Where are alias' stored in Ubuntu 10.04

Question

I'm using a command which I don't know where the information is stored.

alias nup='ps ax | grep "nginx"'

Where is this alias saved?

Answer 1

It depends upon your environment and configurations. For bash, I would generally put it in a .bashrc file that in a home directory.

Answer 2

In ubuntu alias get stored in the .bashrc file.

If you are typing alias update_linux='sudo apt-get update' in the terminal, then it will create an alias temporarily. It works until you close your terminal.

To add an alias permanently you can edit ~/.bashrc and add the alias to it:

gedit ~/.bashrc

and add alias at the end

alias update_linux='sudo apt-get update'

Don't forget to refresh the .bashrc configuration, by running:

source ~/.bashrc
