tmaxx · 04-29-2008, 10:14 AM

hi can anyone help on a script which computes time duration:

given:

a. database archive update time = 15:25
b. current system = 17:15

b-a=duration

thanks in advance

This should really be in the prog forum.

You could write a script in bash, eg cvt hrs to mins, calc total time, then subtract results in mins.
To get hrs

echo "17:15"|cut -d':' -f1
17
mins=$((17 * 60))
1020

etc

Get started and come back to us if you get stuck.
