Status of a Linux process
All,

I have fair amount of knowledge about shell scripting, but only liitle on system administration.
I would like to know how to analyze whether the particular linux process is alive or not ? If it is alive, will it affect the performace of other process ?.
Also is it still consuming resource? If so, how much resource its consuming?

Example,

aps 31649 13702 0 Feb17 ? 00:00:00 auto_remote

The above process is running since Feb17,2009. I would like to know whether this process is till doing any useful operation. Is it consuming any resouce, etc.,

ctrlaltdel

CTRLALTDEL(8)						     Linux Programmer's Manual						     CTRLALTDEL(8)

NAME

       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS

       ctrlaltdel hard|soft

DESCRIPTION

       Based  on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
       perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft  reset,
       which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1).  If this option is used, the init(8)
       program must support this feature.  Since there are now several init(8) programs in the Linux community, please consult	the  documentation
       for the version that you are currently using.

       ctrlaltdel is usually used in the /etc/rc.local file.

FILES

       /etc/rc.local

SEE ALSO

       simpleinit(8), init(8)

AUTHOR

       Peter Orbaek (poe@daimi.aau.dk)

AVAILABILITY

       The ctrlaltdel command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
