I know Howard does a great job of coming up with command line tips for the meetings. But here is one I forgot that I remember seeing a long time ago that can actually be useful.

If you're a csh/tcsh/zsh user, you've seen the supposed feature that lets you display how many commands you've run in your prompt: set prompt="\! %" The \! (or %h or %! for tcsh) displays not really a current count of commands run, but the current history event number. Think of it in those terms, and you'll discover it becomes quite useful. For example, how many times have you typed some enormously long command line, only to have it fail because several other conditions weren't met? You spend the next several prompts typing various commands to get conditions set up just right, and then have to retype the entire long command. Or, if it hasn't scrolled off the screen yet, just type ! followed by the history event number displayed in the prompt for that big long command. It's that simple: prompt 23 % command -with some -very +long /argument/list command: Example command failed. prompt 24 % cd /to/correct/directory prompt 25 % rm certain.files prompt 26 % !23 command -with some -very +long /argument/list command: Example command succeeds. prompt 27 % You can even apply the standard csh modifiers to !<number>. For example, particularly useful is !<number>:p, which just prints the command typed on prompt <number> instead of executing it again: prompt 26 % !23:p command -with some -very +long /argument/list prompt 27 % !! command -with some -very +long /argument/list command: Example command succeeds. prompt 28 % -------------------------------------------------------------------------- To Subscribe: http://www.ugu.com/sui/ugu/show?tip.subscribe To Unsubscribe: http://www.ugu.com/sui/ugu/show?tip.unsubscribe To Submit A Tip: http://www.ugu.com/sui/ugu/show?tip.today ========================================================================== DISCLAIMER: All UNIX HOT TIPS ARE OWNED BY THE UNIX GURU UNIVERSE AND ARE NOT TO BE SOLD, PRINTED OR USED WITHOUT THE WRITTEN CONSENT OF THE UNIX GURU UNIVERSE.
