Tip #605   Un-alias a command

I used to have 'em' as an alias for Emacs. One day, I wanted to edit a file and typed 'rm' instead of 'em', losing the file I had no backup of. So I set a common alias to keep me focused. 

alias rm='rm -i'


But sometimes this can be very annoying as you can imagine. By placing a backslash in front of a command, you "un-alias" it. This works for any alias you have set. 

\rm *.c


I still use the 'rm' alias, but switched to just 'e' for Emacs ;^)
