Shell Programming and Scripting

Eg: Script B should run after one hour on the completion of Script A.

>  DATE=`date +%H:%M`
> JOB=`jobhist act abcjob  |tail -1 | awk '{print $6}'`

> echo $JOB $DATE
03:23 09:54

>  DIFF=`expr $DATE - $JOB`
expr: non-numeric argument

JOB=03:23 
DATE=09:54
JOB_SECS=$(echo $JOB | awk -F":" '{print $1*60+$2}')
DATE_SECS=$(echo $DATE | awk -F":" '{print $1*60+$2}')

DIFF=$((DATE_SECS-JOB_SECS))
if [ $DIFF -ge 60 ]
then
  echo start job B
fi

if [ $DIFF -ge 60 ]
