[SOLVED] Remove first character of a string in Bash

Issue

I need to calculate md5sum of one string (pathfile) per line in my ls dump, directory_listing_file:

./r/g4/f1.JPG
./r/g4/f2.JPG
./r/g4/f3.JPG
./r/g4/f4.JPG

But that md5sum should be calculated without the initial dot. I've written a simple script:

while read line
do
    echo $line | exec 'md5sum'
done

./g.sh < directory_listnitg.txt

How do I remove the first dot from each line?

Solution

Set the field separator to the path separator and read everything except the stuff before the first slash into $name:

while IFS=/ read junk name
do
    echo $name
done < directory_listing.txt
