Exit code "1" on diff command despite getting output
By Joseph Russell •
user@mbp$ diff --suppress-common-lines -y file1.txt file2.txtSome output
user@mbp$ echo $?
1
user@mbp$I'm curious why it throws exit code 1 rather 0 if its giving me what I need?
I realize this is more of a shell in general question rather than ubuntu.

a quick reading of the diff man pages showed me that the exit codes are different than what I was thinking.
Exit code 1 = differences were found.
