MacOS – Set / Change $PATH Variable Command

To set or change the $PATH variable in macOS, you can modify the .bash_profile file in your home directory.

1. Open Terminal
2. Open the .bash_profile file:

$ nano ~/.bash_profile

1. To add a new directory to the $PATH, add the following line:

export PATH=$PATH:/path/to/new/directory

Replace /path/to/new/directory with the actual path to the directory you want to add. 4. To modify the existing $PATH, simply edit the line that sets the $PATH variable:

export PATH=$PATH:/path/to/directory1:/path/to/directory2

1. Save the changes and exit the editor.
2. Apply the changes by sourcing the .bash_profile file:

$ source ~/.bash_profile

Your new $PATH variable will be set and will persist across terminal sessions.
