    Any unix gurus around? Need some help.

    So I have a list of file names in txt format that should be in directory A. Turns out that some files are missing and I need to find out which ones. Is there way to run thru the list of required files from files.txt and spool list of missing files to missing.txt ?

    so I have ---> xargs -a files.txt ......

    Help brother out.

          Ps you may need to sort your list first:
          sort want.txt > sorted.txt

          diff sorted.txt have.txt


          diff is also great for figuring out what changed between two versions of a file:
          diff -Bb file.bak file.html

              Thank you man. I didn't even think that way.
              Thinking more of a programer with loops and ifs.
              Happy holidays to you !!!
