Try "fc -l" (thats dash ell) no quotes shows a tail of whats in .bash_history I think Or - if you know the command's number in the history sequence "fc {$line_no}" Brings Previous command comes up in your default editor Default here (Ubuntu Hardy) was set to the nano editor for some reason so i did FCEDIT=vi ; export FCEDIT NOW things are more better Jay Louis J Rouleau Semi-Old Man South Hadley --------------- Date: Wed, 12 Jan 2011 16:02:29 -0500 From: Jorden M <jrm8005@gmail.com> Subject: Re: [Wlug] Old man and LINUX To: Worcester Linux Users Group <wlug@mail.wlug.org> Message-ID: <AANLkTi=NDA=EenfiOTAcnROVGEjfajmH93mwss5vj9XQ@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 On Wed, Jan 12, 2011 at 3:56 PM, Ken Jones <kjones@ziplink.net> wrote:

apropos, although that isn't always helpful. Google. There are also some sites that have commands listed categorically. ------------------------------ Message: 4 Date: Wed, 12 Jan 2011 19:00:25 -0500 From: "John Stoffel" <john@stoffel.org> Subject: Re: [Wlug] Old man and LINUX To: Worcester Linux Users Group <wlug@mail.wlug.org> Message-ID: <19758.16537.740475.105771@quad.stoffel.home> Content-Type: text/plain; charset=us-ascii

In this case, I just did 'man -k text' and the last things that popped up were 'zmore'. Plus a bunch of other system calls and library calls about text handling. Maybe pickup one of the linux for beginners books that O'Reilly puts out? Unix in a Nutshell, etc. That should help you find commands. Also, *any* text editor will let you read a text file, even if you don't want to edit it.

If you want to see more than one command at a time, open .bash_history in your home with a text editor, or, while you're still remembering it, do 'more .bash_history'. If you remember the command, but you can't recall what options you used with it, 'grep some-command .bash_history' can help. You can set the system to hold more commands, if you want. In debian, the default is to hold the last 500 commands. I don't recall what it is in other distros. Spiral-bound notebook is good, too. A couple of pages of your favorite commands and just about anything else will still be readable if the system crashes. Greg Avedissian On 01/12/2011 03:56 PM, Ken Jones wrote:

I usually use "history | grep $blah" when looking for a particular set of command line options... On machines where I don't intentionally disable history for security...
