This is both wrong (insecure) and clumsy. You can't create a temp file
this way. If the file already existed, then you're using someone else's
booby
thanks for the answer Stephane; dont get me wrong, I do understand that
using another variable removes the need for some special variables (do you
need $REPLY if you can always use "read v" and be happy with it?). Dont you

nothing. sometimes it is just not practical (see my answer to Chet's
comment) and sometimes you just want to get that
Thanks for taking time to answer. Of course it is the issue of

Dear All,
one thing I missed for some time now, is the ability to access the
argument passed to test, or any argument on the right hand side.
I needed it so I made a quick hack, which I attach as a reference.
It allows to access arg in the the -f $arg easily, e.g.:
[ -f /tmp/myfile ] && { echo
