Finding out if a script has been modified

28/08/2007, 14h28

Hello *,

I would like to find out if anyone has modified a script on one of the
Linux servers i administer. Is there a command that creates a sort of
hash, a sort of CRC number or equivalent of a shellscript?

(I know that these questions should be properly addressed with a
version control tool, but this isn't feasable in my situation.)

TIA,
Helma.

I think sum is what you are looking for - man sum. Although I don't
know how you would use this after the fact, if you don't have original
scripts/sums to compare against...

sum can be faked. Use md5sum. That uses a cryptograpic hash mechanism.
EXTREMLY hard to fake md5sum.
