Since my python knowledge is limimted, I've challenged myself to learn as much as possible to help me with my carrere. I'm currently trying to convert a shell script to python, just to give myself a task. There is one section of the script that I'm having issues converting and that is this line:
which basically checks the checksum of "image.iso" against a textfile called SHA256, which contains the correct checksum.
A sample of "SHA256" is below (ignore the same checksum everywhere, it's just for example purposes):
So far, I'm down to this python script:
but I'm stuck as to how I should go about picking up the correct line from the "SHA256" file and then compare the hash (I guess I can do it with "if variable in" or something.
The following find command works on the Korn Shell command line:
find . \( ! -name . -prune \) -type f -name "*.txt" -mtime +100
In the particular directory I'm in, the above find will list correctly the three text files that exist that haven't been modified in over 100 days:

fragiso
FRAGISO(8) System Manager's Manual FRAGISO(8)NAME
fragiso - split rpm packages from an iso and reassemble the iso later on
SYNOPSIS
fragiso make iso fiso
fragiso list fiso
fragiso fill [-m] fiso iso
DESCRIPTION
fragiso can be used to convert an iso file into a fragment file, which is a list describing all of the rpms on the iso and a data chunk
containing everything but the rpms. It is used by drpmsync when an iso needs to be transferred. The idea is that often the rpms on the iso
are already available on the destination host, so it saves bandwidth to first transfer the fragmented iso, copy the locally available rpms,
transfer the unavailable rpms and reassemble the iso file.
fragiso make converts the iso into the fragment iso, fragiso list can be used to extract the rpm information. This information consists of
the offset and length of all rpms and the lead/signature header md5sum plus the header/payload md5sum. To reassemble the iso one has to
copy the rpms at the right offset into a new file and then use fragiso fill later on to provide all data not contained in the rpms. The -m
option tells fragiso to print the resulting md5sum of the iso to stdout. It can be used for verification purposes.
