Shell script using Diff
Hello - I have a small diff script that checks 2 directories. It reports the difference in count such as wc -l, and also names the different files.

How should I get "ERROR: diff found . (host)" - when it actually finds a diff?


This is how I have written:

Code:
#!/bin/bash

            DIFF=$(diff -r /home/student/bin/dir1 /home/student/bin/dir2 | grep Only | wc -l)
            DIFF2=$(diff -r /home/student/bin/dir1 /home/student/bin/dir2 | grep Only)
                        echo "The file count difference between master folder and CE-B-CM\D folder is:
${DIFF}"
            
            
            echo "The names of the different files and their paths are:
${DIFF2}."

            echo "####################################################"
