Ubuntu – How to remove an alias

aliascommand line

I want to remove gs alias from my PC. When I type gs it will open GhostScript. But I checked everywhere in the home directory .alias .bash_aliases .bashrc

I also overwrite the gs with my custom alias.

I can't remove it. And I also type alias in terminal, in the list I couldn't find it.

Please I want to remove it…

alias apacheres='/etc/init.d/apache2 restart'

Command-Line – Why Alias in /etc/bash.bashrc Not Apply to Sudo

sudo will ignore any aliased commands from .bashrc.

You can work around this by creating an alias for sudo too --> alias sudo='sudo '

You need the space after sudo, since man tells us:

If the last character of the alias value is a blank, then the next command word following the alias is also checked for alias expansion.
