Dear cartrider,
  • What have you tried so far?
  • What is your OS and version?
  • Have you searched for help before posting?
  • Have you looked at the manual page for cut ?
Most importantly, what have you tried so far?


Presuming that you are at the shell prompt or in a shell script and that you want to get the last bit of $string1, but how should we split it? You would need to tell us:-
  • What format the string will always be in (space delimited, fixed width, number of fields etc.
  • What other output apart from Normal completion we will have to expect
There are lots of ways to do this, but it would be best if you can steer us what you are considering and therefore you will learn better with what you are familiar with.
