Shell Programming and Scripting

hi all,

i've a shell process, which checks for particular size for a directory, which is running in background, i found that when the terminal is open of that process or called script process, it has terminal id, which will keep on getting size of the directory.

Code:

asak   24329     1 13 01:15 pts/49   00:00:01 sh ck.sh

but when the terminal is closed. the process will be

Code:

asak   15350     1  1 00:16 ?        00:01:01 sh ck.sh

then its not checking the size, nothing it will do.. how to avoid this, can we do something, where , when user closes terminal also, the process in background must excute.

Regards,
asak

Please provide the content of your 'ck.sh' script

How do you start the ck.sh script?
If it is started from terminal, then it is tied to that terminal, and will be sent HUP signal when terminal closes. This can be prevented by starting it with 'nohup', like

Code:

nohup ./ck.sh &

Or, you could start the process in subshell, like

Code:

(./ck.sh &)

, which will also detach the process from terminal.
You will still see the question mark, when you look at the processes with ps(1), but that shouldn't make you worry -- it just means that the process isn't tied to a terminal.

But it seems your script is running when you close the terminal, it just is not doing what you want it to do. So it may be an error inside the script and we would need to see the contents...
