From reading the comments to the question, it seems as if you have misunderstood the question in the assignment. It asks you to
- Put the command(s) that you used in some other question into a new file called
- Try executing that new file.
- Make the file executable by all.
The file is not hidden away somewhere on the system; you should create it. Once you have, a slightly modified version of the
chmod part of your (too advanced) solution will be enough. No
find will be used in the answer, as far as I can tell.
