^foo^bar replaces first instance of foo. If you want to replace multiple instances of a string, then you should use:
!!:s/foo/bar/g!!:s/foo/bar/gWon't work in bash. Instead, use:
!!:gs/foo/bar^foo^bar does not work in mksh
Works fine in bash!!
ex:
~$ lq -ltra
lq: command not found
~$ ^lq^ls
ls -ltra
Short notation for replaces all instances of foo with bar:
^foo^bar^:&I think it's safer to reload the command and edit it
!!:gs/^foo^barthis one is what i want
btw,i want to kown how to reload the command and then edit it in an easy way like in vim ...
