start ncmpcpp
    `ncmpcpp`


Enjoy!


#notes

1. Git clone git.suckless.org/dwm

2. make -C /dwm

Look for X11NC and change values to /usr/include/X11
and usr/lib/X11

save it and compile it with sudo make clean install

4. goto /usr/share/xsessions/
and create a dwm.desktop file

and write these lines in it

[Desktop Entry]
Encoding=UTF-8
Name=dwm
Comment=dwm window manager
Exec=/usr/local/bin/dwm
Type=Application

save it and exit i3 to and launch dwm


To Patch Suckless utilities
patch -p1 < name of the patch.patch

if hunk error occur
  check .rej file copy/add + commented lines and remove - commented lines
  and paste into respected file and make neccessary changes to said file in patches website
  and make install


-----------------------------------------
- Install pass: `sudo pacman -S pass`

1. Know your drive
=sudo fdisk -l=

2. Flash it.
=sudo dd bs=4M if=/path/to/endeavouros-x86_64.iso of=/dev/sdX status=progress && sync=
-----------------------------------------------------------------------

- run =df= or =sudo fdisk -l= or =lsblk -l= to list devices
- know your device
unmount it
=sudo umount /dev/sdc1=
- format it
=sudo wipefs --all /dev/sdc=
- now partition it properly with =sudo cfdisk /dev/sdc=
[select msdos for usbs` and create partion as default if not found vfat option in type leave it as linux 83]
- then write filesystem and mount it
=sudo mkfs.vfat -n 'MYUSB' -I /dev/sdc1=
=sudo mkfs.fat -F32 /dev/sdc1=
[The first command will wipe entire data and restore every sector to zero and original so this process is also helpful when formating bootable usbs to normal usbs]

if nothing work to return your pendrive to normal there is one last thing you can do.
- Open Terminal, make sure device is unmounted and run this command
- =sudo dd if=/dev/zero of=/dev/sdc= (No need to add number)
- IT CAN TAKE MUCH TIME so wait for atleast 5 minute
- and then every thing is successful and message shows there is no space left in device then consider its normal
- now you can use above methods to create partition table and format it to vfat.
Thanks to this video It helped me to figure out.

# Usb Errors

wrong fs type, bad option, bad superblock on /dev/sdb1,

missing codepage or helper program, or other error


This will wope out the drive!
- =mkfs.ext4 /dev/sdc1=
- =fdisk -l= If you can see your drive thats good.
- =fsck /dev/sdc1 -y= repairing superblock


After a reboot, the boot process drops to the BusyBox shell and I end up at the Initramfs prompt:
`BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs)`

- Firstly, boot into a live CD or USB
- Find out your partition number by using
  =sudo fdisk -l|grep Linux|grep -Ev 'swap'=

- Then, list all superblocks by using the command:
  `sudo dumpe2fs /dev/sda2 | grep superblock`
  Replace "sda2" to your drive number

- Now, to check and repair a Linux file system using alternate superblock # 32768:
  =sudo fsck -b 32768 /dev/sda2 -y=
  The -y flag is used to skip all the Fix? questions and to answer them all with a yes automatically

- Now try mounting the partition:
=sudo mount /dev/sda2 /mnt=
Now, try to see if device is doing read and write correctly:
=cd /mnt mkdir test ls -l cp file /path/to/safe/location=
If you are able to perform the above commands, you have most probably fixed your error.
- *Now, restart you computer and you should be able to boot normally.*


# How to install Fonts on Linux
- create a directory "fonts" in ~/.local/share/fonts
  `mkdir ~/.local/share/fonts`
- copy fonts to this directory
  `cp -r *.ttf ~/.local/share/fonts`
- clear and regenerate font cache
  `fc-cache -f -v`
- verify the installation
  `fc-list | grep "Hack"
- Cleanup


To transfer Files Over ftp on Arch Linux!
#ftp #fixes #notestonubelikeme 

Are you on arch-linux?
Are frustrated like me wondering where is ftp in arch repos?
then look no more just install lftp

=sudo pacman -S lftp=

connect with your ftp server

=lftp admin@192.168.24.1:1234=

just like that you connected and 
free to use your ftp commands such as get and put to upload and download files over ftp

Here our target site is  http://www.phenomenamagazine.co.uk/back-issues/4571429617

1. Open Terminal
Type this command
grep -o "file/d/.*/view" <(curl -s http://www.phenomenamagazine.co.uk/back-issues/4571429617 http://www.phenomenamagazine.co.uk/)

Add awk, to print the middle part:
| awk -F/ '{print $3}'

2. This should print you all the wget commands which are going to be executed:
for id in $(grep -o "file/d/.*/view" <(curl -s http://www.phenomenamagazine.co.uk/back-issues/4571429617) | awk -F/ '{print $3}'); do echo wget -nc --content-disposition "https://drive.google.com/uc?id=$id&export=download"; done

