I don't have a preference but unix/MacOS commands vary:
- ls command: The ls utility exits 0 on success, and >0 if an error occurs.
- grep command:

1 No lines were selected.

- unzip command:

1 one or more warning errors were encountered, but
processing completed successfully
anyway. This includes zipfiles where one or more files
was skipped due to unsupported
compression method or encryption with an unknown password.
2 a generic error in the zipfile format was detected.
Processing may have completed
successfully anyway; some broken zipfiles created by other
archivers have simple work-
arounds.
3 a severe error in the zipfile format was detected.
Processing probably failed
immediately.
4 unzip was unable to allocate memory for one or more
buffers during program
initialization.
5 unzip was unable to allocate memory or unable to obtain a
tty to read the decryption
password(s).
6 unzip was unable to allocate memory during decompression
to disk.
7 unzip was unable to allocate memory during in-memory
decompression.
8 [currently not used]
9 the specified zipfiles were not found.
10 invalid options were specified on the command line.
11 no matching files were found.
50 the disk is (or was) full during extraction.
51 the end of the ZIP archive was encountered prematurely.
80 the user aborted unzip prematurely with control-C (or
similar)
81 testing or extraction of one or more files failed due to
unsupported compression methods
or unsupported decryption.
82 no files were found due to bad decryption password(s).
(If even one file is successfully
processed, however, the exit status is 1.)
So perhaps something along the lines of
