Reviewing Tar commands with one key

mvmoncayo · 10-14-2009, 08:37 PM

Hello,

I am trying to recall all tar commands that I have executed. Then I am trying to see them in turn by repeatedly pressing one key.

I would like to use either history command and/or an alias.

Thank you for any help.

1. In a shell session, perform your tar actions.

2. Press the up arrow key repeatedly until you get to the first tar command.

3. Press the down arrow key to review your commands as entered.

Alternative:

1. Perform your tar actions.

2. Examine your .bash_history file:

$ kwrite ~/.bash_history

The most recent commands are at the bottom -- the commands are listed in chronological order.

Is this a homework question? If so, what have you tried? There is a combination of commands using "history", two "greps" and "more" (or "less") that would probably do almost exactly what you want.

Another way to see what tar commands you've issued is to use the following command:

history | grep tar

That'll display all occurrences of the tar command that's stored in your shell's history.

I was trying to avoid using the up arrow key. Yes this was a homework question. I figured out what it wanted was for me to actually browse the history using in line command editing. First I set vi options by using set -o vi. then type /tar (to match the tar pattern) and [esc]. I then I can press n to go through the different tar commands. Thank you for all your help.