3. Remove Echo Word and execute like this:
for id in $(grep -o "file/d/.*/view" <(curl -s http://www.phenomenamagazine.co.uk/back-issues/4571429617) | awk -F/ '{print $3}'); do wget -nc --content-disposition "https://drive.google.com/uc?id=$id&export=download"; done

Note: -nc flag won't override the existing one in case you rerun the command again

_Now you know how it works for more info type man figlet_

     cowsay -f eyes "hi"

type man cowsay for more info
See /usr/share/cowsay/cows for more templates

### For Regular User Terminal
 - Open Terminal
- Switch to root using su root command
- Type
    leafpad .bashrc
 (leafpad is name of text editor it may be differs for you t xed, gedit or nano instead)
- Once .bashrc file opened scroll down to the last line where you found #fi
- Add one more line after #fi line and add these lines:

    figlet anything
    cowsay -f eyes "anthing"

- Now save the files and open new terminal as root to see changes
### For Root Terminal:
- Open Terminal
- Switch to root using su root command
- leafpad /root/.bashrc (nano is name of text editor it may be differs for you try xed, gedit or leafpad instead)
- Once .bashrc file opened scroll down to the last line where you found #fi
- Add one more line by after #fi and add these lines:

     figlet anything
     cowsay -f eyes "anthing"

- Now save the files and open new terminal as root to see changes
- Done, Now every time you open root terminal you will see your banner.

# IN WINDOWS WE USE INBUILT DISKPART TOOL

- Open Command Prompt as Administrator
- Type `diskpart`
- list the disks `list disk`
- select your usb drive `select disk 1`
- clean the filesystem on disk `clean`
- create primary partitinon `create partition primary`
- make it active `active`
- select it `select partition 1`
- format it `format fs fat32`
- wait to complete formating
- Done! Now you can exit `exit`

Open a notepad and copy below text into it and save it as rip.bat file

@echo off

ren uha.dll uha.exe

uha.exe a -m3 -r -pf -o video.arc F:\location

ren uha.exe uha.dll


I think its useful for compressing huge files to incredible smaller size files.

Trick 1:
- Goto this location:

(for windows xp)
`C:/Documents and Settings/username/ApplicationData/IDM/DwnlData`

(for windows vista):
`C:/Users/username/AppData/Roaming/IDM/DwnlData`

- copy unfinished file to your pen drive
- Open the IDM
- Select the Unfinished file
- Goto `Tasks > Export > To IDM export file`
- Save it with any name in your pendrive
- Now Goto another computer IDM
- Goto `Tasks > Import > Import the exported file`
- Start Downloading the imported file
- Pause Downloading when it starts Receiving all the Partitions
- Now copy and replace the content of respective folders
- Now resume the Downloading and it will work for sure.



- Open `Options > Save To dialog (Options > Downloads)` for older versions and look what folder is set in Temporary directory field.
- Save this folder somewhere in order to use it later.
- Do the same for all categories download folders in order to save your completed downloads.
- At the same dialog look what folders use for default download directories for each category. save these folders as well if necessary.
- Export `HKEY_CURRENT_USER\Software\DownloadMana..` registry key and also save it.
- On another computer import registry key that you saved.
- Copy IDM temporary folder and all default download directories under the same path that they had on initial computer.
- Run IDM.]


1. First Install GRUB
 - `pacman -S grub os-prober efibootmgr` (later packages for efi systems and ability to dual boot)
 - `grub-install --target=i386-pc /dev/sda` for legacy bios
 - `grub-install --target=x86_64-efi --efi-directory=/boot --bootloader-id=GRUB` for UEFI Systems

2. Make config
 `grub-mkconfig -o /boot/grub/grub.cfg`

3. Install theme
 `pacman -S artix-grub-theme`

4. Select theme
 add this line `GRUB_THEME="/usr/share/grub/themes/artix/theme.txt` in `/etc/default/grub`

5. Then update grub with step 2. again.


Use Mouse with Keyboard

 To add mouse functionality to numpad keys
 add this line to `~/.xprofile` or `remaps` script from `~/.local/bin/`
 `setxkbmap -option keypad:pointerkeys &`

		 and

 this line to `/etc/X11/xorg.conf.d/00-keyboard.conf`
 add `Option "XkbOptions" "keypad:pointerkeys"`

		 and

 press `Ctrl+Shift+Numlock` to activate it.

Always remember links not work when not linked with full paths

example: when you are in a directory of a file of which you want to create a link in another directory
in this case
Do not do this: ln -s filename /home/user/.local/dir/linkname
neither this ln -s ./filename /home/user/local/dir/linkname

Instead do this
ln -s /home/user/dir/filename /home/user/local/dir/linkname
always include full path of both source and link files

put this link in urlbar of chromium based browsers
`brave://flags/#enable-force-dark`

and enable `Force Dark Mode for Web Contents` options

See the contents of ...

