Question Background & is considered as Idle

Our Aix Unix has one issue.

If I type xedit &
after 30 minutes, xedit auto shut down.

If I type xedit
xedit will run forward.

I feel this & doesn't perform as it should be.

When I use &, system consider this process as idle.

How to fix this issue?
Does this mean unix env variables not set up right?

Thank you.

David.

When I type xedit, a window pop up for me to type in any text. After 30 minutes, this window close by itself.

Thank you.

Well, your terminal certainly is idle -- sitting waiting at a prompt while you do nothing with it.

Surely there's a way to prevent your background tasks being killed by the idle timer though. They're not killed because they're idle, but because they have open handles to the terminal... something xedit doesn't even need. Try nohup xedit & which should close all references it has to the terminal and prevent it being killed when it closes. Depending on your shell you might do "& disown" instead of just &.

I am using AIX Korn Shell.
Your suggestion is
nohup xedit &

or

xedit & disown

Is this right?

Thank you.

Hi.

disown is a ksh93 built-in. At least up to AIX 5.3 TL12 there is no ksh93 that has disown (citation needed, as Wikipedia would say! At least not on any of my TL12 servers).

Did you try the nohup option?

Neither. nohup xedit & disown
