Subject: [ilugd]: How to redirect the pid of a process when running it in >background
Date: Mon, 27 Jan 2003 03:40:01 -0800 (PST)
HI List,
I am running a command in background on Unix(Solaris)
by suffixing it with & and in order for this command
to run uniterrupted, I am prefixing it with nohup. I
want the pid returned by it to be trapped in some
file. The command is something like this:--
$ nohup rmiregistry& > abc.out
The problem is that it returns the pid on the console
but does not redirect it to the file. I have tried
this command in many different styles eg:--
$ nohup rmiregistry& 2>abc.out
$ nohup rmiregistry& 1>abc.out
$ nohup rmiregistry& 0>abc.out
and some other stupid combinations but nothing seems
to be working
Suggest me a solution
No PID is coming in the nohup as well. Infact even if
i try the command without nohup option this way:--
$ rmiregistry& > abc.out
still there is no output in the file. This is probably
because the PID returned is not the output of the
command, thats why. Please suggest a solution
Thanks in advance
Try running the following commands $ nohup rmiregistry& > abc.out
as u were running it Immediately after this $ echo $! > PidFile PidFile should contain the PID of the required process
<quote>From man bash
! Expands to the process ID of the most recently executed background (asynchronous) command.

You may like to read up further the "jobs section" of man bash you will find it contains much more information pertaining to your needs.
