The /dev/null makes sense in the case there is only one file in the directory tree. Or one more file than can be put into one argument list.
So yes the /dev/null should be there.
Yes, you are absolutely correct in saying that the /dev/null should be there. Without it, there is a chance that the script will produce output from the last file processed without displaying the pathname of lines extracted from that file.
What I was trying to say in post #5 (and said very poorly) was that the code supplied in post #1 (which did not have /dev/null in the grep command invoked by xargs) also suffers from this problem. This doesn't apply to this use of grep, but there are some cases where you have to use -- or /dev/null to avoid having a filename like -x.txt being treated as a list of options instead of as the name of a file to be processed. Cases where this would apply include:
could fail with certain filenames while:
would work correctly no matter what filenames were present (assuming that the list of pathnames matching *.txt doesn't exceed ARG_MAX limits).
