aget - A small and performant HTTP/HTTPS/Gemini download tool
Usage:
> aget ?
URL/A,TO,BUFSIZE/K/N,TIMEOUTSECONDS/K/N,TOSTDOUT/S,ONLYPROGRESS/S,QUIET/S:
URL: The URL to download.
TO: Optional destination path. The default is to download to
the current directory to the URL file name. If a drive or
directory is specified, it will download to the URL file
name. If a complete path with file name is specified, it
will download to that.
BUFSIZE: Total buffer size in Bytes. This will be rounded to a size
which makes sense for writing to a file system.
TIMEOUTSECONDS: How many seconds to wait until connection times out. The
default is whatever the connect timeout is in the TCP/IP
stack uses.
TOSTDOUT: Print the downloaded file to the standard output instead of
downloading it to disk.
ONLYPROGRESS: Only show the progress bar during download.
QUIET: Be completely quiet, except if an error is encountered.
Example:
1> aget https://uhc.a1k.org/UHCTools.lha
Buffer size: 128kB
Connected to uhc.a1k.org:443
TLS/SSL connection using 'TLS_CHACHA20_POLY1305_SHA256'
Sent GET request!
Server response: 200 OK
Receiving file: 0% - [oooooooooooooooooooooooooooooooo] - 100% (39.15kB)
39.15kB received in 1.22s - 31.93kB/s
Additional usage details:
- A HTTP proxy can be used by setting the ENV-variable http_proxy to the URL
of the proxy.
- Using aget for HTTPS or Gemini requires AmiSSL 4+.
Relevant info:
It uses double buffering and asynchronous writes - downloads from the
network to one buffer at the same time as it writes the other buffer to disk.
This more or less removes the effect seek times and slow disks has on the
download speed (as long as the disk is at least as fast as the network).
This will be most effective if you have a real DMA disk controller, as then
the disk writes taking place at the same time as the network download will
steal a minimum of CPU time from the TCP/IP stack.
