as a quick demonstration on how globbing might run into the shell limits, try the following few commands. first, just try: $ ls /* the output of this command is not important, all that's important is that the shell had to expand the wildcarding to generate the command to run. if that worked, push it a bit harder: $ ls /*/* if that worked, a bit harder still: $ ls /*/*/* sooner or later, you'll hit the shell's limit as to just how large a command it can construct. rday p.s. note that you need to do this with an executable command like "ls". trying it with "echo" won't cause it to fail the same way as "echo" is a shell built-in. the actual limit is, i believe, in the exec() system call, but i'm willing to be corrected.
