Hi,
my company is maintaining an patched version of tar because some scripts
expect an exitcode 0 even if the archived files change while creating
the tar file.
I read the tar manual [1] and figured out, that an exitcode 1 should be
uncritical while creating an archive since tar 1.19. I also read the
(patched) sourcecode and didn't find any part which says something else.
However I couln't figure out how to proof that.
So the question is: can I be absolutly sure that an exitcode 1 is only
thrown when a file changes while creating the archive? A possible
command would be "tar --numeric-owner --listed-incremental -cpPf"
Thanks & Regards,
Benibr
