like its shown in top command on HP-UX page keeps on refreshing till u hit <CNTR-C>
to make it more simple
its should update server CPU usage only without quitting ..
only lines marked with "*" should change as soon as they find new value for that server in logfile.
The system I work on, produces several kinds of status-files in a single directory. I would like to be able to see the files as they are added to this directory.
I was wondering if it would be possible to get a "tail -f" alike view of the ls-command, in such a way that a newly added file is... (4 Replies)

First month learning about the Linux terminal and it has been a challenge yet fun so far. We're learning by using a gameshell. I'm trying to display a certain line ( only allowed 1 command ) from a file only using the head or tail. I'm pretty about this answer:

cpu
CPU(1) General Commands Manual CPU(1)NAME
cpu - connection to cpu server
SYNOPSIS
cpu [ -h server ] [ -c cmd args ... ]
DESCRIPTION
Cpu starts an rc(1) running on the server machine, or the machine named in the $cpu environment variable if there is no -h option. Rc's
standard input, output, and error files will be /dev/cons in the name space where the cpu command was invoked. Normally, cpu is run in an
81/2(1) window on a terminal, so rc output goes to that window, and input comes from the keyboard when that window is current. Rc's cur-
rent directory is the working directory of the cpu command itself.
The name space for the new rc is an analogue of the name space where the cpu command was invoked: it is the same except for architecture-
dependent bindings such as /bin and the use of fast paths to file servers, if available.
If a -c argument is present, the remainder of the command line is executed by rc on the server, and then cpu exits.
The name space is built by running /usr/$user/lib/profile with the root of the invoking name space bound to /mnt/term. The service envi-
ronment variable is set to cpu; the cputype and objtype environment variables reflect the server's architecture.
FILES
The name space of the terminal side of the cpu command is mounted on the CPU side on directory /mnt/term.

Binds and mounts done after the terminal lib/profile is run are not reflected in the new name space.
