Hi

I have a file named "a  b" which contains two spaces. Doing a

$ test -f a\ \ b && echo true
true

echoes true as expected. However doing a

$ test -f "a b" && echo true || echo $?
1

exits with code 1. Is this behaviour expected?
Thanks

Daniel Reichelt

Yes.  "a b" != "a  b".  Check your spacing.

Nevermind it boiled down to a stupid bashism. Anyways, thanks!
