Example--Diagnosing and Correcting Search Path Problems

This example shows that the OpenWindows executable is not in any of the directories in the search path using the which command.

venus% openwin
Command not found
venus% echo $PATH
no openwin in . /home/ignatz /sbin /usr/sbin /usr/bin /etc 
/home/ignatz/bin /bin /home/bin /usr/etc
venus% vi ~.cshrc
(Add appropriate command directory to the search path)
venus% source .cshrc
venus% openwin

If you cannot find a command, look at the man page for its directory path. For example, if you cannot find the lpsched command (the lp printer daemon), lpsched(1M) tells you the path is /usr/lib/lp/lpsched.
