Full Discussion: FileChecksum Monitoring
Operating Systems Linux FileChecksum Monitoring Post 303006534 by rbatte1 on Friday 3rd of November 2017 07:19:33 AM

Why not do an md5sum of all the files you are interested in to a single file? That way, just running md5sum -c checksums-file will do them all in one go. If you look at the file it creates, it will have the checksum and the examined filename in each record so you don't need to keep lots of separate single files and save you the worry of building/using an array.

For clarity, you can spread out your script if that helps, so saving the initial checksums:-
Code:
# However many files per line that makes sense to you, but nothing after the \ on each line

files_to_check="\
 /etc/passwd  /etc/shadow /security/access.conf \
 /etc/resolv.conf  /etc/sysconfig/network-scripts/* \
 /etc/fstab \
 /etc/httpd/httpd.conf \
 /anything/else/you/fancy \
"


md5sum $files_to_check > /var/lib/md5sums/critical.md5

Later you can just md5sum -c /var/lib/md5sums/critical.md5 and you get a nice report about the files previously listed.



I hope that this helps,
Robin

LEARN ABOUT DEBIAN

dpatch

DPATCH(7)							      dpatch								 DPATCH(7)

NAME

       debian/patches/script.dpatch - self applying patch

SYNOPSIS

       debian/patches/script.dpatch -patch [directory]
       debian/patches/script.dpatch -unpatch [directory]
       debian/patches/script.dpatch -pkg-custom [directory]

DESCRIPTION

       A  dpatch is a program that modifies the source tree in a given directory. How it does that is entirely up to the person writing it. It can
       be a script that calls patch(1) with the appropriate options, a complicated perl script that does some deep magic, or  anything	else.  The
       only  requirement  is  that it MUST accept the -patch and -unpatch options, followed by the destination (or working) directory, when speci-
       fied. For the sake of compatibility, the second argument is only present when a working directory was explicitly set with dpatch --workdir.

       For some of the dpatch(1) features to work, the script should follow a common style: there should be a line near the top of the	file  with
       the  following  format: "filename -- author <email>". And one or more "# DP: description" lines. These will be used by dpatch cat for exam-
       ple.

WARNING

       dpatch is deprecated, please switch to the `3.0 (quilt)' Debian source package  format  instead.  See  http://wiki.debian.org/Projects/Deb-
       Src3.0#FAQ for a short guide on how to do it.

EXAMPLES

       One can find dpatch examples under /usr/share/doc/dpatch/examples/.
