Hello All,
I have a list of short programs (over 200) to run and it is a hassle to sit and execute each one of them one after the other.
What I'd like to know is if it was possible to create one file which would list all these commands and all I need to do is to execute this one single file.... (2 Replies)
Hi,
I am thinking about writing a log daemon for a multi-processed ksh application (yes - I know that high-level language would be a better option).
My question is as follows:
If many processes (many scripts) will try writing to a single log file:
print "message" > common.log
Will it work or... (2 Replies)

Hello,
I would like to pipe two variables into awk, but I don't know how to do.
Each variable, "a" and "b", are in fact a list of data. They are not files.
So to get awk to work with it I am using:
echo $a | awk 'FNR==NR{print $1}FNR!=NR{print $4}'
The above works, but when I am... (5 Replies)

IVMAN-LAUNCH(8) System Manager's Manual IVMAN-LAUNCH(8)NAME
ivman-launch - launch script for Ivman
SYNOPSIS
ivman-launch [ --exit-with-session <cmd> ] [ OPTIONS ] [ COMMAND [ ARGS... ]]
DESCRIPTION
ivman-launch is a simple script used to launch Ivman. Its sole purpose is to ensure Ivman is closed at the end of a user's login session.
You can use it if your session manager does not properly close Ivman when you log out.
ivman-launch supports the same command-line options as Ivman, and one additional option: --exit-with-session. Thus, there is no point
using ivman-launch if you do not need to use this option.
If you supply a COMMAND (with optional ARGS), the the specified command will be run after ivman is started, and ivman will be killed after
that command exits.
OPTIONS --exit-with-session <cmd>
ivman-launch will block until the command 'cmd' terminates, at which point it will kill Ivman and exit itself. If the command 'cmd'
is not running when ivman-launch is started, Ivman will exit immediately. Note that this option implies Ivman will be called with
the '--nofork' option. option.
--debug --nofork --system
These flags be passed to the launched ivman command.
EXAMPLES
ivman-launch --exit-with-session xinit &
The ivman process will be started, then the xinit process is watched. When the xinit process exits, ivman is killed. Placing this
command in an ~/.xinitrc file would cause Ivman to launch in the background when your session begins, and exit when your session
ends:
ivman-launch /usr/bin/x-window-manager
The ivman process is launched, then /usr/bin/x-window-manager is run, when x-window-manager exits, ivman is killed. This is an
example of how ivman might be launched from Xsession in order to chain several programs together in one session.
