infinite while do loop problem

hi all,

this is how my scrip looks like

Code:

#!/bin/sh

bindir='/opt/apps/script/bin'
datadir='/opt/apps/script/data'
dir='/opt/apps/script'

while : ; do
     ls -1rt /opt/apps/script/data/check.txt*|tail -1 > /dev/null 2>&1
     if [ $? -eq 0 ] ;then
          chmod +rwx $bindir/dummy2.sh
          lastfile=`ls -1rt /opt/apps/script/data/check.txt*|tail -1` > /dev/null 2>&1
          cp $lastfile $dir/backup/
          cp $lastfile $datadir/IPLIST.txt
     else
         chmod -rwx $bindir/script_check2.sh
         exit 0
     fi
done

Its giving me infinite loop. The check.txt is not in the /opt/apps/script/data/ directory, so I thought I wanted it to do chmod -rwx $bindir/script_check2.sh and exit script straight away.

please help.
