Cheers. It is worth the trouble to learn what the shell does first before trying to understand the other commands. The shell parses every command line you type and performs variable substition, i/o redirection, and wild-card filename expansion before the other programs even start, thus you won't find them discussed in all those other man pages. -- Les Mikesell les@xxxxxxxxxxxxxxxx
