Issue
What I want is pretty simple. Given a string 'this is my test string,' I want to return the substring from the 2nd position to the 2nd to last position. Something like:
substring 'this is my test string' 1,-1. I know I can get stuff from the beginning of the string using cut, but I'm not sure how I can calculate easily from the end of the string. Help?
Solution
Turns out I can do this with awk pretty easily as follows:
echo 'this is my test string' | awk '{ print substr( $0, 2, length($0)-2 ) }'
