Shell Programming and Scripting

Hi all,

I am stuck on a shell script issue and need your inputs:
I have a parent script A.ksh which call in another script B.ksh. At the start of the B.ksh, we export the .profile of another user and then call Informatica jobs.

Issue
When I run my jobs from the command prompt, it works perfectly fine. However, when I run my job from nohup utility in the background i.e.

Nohup /{path}/A.ksh > /tmp/trades.log &

To verify the status of job, when I run the ps -ef |grep A.ksh command, I get the following message:
[1]+ Stopped Nohup /{path}/A.ksh > /tmp/trades.log &

However, when I run the ps -ef |grep A.ksh command, it shows the normal running status.

While debugging, the execution flow goes to the B.ksh but gets stuck at export .profile statement. When I kill the parent script A.ksh, then execution flow moves ahead of the export .profile and starts executing the informatica jobs. We can not modify B.ksh file, as its provided by the clients and used by other scripts.
When the trades.log file is checked, the following error is received at the export .profile command:
Stty: :I/O error
I also tried using the same user to log in whose .profile is exported in the B.ksh script.

Your ideas and suggestions are welcome.

Thanks!

AFAIK there is no ksh command "export .profile". What is actually in the script? We would expect perhaps ". /home/username/.profile"?
The "stty" errors are because "stty" requires a real terminal and there is no real terminal in background. Though it can be avoided with an "if [ ! -t 1 ]" test for every "stty" statement it would be better to make a new profile-type script containing only those statements which are relevant to running your database process and executing that script as ". /path/scriptname" instead.
