newb shell question

I know this is a total begginer question but what is wrong with this picture. My loop wont loop, it just drops me back to the prompt and gives the error "unary operator expected". Any help would be appreciated.

here it is,

#!/bin/sh
selection=
while [ $selection -ne9 ]
do
cat << MENU
1)List files in current directory
2)Display pwd
3)Remove a directory
4)Create a directory
5)Copy a file
6)Remove a file
7)Change directory
8)Mail file to user
9)EXIT
MENU
echo "Enter selection:\c"
read selection
echo "the user selected option $selection"
if [ $selection -eq 1 ]
then
ls
elif [ $selection -eq 2 ]
then
pwd
elif [ $selection -eq 3 ]
then
echo "Name of dir to delete"
read option3
rm -r $option3
elif [ $selection -eq 4 ]
then
echo "Name of dir to create"
read option4
mkdir $option4
elif [ $selection -eq 5 ]
then
echo "Name of file to copy"
read option5
echo "Where to move it to?"
read option55
cp -r $option5 $option55
elif [ $selection -eq 6 ]
then
echo "Name of file to delete"
read option6
rm -r $option6
elif [ $selection -eq 7 ]
then
echo "Name of directory to change to"
read option7
cd $option7
pwd
elif [ $selection -eq 8 ]
then
echo "Name of file to send"
read option8
echo "Who to send it to"
read option88
mailx $option8 < $option88
elif [ $selection -eq 9 ]
then
exit
else
echo "Please enter a valid selection"
fi
done

xcb_set_selection_owner

xcb_set_selection_owner(3)					   XCB Requests 					xcb_set_selection_owner(3)

NAME

       xcb_set_selection_owner - Sets the owner of a selection

SYNOPSIS

       #include <xcb/xproto.h>

   Request function
       xcb_void_cookie_t xcb_set_selection_owner(xcb_connection_t *conn, xcb_window_t owner, xcb_atom_t selection, xcb_timestamp_t time);

REQUEST ARGUMENTS

       conn	 The XCB connection to X11.

       owner	 The new owner of the selection.

		 The special value XCB_NONE means that the selection will have no owner.

       selection The selection.

       time	 Timestamp to avoid race conditions when running X over the network.

		 The selection will not be changed if time is earlier than the current last-change time of the selection or is later than the cur-
		 rent X server time.  Otherwise, the last-change time is set to the specified time.

		 The special value XCB_CURRENT_TIME will be replaced with the current server time.

DESCRIPTION

       Makes window the owner of the selection selection and updates the last-change time of the specified selection.

       TODO: briefly explain what a selection is.

RETURN VALUE

       Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

       If you want to handle errors directly with xcb_request_check instead, use xcb_set_selection_owner_checked. See xcb-requests(3) for details.

ERRORS

       xcb_atom_error_t
		 selection does not refer to a valid atom.
