Usage:
`basename $0` HOST PORT
Helper script to connect to a Git repository over the git:// protocol at host HOST and port PORT through a SOCKS proxy at $proxy ($from).
To use the proxy for all git:// traffic, set the core.gitproxy option to "git-proxy":
git config core.gitproxy "git-proxy"
To use the proxy only for some reporitories, use the syntax explained in git-config(1).
To configure which proxy to use, set an appropriate environment variable (see below) or socks.proxy option to the proxy address, for example "localhost:1080":
git config socks.proxy "localhost:1080"
The address of the proxy is read from (in order of priority):
- the GIT_SOCKS_PROXY environment variable;
- the SOCKS_PROXY or SOCKS5_PROXY environment variable;
- the ALL_PROXY environment variable (see curl(1));
- the socks.proxy git option;
- the default value: localhost:1080 .
