Forget that your running as underprivileged? No need to retype the command:
> command_with_insufficient_permissions
Permission denied
sudo !!
The !! parameter repeats the previous command, thus no need to retype!

Want to show something on your machine to someone over the web? Don’t copy it or upload it somewhere, try this command (requires Python):
alias webshare='python -c "import SimpleHTTPServer;SimpleHTTPServer.test()"'
Just run “webshare” and the current directory and everything beneath it will be served from a new web server listening on port 8000. When you are finished, just hit control-c to close the webserver.

Hate having to remember all switches for each different unpacker? You can fix that!
Create a new file in /usr/bin/ called “extract” and paste the following code:
if [ -f $1 ] ; then case $1 in *.tar.bz2) tar xvjf $1 ;; *.tar.gz) tar xvzf $1 ;; *.bz2) bunzip2 $1 ;; *.rar) unrar x $1 ;; *.gz) gunzip $1 ;; *.tar) tar xvf $1 ;; *.tbz2) tar xvjf $1 ;; *.tgz) tar xvzf $1 ;; *.zip) unzip $1 ;; *.Z) uncompress $1 ;; *.7z) 7z x $1 ;; *) echo "'$1' cannot be extracted via >extract<" ;; esac else echo "'$1' is not a valid file" fi
be sure to chmod it to executable:
chmod +x /usr/bin/extract
This code will save you time by extracting almost any kind of archive by using the command:
extract my_awesome_archive.tar.gz
