I have written a wrapping script for wget that -using tsocks- makes it
connect through a socks proxy if the environment variable socks_proxy
is set.
I'm sharing it here as it may be of interest for a wider audience (or
should it
be included on git?)
Regards
#!/bin/bash
set -eu
# Allows to execute wget using a socks proxy if the environment variable
# socks_proxy is set.
#
# The socks_proxy variable shall have one of the forms:
# socks://username:password@host:port
# socks4://username:password@host:port
# socks5://username:password@host:port
# with username, password and port fields being optional
#
# As socksification applies to the whole process, domains defined in the
# no_proxy setting are not excluded.
