Hi,

I am not very sure about your requirements, seems you did not specific it.

Suppose you have a file:
a1b3.txt
what should be the result? a01b03.txt or a1b03.txt?

Anyway, follow may help you some or so.

code:
Code:
echo 'Input directory'
read dir
for i in `ls -l $dir | nawk '$9 ~ /[0-9]/ {print $9}'`
do
new=`echo $i | sed 's/[0-9]/0&/g'`
mv $i $new
done

result:
Code:
a.txt --> a01.txt
a1bc --> a01bc
