What happens if you call the shell script directly? An example would be "exec /var/tmp/xxx_bash.sh" ... does that retain the environment variable to allow it to run successfully?

    If i run the script myself yes there is no issue as that is the first thing I checked but I have now some leads, so I will do more testing. Still I used "bash script.sh" or "./script.sh" for personal tests, so maybe the "exec" changes the shell, so a nice suggestion.

      I don't think "exec" necessarily changes the shell, but "exec bash script.sh" vs "exec script.sh" would launch a child BASH process, most likely without the environmental variables you need. Can you try without specifying bash and let me know how it goes?

        Added "HOME=/root  <linux bash command>" in the script.sh file and it now works.
