shell execution time calculations
I am writting a script in the ksh shell and am trying to find a way to report the total execution time of the script without requiring the user to specify the time function when executing the script.
Does anyone have any examples they have used. I have been setting up two date variables (one at the beginning $START_TIME and one at the end $END_TIME) and then do some calulation of the difference and display is to the user in minutes. No matter what I do it keeps giving me syntax errors.
any help
