I am trying to test if a file exists and then source it. My problem is the test succeeds even if the variable is empty! If I pass no argument at all, it still succeeds. To give you an example: $ unset bla $ [ -f $bla ] && echo yes yes $ [ -f ] && echo yes yes I don't understand this behaviour. I would have expected this to fail since $bla is blank. Can someone please explain? Thanks a lot. PS: I am not subscribed to the list, could you please cc me to any responses. -- Suvayu Open source is the future. It sets us free.
