Using a text editor, open your .bashrc
file, which is typically found in your home directory.
vim ~/.bashrc
This file is loaded whenever a new bash instance is started and should included bash-specific commands, like aliases.
The anatomy of an alias is as follows:
alias alias_name="text to alias"
Here is a common example:
alias ll="ls -lha"
This means that whenever you type ll
, it will be as if you had typed ls -lha
.
It is basically a substitution, so if you have an alias set up like this: alias g="git"
. Then you can type g pull
, which will execute git pull
.
If you'd like to use your alias, you can either open a new bash shell, or source your .bashrc
file in your current shell using:
source ~/.bashrc
This basically executes everything in your .bashrc
file as if you had typed each command.
