# Script that executes 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.
|
|
#
|
|
|
|
# Requisites: bash (version 3.2.3 or later), tsocks and wget
