Editing substr

=== Removing the first and last characters from a string === The following [[script]] demonstrates how the [[substr]] function and [[length]] functions can be combined to remove the first and last [[character]]s from a [[string]]: {{{ awk BEGIN { mystring="knights" print substr(mystring,2) # remove the first letter print substr(mystring,1,length(mystring)-1) # remove the last character print substr(mystring,2,length(mystring)-2) # remove both the first and last character } }}}

Summary:

This change is a minor edit.