/var/lib/AccountsService/
/home/$USER/.face

    the 1st will have a desktop styled file
        the 2nd holds the image taken from a webcam in case you used that

	To change the 1st check the desktop file for the dir at Icon= and replace the file it points to (make sure yours is the same size). The second just requires you to move a file to it (probably in the same size and format).

	If you want to remove the picture altogether and default back to no profile picture, remove the property that says Icon=, or if you want one single command to do it for you:

	sed -i '/Icon/d' "/var/lib/AccountsService/$USER"



A file with the MDE file extension is a Compiled Access Add-in file used to store a Microsoft Access MDA file in binary format.

Advantages of MDE files include a compacted file size, VBA code that can run but can't be changed, and the ability to edit data and run reports while shielding the user from having full database access.

Other MDE files might be unrelated to MS Access and instead be add-in files used with the architectural design software ArchiCAD to extend the program's functionality

How to Open an MDE File

MDE files can be opened with Microsoft Access and probably some other database programs as well.

Tip: You can make an MDE file in Access through the Tools >> Database Utilities >> Make MDE File... menu option.

Microsoft Excel will import MDE files, but that data will then have to be saved in some other spreadsheet format like XLSX or CSV.

Graphisoft ArchiCAD's add-in files that have the .MDE file extension can be opened with that program.

Note: If you find that an application on your PC does try to open the MDE file but it's the wrong application or if you would rather have another installed program open MDE files, see our How to Change the Default Program for a Specific File Extension guide for making that change in Windows.

How to Convert an MDE File

Read the instructions on Granite Consultingand Pruittfamily.com for some information on converting an MDE file to MDB.

Once the information in the MDE file is in the MDB format, you can convert the MDB file to ACCDB or ACCDE using Microsoft Access.

A tool like MDE Compiler should be able to convert your MDE file to EXE to create a standalone program.

Still Can't Open Your File?

If the programs above aren't working to open your MDE file, it's possible that you're misreading the file extension and you don't actually have an MDE file. 

For example, an Amiga MED Sound file and RSView Development Project file both use the MED file extension which is really similar to MDE but not the same.


Even though they look like they might be related to Microsoft Access or ArchiCAD, they instead open with ModPlug Player and RSView, respectively. 

The same is true for other file extensions that might sound or look like "MDE," like MME which belongs to the Multi-Purpose Internet Mail format, or MDD which might be a Point Oven Deformation Data file or an MDict Resource file.


First the signals described in the original POSIX.1-1990 standard.

   Signal     Value     Action   Comment
   ──────────────────────────────────────────────────────────────────────
   SIGHUP        1       Term    Hangup detected on controlling terminal
                                 or death of controlling process
   SIGINT        2       Term    Interrupt from keyboard
   SIGQUIT       3       Core    Quit from keyboard
   SIGILL        4       Core    Illegal Instruction
   SIGABRT       6       Core    Abort signal from abort(3)
   SIGFPE        8       Core    Floating point exception
   SIGKILL       9       Term    Kill signal
   SIGSEGV      11       Core    Invalid memory reference
   SIGPIPE      13       Term    Broken pipe: write to pipe with no
                                 readers
   SIGALRM      14       Term    Timer signal from alarm(2)
   SIGTERM      15       Term    Termination signal
   SIGUSR1   30,10,16    Term    User-defined signal 1
   SIGUSR2   31,12,17    Term    User-defined signal 2
   SIGCHLD   20,17,18    Ign     Child stopped or terminated
   SIGCONT   19,18,25    Cont    Continue if stopped
   SIGSTOP   17,19,23    Stop    Stop process
   SIGTSTP   18,20,24    Stop    Stop typed at terminal
   SIGTTIN   21,21,26    Stop    Terminal input for background process
   SIGTTOU   22,22,27    Stop    Terminal output for background process

   The signals SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.

   Next  the  signals  not  in  the POSIX.1-1990 standard but described in
   SUSv2 and POSIX.1-2001.

