Comparing multiple of files

[rickatx]

Hello everyone! I am fairly new to Linux and was needing some help on a comparing more than 2 files. I am try to come up with something that would compare at least 10+ different files to a master file and give me an output of what is missing.

Example would be:

a.txt, b.txt, c.txt, d.txt compare each of them to the master.txt file, than output the missing text for each file into new file.

I came across comm and diff commands, am I looking in the right place or is there a much easier way of doing this?
Any help would be greatly appreciated!

I think you would need to compare them one at a time,
like
a.txt and master.txt
and write them into new file
now check
b.txt with master.txt and so on..

To compare files I normally use Kompare

You could write a bash script to do it. The file names would be your arguments. Then you would need a loop something like:

for filename in $* do
diff filename master.txt>>logfile
done
