Variables are not returning values when called from crontab

Question

When I call my script from crontab the variables are not returning any values. Whereas when I execute it manually (command line) it works fine. I also observed only the $start_time and $end_time are not returning values whereas the $auto_job_name returns "mytext". Could you please help on this?

Contents of my script.

#!/bin/bash

auto_job_name="mytext"

start_time=`grep $auto_job_name job_status.txt`
end_time=`grep $auto_job_name job_status.txt`

echo $auto_job_name
echo $start_time
echo $end_time

Try setting the absolute path of your file job_status.txt – Zumo de Vidrio Mar 23 '17 at 11:25 — Zumo de Vidrio, Mar 23 '17 at 11:25

You might write the absolute path to your job_status.txt file, for example:

#!/bin/bash

auto_job_name="mytext"

start_time=`grep $auto_job_name /path/to/job_status.txt`
end_time=`grep $auto_job_name /path/to/job_status.txt`

echo $auto_job_name
echo $start_time
echo $end_time
