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

Would it be possible for a script to duplicate a file and incrementally number it?
File in: XXX_007_0580_xxxx_v0016.aep
File out: XXX_007_0580_xxxx_v0017.aep
If someone knows of a way I'd love to see it.
