Basically, if you know the number of the line in the history buffer, you can use !number to get to it. ! notation can get pretty deep really quickly. There's !-number (go back in the history number entries), !pattern (find the last command in the history buffer matching command). small typo !! - repeat previous (most-recent) command !19 - repeat command 19 !-4 - repeat 4th-ago command (back up 4 from current, in history) !?pattern? - repeat most recent command containing pattern you can also suffix any of these with :p meaning print only, don't actually execute the command. so it'll display what the command WOULD be, if you're nervious about just going ahead on faith. :) !!:p !?find?:p also, to get just one argument from any command, try: !$ - last argument, previous command !-3:1 - first argument, three commands ago !?grep?:* - all arguments, from the most recent command containing 'grep' !:0 - argument zero of the previous command ( == command itself) so see if you can determine what this does: which update-alternatives ls -lF `!!` wc !$ -- DEBIAN NEWBIE TIP: How do you determine which network services are open (active)? Try nmap localhost or nmap your-network-ip-address. If you don't have nmap try apt-get install nmap. NOTE: this will scan a host for open ports -- it's poor manners to scan anybody without their knowledge or consent. (Some folks have made it illegal, I think, so watch out!) ...from [EMAIL PROTECTED]
