How to create a permanent Bash alias on Linux/Unix

A bash alias is a shorthand way to reference a longer command. Aliases can be created temporarily, but they will be lost when you log out or restart your computer. To create a permanent bash alias on Linux or Unix, follow these steps:

1. Open your bash profile file: You can open your bash profile file using a text editor such as nano:

nano ~/.bash_profile

1. Create the alias: In the bash profile file, add the following line to create a permanent alias:

alias  =” ”

Replace with the name you want to give the alias, and with the full command you want the alias to reference. For example, to create an alias for the ls -la command, you would add the following line to your bash profile file:

alias ll=”ls -la”

1. Save and close the file: Once you have added the alias to the bash profile file, save the file and close the text editor.
2. Reload the bash profile: To use the new alias, you need to reload the bash profile. You can do this by running the following command:

source ~/.bash_profile

With these steps, you have created a permanent bash alias on Linux or Unix. The alias will be available in future sessions and will be automatically loaded every time you log in.
