How to Make a Shell Script Executable

Last updated 2013-01-08 - Send Feedback
Related: command line, how-to, software

A shell script is just a text file.

It might or might not have a filename extension like “.sh” or “.bash”.

To make it executable at the command line, its file flags must be changed to allow execution:

# Make the script 'verifyVolumes.sh' executable
diglloyd:MPG lloyd$ sudo chmod +x verifyVolumes.sh

Use this cautiously, do not apply willy-nilly, and only to trusted scripts.
