Hi Listmates,

Current code:
CURNUM=`ls /etc/apache2/sites-enabled|cut -d- -f1|tail -1`
NEWNUM=`expr $CURNUM + 1`
NUMLEN=`expr length $NEWNUM`

if [ -z $CURNUM ]
then
  FID="001"
elif [ $NUMLEN -eq "1" ]
then
  FID="00$NEWNUM"
elif [ $NUMLEN -eq "2" ]
then
  FID="0$NEWNUM"
elif [ $NUMLEN -eq "3" ]
then
  FID=$NEWNUM
Fi

Basically searches /etc/apache2/sites-enabled for filenames that are like:
001-site1
002-site2

And finds last value and then adds +1 to it. Let or expr doesn't want to
work with numbers starting with 0, makes sense, but I haven't found a way to
force it either, so I'm wondering if there is a clever solution to this,
bash-wise, or this should do it ? (taking there won't be 4 digits of sites;
more likely it will not hit 2 digits, but better be safe than sorry!)

Thanks.
