- All right, let's have a look at the commands
that we have seen in this lesson.
It all started with chown, for change ownership.
We have seen chgrp, which is for changing group ownership.
You don't really need chgrp because you can use chown
to change user as well as group ownership at the same time.
We have seen chmod to change the permission mode.
Pretty important command.
It's really the command to manage permissions.
We have also seen diff, diff,
which allows you to show you differences between two files.
We have seen that in a context of set user ID,
where you want to use finds to find files
that have set user ID, and to compare files to one another
to see if anything has changed.
Unless it's about umask,
umask has been used for the default permissions.
That's all the commands that we have used in this lesson.
Let's go do the end of lesson lab.
