nohup makes make_sys_image fail on rp3440/HP-UX11i v2

[newa]

Hi,

I just noticed an intresting thing about make_sys_image - everytime I used it with nohup it would get stopped somehow like the following (running it in the foreground without nohup worked very well.)

Do you know why?

Thanks a lot in advance!

It is possible between the two steps the shell is trying to do tty stuff.
You should redirect stdin also:
nohup /tmp/make_sys_image ... < /dev/null

newa,

You can perhaps do it in two step as below:

1. Put the command in a file.
2. make it executable.
3. Run the file with nohup.



# vi sys_img.sh
/tmp/make_sys_image -d /san02 -s 172.20.123.224 > make_sys_image.log 2>&1


# chmod +x sys_img.sh
# nohup sys_img.sh &


Cheers,
Raj.

Dennis' solution worked. Thanks a lot, Dennis
