Capturing a PID.

[Don Harrop]

Thanks Tom,  My original finding of jobs -l doesn't work because there is not associated tty.  The command "jobs" just prints null.  I think your $! will work though.. Thanks!

When you execute your program with the "&" (background process) the shell spits out the process id but I can't seem to redirect that out put to a file.  I don't want to use "pidof" after the fact either in case there is another process running with the same name.

Try this:

<your command> &
echo $! > program.pid

$! is the most recent program executed.
$$ is the current shell script

I've attached a copy of dbXML's startup script and its SYSV wrapper for
a better example.
