It depends how you are planning on using it. Is this within a shell script loop perhaps? ksh and others should allow you to slice the string too. I avoid the word cut as that is a command.

Consider the code:-

#!/bin/ksh

for file in *
do
   file_trimmed="${file%??}"
   echo "File \"$file\" is trimmed to \"$file_trimmed\""
done

If you explain more about what the end goal is, then you may get a better suggestion.

I hope that this helps.
