test(1): Obsolescent logical operators

test(1): Obsolescent logical operators

[Martin Gebert]

Hi Michael!

As I just learned from this discussion

http://unix.stackexchange.com/questions/267335/how-can-i-check-that-two-input-values-are-correct-in-a-bash-script

the -a and -o operators of test(1) are marked obsolescent:

http://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html#tag_20_128_16

Yet the Linux man pages don't contain a hint to that.

Cheers,

Martin

That page belongs to another project. See
