Command Question

Quick question: Is there a command for repeating a command after executing the command (ex., the F3 key in Windows/DOS)? I haven't found this listed yet in my Linux books. Thanks!

up arrows will take you through the last commands in bash history.

the command
!!<return>

or you can cycle through your previous commands with the up arrow ...

the !!<return> you could program into your .inputrc file so that pressing F3 will cause the command to be issued.

should look something like
"\e[[C": previous-history

(I think)

Whatever suits your style the best, but here's a suggestion.

Code:

alias r='fc -e - '

Now r<Enter> would repeat the last command. r man<Enter> would bring up the last command that starts with man etc..

Apart from the one above, I also use..

Code:

set -o vi

Now you can navigate up/down/edit commands by presing ESC followed by j,k etc. Seach using ESC / etc.. Recommended only if you're a vi freak.
