using bash:

Code:

for file in *
do
    ff=`echo $file | cut -d '.' -f1`
    echo -n "$ff "
    echo ${#ff}
done

Code:

ls | awk '$(NF+1)=length'

If I understand your question, the following should work or you can modify it to do what you need.

for i in `ls -1`
do
val=`echo $i | cut -d '.' -f1 | wc | tr '\t' ' ' | tr -s ' ' | sed 's/^ //' | cut -d' ' -f 3`
val=`/usr/bin/expr $val - 1`
echo $i $val
done

If you want to exclude the file extension from the character count, try this instead:

Code:

ls | awk -F'.' '{ print($0, NF>1?length-length($NF)-1:length) }'

is more elegant. In my case, I just never took the time to learn awk. Thanks for the alternative.
