2019-10-24T00:16:47 #kisslinux <konimex> may be both
2019-10-24T00:17:59 #kisslinux <konimex> if ethernet usually you only need to enable the kernel module (either built-in or module can work), but wifi if you have proprietary firmware you'd need it to be compiled as module and modprobe it manually
2019-10-24T00:38:07 #kisslinux <absolem> I didnt compile loadable modules into the kernel.... fresh start it is.
2019-10-24T00:38:47 #kisslinux <absolem> Boy, do i feel dumb.
2019-10-24T00:40:08 #kisslinux <absolem> konimex: thank you for the pointers
2019-10-24T01:11:24 #kisslinux <nestman> to the shell masters : what's the difference between `${VAR##PATTERN}` and `${VAR#PATTERN}`?
2019-10-24T01:12:20 #kisslinux <nestman> i can't understand the man page
2019-10-24T01:13:37 #kisslinux <nestman> and i can't tell their differences because testing them returns the same values
2019-10-24T01:14:01 #kisslinux <nestman> same with `%` and `%%`
2019-10-24T02:32:18 #kisslinux <Crestwave> nestman: One symbol strips the shortest match, and two strips the longest match
2019-10-24T02:37:24 #kisslinux <nestman> Crestwave: Yes, that I can't understand. Can you provide some examples?
2019-10-24T02:38:53 #kisslinux <Crestwave> var=a/b/c; echo "${var%/*}"; echo "${var%%/*}"
2019-10-24T02:39:09 #kisslinux <Crestwave> var=asdf; echo "${var#*}"; echo "${var##*}"
2019-10-24T02:43:12 #kisslinux <nestman> why didn't "${var#*}" remove anything?
2019-10-24T02:43:16 #kisslinux <nestman> from asdf
2019-10-24T02:44:40 #kisslinux <Crestwave> Because the shortest match is nothing
2019-10-24T02:45:30 #kisslinux <Crestwave> * matches anything, including null
2019-10-24T02:46:24 #kisslinux <nestman> doesn't that mean it should match 'a'?
2019-10-24T02:46:31 #kisslinux <nestman> lol im so confused
2019-10-24T02:48:42 #kisslinux <Crestwave> No
2019-10-24T02:48:53 #kisslinux <Crestwave> Matching a would mean that the length of the match is 1
2019-10-24T02:49:04 #kisslinux <Crestwave> Matching null would make the length 0
2019-10-24T03:05:44 #kisslinux <nestman> so ${var#*} just means 'match nothing'?
2019-10-24T03:25:42 #kisslinux <Crestwave> In the end it always just evaluates to $var if that's what you're asking
2019-10-24T03:26:09 #kisslinux <Crestwave> That wasn't really a practical example but a demonstration of how it works, since I already gave a practical example for %
2019-10-24T03:55:59 #kisslinux <Crestwave> Local variables in POSIX sh: https://github.com/Crestwave/snippets/blob/master/local.sh
2019-10-24T07:44:13 #kisslinux <dylanaraps> > Welcome to GitHub Sponsors!
2019-10-24T07:44:31 #kisslinux <dylanaraps> Just need to setup Stripe now. :)
2019-10-24T07:46:31 #kisslinux <nestman> what is that?
2019-10-24T07:48:36 #kisslinux <dylanaraps> https://github.com/sponsors
2019-10-24T07:49:20 #kisslinux <dylanaraps> Basically Patreon but built into GitHub.
2019-10-24T13:51:07 #kisslinux <Crestwave> Aw, apparently my local variable hack relies on UB in POSIX
