We also make sure to correctly support usernames that contain spaces. For simplicity sed + regex has been replaced with shell parameter expansion, which works in both, bash and dash.

# oe-git-proxy is a simple tool to be via GIT_PROXY_COMMAND. It uses socat
|
|
# to make SOCKS5 or HTTPS proxy connections.
|
|
# It uses ALL_PROXY or all_proxy or http_proxy to determine the proxy server,
|
|
# protocol, and port.
|
|
# It uses NO_PROXY to skip using the proxy for a comma delimited list of
|
|
# hosts, host globs (*.example.com), IPs, or CIDR masks (192.168.1.0/24). It
|
|
# is known to work with both bash and dash shells.
|
|
#
|
|
# Example ALL_PROXY values:
|
|
# ALL_PROXY=socks://socks.example.com:1080
|
|
# ALL_PROXY=https://proxy.example.com:8080
