you can see that the output becomes just the account names. This script could compare full files—heck, there's even a Linux command for the job—but you don't want to get false positives if users change their user names but otherwise leave their accounts intact. Further, I like clean, readable output, so that's what this will produce.

Here's the full script:

#!/bin/sh

# watch accounts - keep an eye on /etc/passwd,

# report if accounts change

secretcopy="$HOME/.watchdb"

tempfile="$HOME/.watchdb.new"

passwd="/etc/passwd"

compare=0 # by default, don't compare
