Useful when you forget to use sudo for a command. "!!" grabs the last run command.
There are 3 alternatives - vote for the best!
\$ which python
\$ ll `!!`
lrwxrwxrwx 1 root root 9 2010-11-08 22:01 /usr/bin/python -> python2.6
Same as `sudo !!`. If you do not have permission to be sudo or sudo does not installed on your system, you can use this.
this command also can run the last command as root
what's more, sudo !-2 can run the second last command as root , and so on
I often forget to type sudo before a command that needs it. This is the quickest way to rerun the command prefixed by sudo.
If you can do better, submit your command here.
