Take a look at 'man bash', specifically the section on 'parameter
expansion'. You'll see a few entries associated with length that
might be useful. For example:
======== strlength.sh ========
#!/bin/bash
echo "The string has "${#1}" characters"
echo "First 10 characters: "${1:0:10}
echo "Last 3 characters: "${1:${#1}-3:3}
===============================
$ ./strlength.sh 123456789012345.txt
The string has 19 characters
First 10 characters: 1234567890
Last 3 characters: txt
