OK. Build a sandbox, create dummy xml files with "Status" in their first line, and then run the respective commands. Experiment with parameters. Use commands with whole absolute paths. Come back with results and details. If your problems exists only with your sensitive data, and you cannot disclose those, you're doomed. I am / we are not interested in your data, but to analyse that strange behaviour, we need more than an uttered "It doesn't work." As long as there's no data to work on, I'm giving up.

Might I suggest an alternate?

You are finding files ending .xml and for each of them in the order that they are found, you are running your grep The issue you might have is that the grep command working on a single file on some OS version may produce no output if you use the -l flag.

Try adding /dev/null into the grep command so that you always have two files and grep may behave differently.
find . -type f -name "*.xml" -exec grep -l "Status" {} /dev/null \;

Note how the /dev/null is part of the grep command, i.e. it's before the \; and so it is taken as an input file. It is not redirecting output to as it is normally used for or redirecting standard input to be reading 'nothing' from.

I hope that this helps.

find: cannot execute "-exec": The system cannot find the file specified.

That's what I'm talking about....

The difference is the wild card! Why would that matter?
The difference is not the wild card; the difference is the -exec -exec. Try changing:
find . -name "*.xml" -exec -exec ls -al {} \; -exec grep -l "Status" {} \;

find . -name "*.xml" -exec ls -al {} \; -exec grep -l "Status" {} \;

and see what happens.

I never heard the results of you trying the suggestion I made in message #16 in this thread. What were the results when you tried that suggested command line?

It show's the files correct files along with all of the details... I don't understand why it won't grab them without the
ls -al part

When I remove this section. The commands act like they run then just return with a prompt but no filenames... It takes like 45 minutes for that to happen...

I really do appreciate all of the help that everybody is giving me! Big THANK YOU ALL!

---------- Post updated at 01:32 PM ---------- Previous update was at 01:30 PM ----------

This command line takes 45 minutes and returns nothing!
find . -name "*.xml" -exec grep -l "Status" {} \;

While this one comes right back showing all of xmls plus their details!
find . -name "*.xml" -exec ls -al {} \; -exec grep -l "Status" {} \;

Does anybody have a clue why?

It's not running the second half of those commands. (The grep -l part)....

I put in this code per status and got back all statuses..
find . -name "*.xml" -exec ls -al {} \; -exec grep -l "AStatus" {} \;
