![]() Remember, anything you can do in a terminal can be done with a shell script, and more! So all the commands you learned in our previous tutorials can be combined with the use of variables to automate some daily tasks. We hope that you now understand how variables work in shell scripts and that you can use them as well. You can also automate shell scripts using tools such as launchd or Apple Remote Desktop. Shell scripts are useful because you can combine many common tasks into one script, saving you time and possible errors when performing similar tasks over and over. This is a series of shell scripting tutorials and we will continue to write more articles on Linux shell scripting.
