thank you rakeshawasthi it works
but how can I make the script goes through subdirectories ?
I've tried this, but all the files comes into the "i" variable, so the script doesnt work :
IFS=
for i in $(find . -type f | awk -F"/" ' { print $2 } ' )
do
if [[ `basename "$i" .chm` != "$i" ]]; then
exit
fi
echo $i
done
