Depending on what exactly you're trying to do, there could be a couple ways to do it. Say you have a variable...
$VAR
...and you want to pull the 4th through the 6th character out of it. You can echo it to the screen...
echo $VAR | cut -c4-6
...or you can assign it to a variable...
CHARACTER4=`echo $VAR | cut -c4-6`
...if you don't know how many characters long the word is, you can leave the end number off the cut command...
echo $VAR | cut -c4-
...and it will echo the variable, minus the first three characters. Get it? Email me if you need more help, at ::email removed:: .
