This is actually the mapping of permissions your file has. To begin with, we have a sequence of ten dashes and letters that may seem meaningless at first. We see the same file(s), but with plenty of information before it/them. This is the result when we type ls -l and press Enter: By adding the flag -l to it, it provides you with more information on the files in the directory. What it does is list all the visible files in the directory you are at the moment. In order to get some more information about your file, we will use the command that lists the files in a directory: ls.Īfter typing ls and pressing Enter, this is what we get in the command line: Then we'll move on to discovering how to change them.

How come I don’t have permission to run a script I wrote myself seconds ago? sample.sh and press Enter to see your script in action and…but what is this message telling me?

You can then write whatever you want in it using the file editor of your choice. If you ever try to create, for instance, a text file, all you have to do is type touch filename.txt, press Enter, and the file is created for you in the directory you are in.