   Signal       Value     Action   Comment
   ────────────────────────────────────────────────────────────────────
   SIGBUS      10,7,10     Core    Bus error (bad memory access)
   SIGPOLL                 Term    Pollable event (Sys V).
                                   Synonym for SIGIO
   SIGPROF     27,27,29    Term    Profiling timer expired
   SIGSYS      12,31,12    Core    Bad argument to routine (SVr4)
   SIGTRAP        5        Core    Trace/breakpoint trap
   SIGURG      16,23,21    Ign     Urgent condition on socket (4.2BSD)
   SIGVTALRM   26,26,28    Term    Virtual alarm clock (4.2BSD)
   SIGXCPU     24,24,30    Core    CPU time limit exceeded (4.2BSD)
   SIGXFSZ     25,25,31    Core    File size limit exceeded (4.2BSD)

   Up to and including Linux 2.2, the default behavior for  SIGSYS,  SIGX‐
   CPU,  SIGXFSZ,  and (on architectures other than SPARC and MIPS) SIGBUS
   was to terminate the process (without a core  dump).   (On  some  other
   UNIX systems the default action for SIGXCPU and SIGXFSZ is to terminate
   the  process  without  a  core  dump.)   Linux  2.4  conforms  to   the
   POSIX.1-2001  requirements  for  these signals, terminating the process
   with a core dump.

   Next various other signals.

   Signal       Value     Action   Comment
   ────────────────────────────────────────────────────────────────────
   SIGIOT         6        Core    IOT trap. A synonym for SIGABRT
   SIGEMT       7,-,7      Term
   SIGSTKFLT    -,16,-     Term    Stack fault on coprocessor (unused)
   SIGIO       23,29,22    Term    I/O now possible (4.2BSD)
   SIGCLD       -,-,18     Ign     A synonym for SIGCHLD
   SIGPWR      29,30,19    Term    Power failure (System V)
   SIGINFO      29,-,-             A synonym for SIGPWR
   SIGLOST      -,-,-      Term    File lock lost (unused)
   SIGWINCH    28,28,20    Ign     Window resize signal (4.3BSD, Sun)
   SIGUNUSED    -,31,-     Core    Synonymous with SIGSYS

   (Signal 29 is SIGINFO / SIGPWR on an alpha but SIGLOST on a sparc.)

   SIGEMT is not specified in POSIX.1-2001, but  nevertheless  appears on
   most  other UNIX systems, where its default action is typically to ter‐
   minate the process with a core dump.

   SIGPWR (which is not specified in POSIX.1-2001) is typically ignored by
   default on those other UNIX systems where it appears.

   SIGIO (which is not specified in POSIX.1-2001) is ignored by default on
   several other UNIX systems.

   Where defined, SIGUNUSED is synonymous with SIGSYS  on  most  architec‐
   tures.

Make your Internet Faster with this little Trick! (This IS NOT A JOKE I Am Serious!)

Cloudflare, a well-known Internet performance and security company, announced the launch of 1.1.1.1—world’s fastest and privacy-focused secure DNS service that not only speeds up your internet connection but also makes it harder for ISPs to track your web history.

Domain Name System (DNS) resolver, or recursive DNS server, is an essential part of the internet that matches up human-readable web addresses with their actual location on the internet, called IP addresses.

For example, when you try to open a website, say wikipedia.com, your DNS looks up for the IP address linked to this domain name and load the site.

Since the default DNS services provided by ISPs are often slow and insecure, most people rely on alternative DNS providers—such as OpenDNS (208.67.222.222), Comodo DNS (8.26.56.26) and Google (8.8.8.8), to speed up their Internet.

But if you use Cloudflare new 1.1.1.1 DNS service, your computer/smartphone/tablet will start resolving domain names within a blazing-fast speed of 14.8 milliseconds—that’s over 28% faster than others, like OpenDNS (20.6ms) and Google (34.7ms).

Even if you are visiting websites over HTTPS, DNS resolvers log every site you visit, making your ISP or 3rd-party DNS services know about everything you do on the Internet.

“That means, by default, your ISP, every wifi network you’ve connected to, and your mobile network provider have a list of every site you’ve visited while using them,” the company says.

However, Cloudflare has changed this game with its new free DNS service, which it claims, will be “the Internet’s fastest, privacy-first consumer DNS service,” promising to prevent ISPs from easily tracking your web browsing history.

Cloudflare public DNS resolvers, 1.1.1.1 and 1.0.0.1 (as alternate DNS server for redundancy), support both DNS-over-TLS and DNS-over-HTTPS to ensure maximum privacy.

The company has also promised not to sell users’ data, instead to wipe all logs of DNS queries within 24 hours. It’s also working with auditors at KPMG to examine its systems and guarantee it’s not actually collecting your data.

Visit https://1.1.1.1/ from any device to get started with the Internet's fastest, privacy-first DNS service.

TUTORIAL How to:
Here is how you can set up 1.1.1.1 DNS for your devices, just follow this link: http://www.ethicalhackx.com/make-internet-faster-1-1-1-1-privacy-dns-server/

Hi Linux experts,
 using cp I need to copy all files except softlinks is there a command for that?

Reply:
	`cp -p ls -l|grep ^'-r'|awk -F" " '{print $9}' direcotry/`

	`ls -l|grep ^'-r'|awk -F" " '{print $9}'`
	it's fetching only files which start with -r
		directory start with "d"
		soft link start with "l"
		file start with "-"
