How to make aliases permanent?

To make aliases permanent, you need to add them to your shell's configuration file. Here’s how you can do it for different shells:

For Bash

1. Open your terminal.
2. Edit the .bashrc file in your home directory:

   nano ~/.bashrc

3. Add your alias at the end of the file. For example:

   alias ll='ls -la'

4. Save the file and exit the editor (in nano, you can do this by pressing CTRL + X, then Y, and Enter).
5. To apply the changes, run:

   source ~/.bashrc

For Zsh

1. Open your terminal.
2. Edit the .zshrc file in your home directory:

   nano ~/.zshrc

3. Add your alias at the end of the file. For example:

   alias ll='ls -la'

4. Save the file and exit the editor.
5. To apply the changes, run:

   source ~/.zshrc

After following these steps, your aliases will be available in every new terminal session.
