Hi Mark,
Here's an easy way of doing this:
find /etc/ -type f -exec md5sum {} \; > /tmp/my.md5.list
so then in /tmp/my.md5.list we have for example:
b4bed46e057e1e1843a24a7ebfb8ca0d /etc/csh.login
then I edit /etc/csh.login and run :
md5sum -c /tmp/my.md5.list | grep -v OK
and I see:
/etc/csh.login: FAILED
so it tells me something happened to this file.
But if you are looking for something to do file integrity checks there
are other options. I beleive that RH 7.3 comes with tripwire, you might
want to check that out.
Hope this helps,
Jeff
