It might be safer to use expr "$0" instead of expr $0 in case $0 contains spaces.

I agree, but that's from the original version checking code by chriscool.
The same goes for an empty string as output, hence the digit captured in both regex alternations at lines 39/52.

@whyrusleeping and @mateon1 I am not sure what you think is dump.
My opinion is that expr exiting with code 1 when it returns 0 is really dump indeed!
It looks like it comes from the fact that it can be used for arithmetics.

@chriscool Look good to you? |
