Shell script question on variables
I have the following script that is supposed to calculate the runtime of the script as a whole (edited for brevity):
Code:
#!/bin/sh

# set endtime and print elapsed time
set starttime=`date +%s`
echo "Value of starttime: " $starttime
sleep 1
set endtime=`date +%s`
echo "Value of endtime: " $endtime
set elapsedtime=$endtime - $starttime
printf "Script took %02d:%02d:%02d to complete\n" $((elapsedtime/3600)) $((elapsedtime/60%60)) $((elapsedtime%60))

The output however is as follows:
Code:
# ./runtime.sh
Value of starttime: 
Value of endtime: 
Post installation took 00:00:00 to complete

Does this mean that the regular shell (ie not bash) does not recognise variables? What do I do to make this script work without resorting to bash?

Thanks in advance
