# How to Create a Bash Alias
1. Open your .bashrc file
Using a text editor, open your .bashrc file, which is typically found in your home directory.
> vim ~/.bashrc
### Why .bashrc?
This file is loaded whenever a new bash instance is started and should included bash-specific commands, like aliases.
2. Create the alias
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.
3. Reload your bashrc
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.
