Subject: `[[ -n $VAR ]]` equal to `[[ $VAR ]]`?
Date: Fri, 10 Apr 2015 03:23:29 +0200 [thread overview]
Message-ID: <mg78mg$vqb$1@ger.gmane.org> (raw)
Hi,
this is kind of a follow-up to
http://www.zsh.org/mla/users/2011/msg00284.html .
Basically the solutions were `((+VAR))` for zsh and `[[ -n
${VAR+stuff} ]]` for bash and zsh.
Now my question is, isn't `[[ -n $VAR ]]` equivalent to `[[ $VAR ]]`?
(`[[ -n ${VAR+stuff} ]]` equivalent to `[[ ${VAR+stuff} ]]`)
Thorsten
