That may let you exit cleanly, but how will the process ever end from this stopped state?

disowning the process should allow you to exit cleanly. nohup ksh ... & disown
Ok..i have rewritten the command as follows

Code:
nohup ksh cat_Duplicate_Records_Removal.ksh </dev/null >/dev/null 2>&1 &

earlier when i run the command in background and when enter(CR) is pressed the job got stopped . Now with the inclusion of </dev/null that problem is solved.SmilieSmilie


when i type disown in HP-UX ksh ..I get the following

Code:
$ disown
ksh: disown:  not found

is there any alternative to disown?

Not that I'm aware of. I guess I should have started by asking your OS and $KSH_VERSION.

You should be able to exit by trying exit twice. But I've not dealt with such a system, at least not for a long time.

Nowadays I keep a terminal multiplexer (tmux or GNU screen) running that I can detach and reattach to. My current jobs stay running in virtual terminals which I can just switch to and view the output instead of putting them unattended in the background. Of course, this isn't the right solution for everything but it's worth investigating if you're able to install such software.

I think the command 'at' can be also used to run scripts without getting stopped on logout.

at command

The command 'at' can be scheduled to run a script at a particular time or immediately

ksh93 supports the disown command. You must be using a really old version of ksh such as ksh88 or pdksh.

I think if you don't have disown, you don't need it either.
