Bash Tip 1
Often when operating on the commandline you may want to re-execute something with elevated privileges. There is a shorthand way to do this rather than either cutting and pasting or retyping the line.
[email protected]:~$ updatedb updatedb: can not open a temporary file for '/var/lib/mlocate/mlocate.db' [email protected]:~$ sudo !! sudo updatedb
The first updatedb command needs to be ran as root, initially I forgot the sudo so it couldn’t update the database. Running it again with !! meant that I didn’t have to retype the whole command… Obviously this is more impressive with longer lines…tags:
