I am wanting to write a program that runs a program or command-line. Is there are way of making a program that activates a command-line (for example executing 'ps -a -f' or '/home/shared/fah').
In addition to that, I want the program to do a 'ps -a -f' and put the results in a buff, how could I do this.
I thought about this a while ago when reading through a Python tutorial and I googled some and couldn't find an answer. Now I want to know it for Ruby, also, and it's more important now because I want to invoke Ruby with -w.

I tried to install Vlc using the terminal (terminal as root). I've used the command aptitude install vlc. Instead of installing only vlc, my gnome desktop environment was removed, gdm was removed, many more programs was removed!

I have reinstalled Suse 10.1 as dual-boot with Windows XP. I am now unable to get a program to run from the Linux command line. I am familiar with the program and have had it running previously when the machine was Linux-only. Everything else, e.g.Firefox and Office, work fine in Suse.

The problem occurs with all commands - not just this one. isis3Startup.sh is in green on the screen so I assume I should be able to run it - I have never had any problem when it was installed previously.
ipcalc isn't the one I am thinking of. I remember another one that was a bit better, with more options -- easier to use.I remember that if you gave it a CIDR network /23 and an IP, it would list all of the address ranges, network, broadcast for that network..

View 2 Replies View RelatedExample: In rc2.d I have S99test. In it: Code: #!/bin/sh mplayer -playlist "/music/Thom Yorke - The Eraser" Reboot; hear the loveliness; press pause (lirc setup)...still loveliness.
Login as root; "pkill mplay";hear nothing; "/etc/rc2.d/S99test"; more loveliness; press pause...silence! I know that i the former case, mplayer is assigned (for lack of a proper term) to a session, e.g. tty1. Not so in the latter. But why should a program like mplayer not receive (or ignore?) input from lircd, simply because it doesn't have a session? And how can I get mplayer (or any program run from boot scripts) to work with other programs (like lircd)?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
For whatever reason, the "Ctrl-Alt-Fn" sequence has no effect on one of my Ubuntu machines; the sequence is interpreted as ordinary input. I need to get the system to a console because I'm trying to do a dist-upgrade and that's going to bounce gdm etc.
Is there some command-line tool that can be used to switch consoles? I have some vague distant memory of that being possible.
(I'm running Ubunty Jaunty at the moment. Yes I know it's old; I'm trying to march forward.)
I use a few command line programs quite often such as nano and mpc. I'd like to create a shortcut icon to open them rather than opening a terminal and then typing in the program name to open it. For example, how could i open konsole with nano opened in one step?
