#!/bin/sh

for file in *
     do
        echo $file # instead of the full file name, i want the extension
only
     done

how to display $file extension only?
thanks

If your /bin/sh is POSIX compliant (or you can use bash or ksh):

        echo "${file$##*.}"

Otherwise:
        echo "$file" | sed 's/.*\.//'
or:
        echo "$file" | awk -F\. '{print $NF}'
