    Hi all

    Is it possible to capture the PID of a command at the time of execution and
    write it to a log file???

    I need to capture the PID at the time of execution, as several instances of
    the command will be run at the same time, i need to make sure that the correct
    process is killed when required.

    an example would be having several instances httpd running.

    running the httpd startup script produces the following output:
    ./scripts/httpd.sh 2>&1 |tee /var/log/jini.httpd.log &
    [1] 1199
    bash-2.03# Mar 29, 2005 8:28:05 PM com.sun.jini.tool.ClassServer run
    INFO: ClassServer started [lib/dl/, port 8082]

    the 1199 is the group process, so i could just use "kill -- -1199". any child
    process die.
    The above pipe to tee does not report the group PID. i just get the
    following:

    bash-2.03# cat /var/log/jini.httpd.log
    Mar 29, 2005 8:28:05 PM com.sun.jini.tool.ClassServer run
    INFO: ClassServer started [lib/dl/, port 8082]

    how can i trap the PID?

    Thanks
    Dan.
