Bash alias

Understanding alias

Aliases in Bash allow you to create shortcuts for long or frequently used commands. This makes it easier to execute complex commands with a simple keyword.

Creating Aliases

To create an alias, use the syntax alias name='command', where name is the shortcut you want to use, and command is the full command you want to run.

Example: Simple Alias - List

alias ll='ls -la'

In this example, ll lists all files in long format.

Example: Simple Alias - Git Status

alias gs='git status'

In this example, gs is a shortcut for git status.

Managing Aliases

To view all current aliases, use the alias command without arguments.

Example: Viewing Aliases

alias
alias ll='ls -l'
alias gs='git status'

To remove an alias, use unalias name.

Example: Removing an Alias

unalias gs

Creating Permanent Aliases

To make an alias permanent, add it to your ~/.bashrc or ~/.bash_profile file.

Example: Adding Permanent Alias - Open Editor

nano ~/.bashrc

Example: Adding Permanent Alias - Add Alias

alias ll='ls -la'

Example: Adding Permanent Alias - Save and Apply

source ~/.bashrc
