sudo !!
Instant favorite
- AaronBBrown 14y agoI often alias `sudo` to `fucking` to help vent my frustrations $ rm -rf somedir rm: somedir/: Permission denied $ fucking !!
- prakashk 14y agoI have been known to use sudo when it is not appropriate to use the f-word ;)
- amboar 14y agoAlong the lines of magic shell variables, there's also '!$', which selects the last argument of the previous command. Often I'm looking at different aspects of the same file: $ file foo $ ls -lh !$ $ vim !$
- mixedbit 14y agoI don't find this one useful. [up-arrow] automatically inserts the last command, which gives a generic mechanism to correct the command and it requires no more typing than !!: [up-arrow][control-a]sudo [enter]
