Test it by running echo $PATH again in the Terminal. So here I have copied my existing path and added the new location on the end, colon separate the paths. You can add extra locations to your path, in the myscript.sh example above it’s location /Users/yourusername/bin/ which is not in the default path, you can add it in Terminal like so: PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin :/Users/yourusername/bin/ These directories are not visible by default in the filing system but you can make them visible. /Library/Apple/usr/bin (If you have Xcode).So this is stating that you can run Unix style applications or commands located in 5 or 6 default locations of a certain path in the filing system: You can find out whats in your path by launching Terminal in Applications/Utilities and entering: echo $PATHĪnd the result should be like this.(the last one when you have Xcode) /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin Your shell path is a bunch of absolute paths of the filing system separated by colons : You can just type the command, regardless of where you are in the filing system: myscript.sh So instead of running something like this, with a path to the command or script: /Users/yourusername/bin/myscript.sh

The shell path for a user in macOS is a set of paths in the filing system whereby the user has permissions to use certain applications, commands and programs without the need to specify the full path to that command or program in the Terminal.
