I don't know why you said either part of that. I didn't imply the latter and AFAIK the former is untrue (unless you ask the shell to send their output to a pipe); they "send" their command output (or variable value) to the shell as it does command and variable subsitution on your shell command line. Read "Command Substitution" in the "sh" manpage. I suppose there might be pipes involved in the shell innerds, but it's not useful to think about them. The output of the backticks, etc., becomes a part of the post-subsitution command input to the shell. The shell might or might not then send some of it to the screen, or run a command that outputs to the screen, depending upon what the command is. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
