Repeat previous unix command

Hi all,

Is there a way to bring back the previous unix command without retyping?

I tried the "arror up" key, and it seems not working (sun solaris). What is the correct way?

Thanks!

Depends what shell you are using...
e.g. for Solaris
if you use /usr/bin/ksh:

# set -o vi (if not done yet as EDITOR=... in .profile...)
then its Esc+ k (backward...) j (Forward)
This works because you have a history file set...

In tcsh (and bash?) you can use

!! to execute the previous command again,
!-n to execute again the nth to last command
!foo to execute again the last command beginning with the string foo
!?foo to execute again the last command containing the string foo

Append
Code:
:p

to display rather than execute the command.

Repeat previous unix command

Thanks for your reply. I am using ksh.

In linux, if my last command is for example "ls -ltr |tail", I just hit the "arrow up " key to bring it (ls -ltr |tail) back on the command line and then verify it. This gives me the opportunity to display the command before executing it.

The command 'r' that vbe suggests is good, but it is executed before I even have the opportunity to dsplay it.

I need a command (or key stroke) in order to display and then repeat the execution without retyping the command. Any idea?

Thanks!
