Hi, Scrutinizer:

Your interpretation is indeed correct, but its correctness hinges on export always returning 0. I mentioned that not to nitpick, but as a heads up for newbies.

Regards,
Alister

Hmmm. POSIX says export returns 0 and doesn't mention any possible error conditions. However, some shells' export builtin can return a non-zero status. Perhaps it's better to be safe than sorry and not treat export's return as a given.

I appreciate the nitpick-appreciation Smilie

But still then I am back to my original point and that it is unlikely what the author intended, especially given the error message, so we better correct the author. BTW, do you ever check return codes of export statements in your scripts?

I agree. Your interpretation is faithful to the intent of the original version. The way the original code is written, it assumes export cannot fail.

Do I ever check export's return status? No comment :P

Hehe Smilie
@ctsgnb: We all seem to agree. Could we have your final seal of approval? Smilie
