tee to a file grep stdin I also recall a "multi-cat" or "multi-pipe" file, but can't seem to find it anywhere. Also: can this be done using a more complicated redirection in a standard shell? > > BTW - I have a partial solution and that's to pipe to a file and then do 2 > separate operations - cat the file to the screen and GREP the file to find > what I'm looking for. The problem is that I then see the output only after > the script has finished running - not **online**. If you chose to go that route, you could have used 'tail -f' and view it online. This may be useful if you have a script that sends *lots* of output to the terminal (espcially if it is a slow terminal), and you don't want the pipe's buffers to limit the script. -- Tzafrir Cohen mailto:[EMAIL PROTECTED] http://www.technion.ac.il/~tzafrir/ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
