Re: Numbering

Hi,
I have something 4 u.
for e.g. lets say you want to create a file log.n. so u need to check if it already exists. what you can do is

for i in `ls log*|cut -d"." -f2|sort -n`
do
if [ $n -lt $i ]
then
echo "file exists"
else
echo "creating new log file"
# add you file creation code here
# may b it will something like this
prog 1>log.$n 2>&1
fi
done



hope this helps
