Very Computer

Hello

      I've encountered some difficulty while writing my own bash
program, the situation is: I want to know wheather a directory is Empty
or not, if it is, it will echo a message i.e.  " Directory Empty ", and
if it's not, it will ls th files. I wonde how it could be achieved?

 Below I tried putting the ls result into a TEMPVAR, and check if its
NULL, however it didn't work. I wonder where i did wrong or is that way
possible? Any help would be greatly appreciated. Thank you !

# $RECY=a directory

 TEMPVAR=`ls $RECY`
 if TEMPVAR=NULL
 then
   echo "There are currently no files in the directory"
else
  ls $RECY
fi

Thank you very much,
   Leo

I get your idea. How about the following?

--8<--
if [ "$(ls $DIRECTORY)" == "" ]
then
  echo "empty"
else
  echo "not empty"
fi
--8<--

That should work ok.

]# $RECY=a directory

] TEMPVAR=`ls $RECY`
] if TEMPVAR=NULL

This sets TEMPVAR to the value NULL
Try
if [ "$TEMPVAR" == "" ]
] then
]   echo "There are currently no files in the directory"
]else
]  ls $RECY
]fi

   ^^^^^^^^^^^^^^^
there should be
if [ -z $TEMPVAR ]
or
if test -z $TEMPVAR
(the same)
see "man test"
