Compare output of commands
To compare the output of two commands, you need to use file descriptors (fd) which can be done like this diff <(command1) <(command2)
$ diff -y <(find /data/scripts/old -type f -ianme "*.sh" -exec basename {} \; | sort) <(find /data/scripts/new -type -f -iname "*.sh" -exec basename {} \; | sort)
