How to change PATH order?

To change the order of directories in your PATH environment variable, you can modify it in your shell configuration file. Here’s how to do it:

For Bash Users

1. Open your terminal.

2. Edit your .bashrc or .bash_profile file (usually located in your home directory):

   nano ~/.bashrc
   

   or

   nano ~/.bash_profile
   

3. Modify the PATH variable by adding or rearranging directories. For example, to add /usr/local/bin at the beginning:

   export PATH=/usr/local/bin:$PATH
   

4. Save the file and exit the editor (in nano, press CTRL + X, then Y, and Enter).

5. Apply the changes by running:

   source ~/.bashrc
   

   or

   source ~/.bash_profile
   

For Zsh Users

If you are using Zsh, you would typically modify the .zshrc file:

1. Open your terminal.

2. Edit your .zshrc file:

   nano ~/.zshrc
   

3. Modify the PATH variable similarly:

   export PATH=/usr/local/bin:$PATH
   

4. Save and exit, then apply the changes:

   source ~/.zshrc
   

Verifying Changes

To verify that your PATH has been updated, you can run:

echo $PATH

This will display the current order of directories in your PATH. Adjusting the order allows you to control which executables are found and executed first.
