bash-fu: You forgot to sudo
Wednesday, August 6th, 2008One of the more routine annoyances of a long day in the terminal is banging out some long command that happens to operate on a file your current user doesn’t have access to.
www@webserver:~$ rm -fr /usr/lib/python2.5/site-packages/buildbot/buildbot.png<br/><br/>
rm: cannot remove `/usr/lib/python2.5/site-packages/buildbot/buildbot.png': Permission denied
You declined to sudo the command because you you forgot, were feeling cautious, or were unaware of the permissions bits of the file(s) in question. Now you have to type it again, or switch gears and start up some cursor navigation to prepend your sudo.
Next time, as an easy to use alternative, try:
sudo !!
In bash, !! expands to the last run command. sudo !! sudo’s the last command. That was easy.
