Clarification regarding nohup.out
Hi,

I am creating two shell scripts for Database backup and the output has to be routed to nohup.out file.

We will also be running the scripts in the background as
nohup.out <script_name> &

Do I manually need to create a nohup.out file in the directory from where the scripts are going to be executed?

Regards,
Narayan

Did you already read the manpage for nohup?

Here's the link to Solaris 10 manpage for nohup:http://docs.sun.com/app/docs/doc/816...nohup-1?a=view

You may want to re-read this:
Quote:
If nohup.out is not writable in the current directory, output is redirected to $HOME/nohup.out. If a file is created, the file has read and write permission (600. See chmod(1). If the standard error is a terminal, it is redirected to the standard output, otherwise it is not redirected. The priority of the process run by nohup is not altered.
Also, from the same man page:
Quote:
The C-shell (csh(1)) has a built-in command nohup that provides immunity from SIGHUP, but does not redirect output to nohup.out. Commands executed with `&' are automatically immune to HUP signals while in the background
