Editing Linux 101 hacks (section)

=='''Hack 61. Substitute words from history commands'''==


When you are searching through history, you may want to execute a different command but use the same parameter from the command that you’ve just searched.


In the example below, the !!:$ next to the vi command gets the argument from the previous command to the current command.


# ls anaconda-ks.cfg anaconda-ks.cfg 

# vi !!:$ 

vi anaconda-ks.cfg


In the example below, the !^ next to the vi command gets the first argument from the previous command (i.e cp command) to the current command (i.e vi command).


# cp anaconda-ks.cfg anaconda-ks.cfg.bak anaconda-ks.cfg 
# vi !^ 

vi anaconda-ks.cfg
