submit a ksh script in background - Shell Programming and Scripting

captainzeb · #1 11-07-2003

I submitted a ksh script in the background last night before leaving work:

./ping_test &

When I came into work this morning I discovered that it had stopped running when my session timed out.

So, I then tried it again this morning and logged out before letting it time out as one unix site suggested that. Same result. The script stopped running.

I need this script to run until I manually kill it.

Any ideas? I am using an AIX 4.3.3.

Thanks.

Not an AIX guy, but I'd guess you just use nohup to tell the script not to die when you logout.

nohup scriptname.ksh &

would do it in Solaris (what I know best).

Thanks man. That's it!

maybe set the environment variable TMOUT to 0, and use nohup as rhfrommn suggested.

export TMOUT=0

You can also check out a very cool and usefull program called screen.

It lets you start a new shell and then deattach it with ctrl+ad ... then you can logout..

then login again and just use screen -r to resume it..

You will have more control with screen than with nohup. (great for IRC-clients and stuff like that)
