Edit the last or previous command line in an editor then execute

fc [history-number]
If you would like to edit a previous command, which might be long and complicated, you can use the fc (I think it stands for fix command). Invoke fc alone will edit the last command using the default editor (specified by $FCEDIT, $EDITOR, or emacs, in that order). After you make the changes in the editor, save and exit to execute that command. The fc command is more flexible than what I have described. Please 'man bash' for more information.

To get the 3rd to last history item use a dash in front of the number: fc -3 To get a list of your history type: history then you can call one of the items by its number, like so: fc 666

@andreyevbr: fc is the same as fc $!
