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.
