stty: : I/O Error
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!

times
times(1) User Commands times(1)
NAME
times - shell built-in function to report time usages of the current shell
SYNOPSIS
sh
times
ksh
times
DESCRIPTION
sh
Print the accumulated user and system times for processes run from the shell.
ksh
Print the accumulated user and system times for the shell and for processes run from the shell.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
