[Koha-devel] Coding guidelines for command-line scripts

Greetings,

This is generally the case and a good rule of thumb, which I support, but
there may be cases of exceptions.

GREP
0: Found
1: Not Found
2: Error
If for some reason the script is grep-like in nature (I'm being 
hypothetical), then it should return like grep.

Generally, scripts won't be, so:
+1 for 0=success and not-0=failure.
