[olug] Unix Tip: SAYING PUT AND EXECUTING ELSEWHERE

[Sam Tetherow]

'pushd /dir' and 'popd' are the commands I think you are looking for.

As for the person who didn't understand the need of (cd /dir; 
somecommand), it is really nice for cases where you want to execute a 
command on the local directory without actually being there, for 
instance running a perl script that uses local modules (relative to the 
executable) or anything else that uses the local directory for the 
environement such as .conf files).  In the stated example (cd /etc; ls) 
it doesn't seem all that useful, but (cd 
/some/really/long/path/to/get/to/files; ls) it starts to be evident 
since ls /etc shows all files as /etc/hosts /etc/init.d etc.
