Without setting aliases one by one... (I > use zsh.) Modify your shell config file to prepend /it/sw/gnutools/bin/ to PATH, then launch a new instance of the shell. I don't know the filename or appropriate syntax for that file for zsh, but with bash it would be ~/.bashrc (or /etc/profile, or any file invoked from either) and PATH=/it/sq/gnutools/bin:"$PATH" and it's exceedingly unlikely that zsh doesn't have comparable functionality, even if with different syntax. (Actually, I think the functionality may be specified by POSIX, though I can't swear to that without research.) -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. -- George Bernard Shaw
