I have to count the number of children directories of / that contain one or more home directories.
For instance, if john, emily and rick have their home directories in /home/john , /home/emily and /var/lib, the answer would be 2.
I assume I have to use a pipe with cut and grep, but I do not know exactly how.

I don't understand how /var/lib is different from /home/john or /home/emily in this regard. None of them are direct children of/; two of them contain/home, if that's what you're checking...?

Is the algorithm that "/home" contains two homedirs and /var contains one, so there are two unique top-level directories that contain home directories?

Are the paths to test predetermined or are you reading them from the/etc/passwdfile? And would 3 the answer to this list:/home/john , /home/emily , /varlib , /home/sally/Documents/Earth , /var/www?

You only need to find out where the home directory is set which you can get fromgetent passwd | awk - F : 'print $6'. It is most likely/homefor everyone unless it's been set as a different location for some of the users. Assuming that it is, you can usefind /home -maxdepth 1 -type d | awk 'END print $NR'and that will give you the total number. You can swap out/homeif it's elsewhere.
