I want to have a script (tcsh/bash/python) that launches a bunch of gnome-terminals (or 1 with multiple tabs). And I want it to execute a command, but keep the shell interactive. Currently, if you type gnome-terminal then it launches a new interactive shell, but if you give it the execute flag, then it executes the command and quits (or stays open, but non-interactive depending on the users gnome-terminal settings).
I have this command which I want to run automatically before I start working. What the command does is dynamic and different for each shell. It takes arguments. So it's not something I can take care of in a .cshrc type file.
As soon as I launch terminal I get the following:
[...]: command not found
[...]: command not found
And it then goes to a $~ prompt as usual. How do I make it so the two commands it is trying to launch don't run upon launching terminal?
Ctrl-c with middle mouse button (MMB) trigger in running bash script trigger.
The key combination Ctrl-C or "^C" with the keyboard triggered on a running bash script stands for "signal interrupt" (SIGINT) and terminates the process.
For my workflow in the test phase, how I could do that with the MMB-Buffer, followed by the modified script command:
Code: Select allscript runs
script runs
script runs
Signal interrupt and rerun with MMB trigger:
Code: Select all^C; ./script.sh
modified script runs
modified script runs

I am working on a small project for making a small configuration tool for ubuntu 9.10 for new linux users, that make their system working easily without knowledge of the linux commands.I created a gui in glade and loaded the gui with my python program to show up, now i wish to have some python codes that can launch a gnome terminal (and also pass some linux commands to it) on the click of a button contained in the glade file.

I will give an example of what I'm trying to do here:

USAGE="

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.

Is there a way to run graphical apps as su without launching from the terminal? For example is there a way to open File Browser as su? And if the only way is via the terminal, then how can I find out the names of apps like the File Browser so I can launch them?
View 8 Replies View RelatedI'm a little confuse regarding how one launches tmux. When I launch my terminal (current gnome-terminal), I would like to have tmux up and running. I'm currently doing this by calling "tmux" in my .zshenv (kind of like .bashrc in bash). This does in fact launch tmux, but has some annoying side effects. First, hitting Ctrl-D to exit the shell, only kills tmux, and leaves the tmux-less gnome-terminal still running. An additional Ctrl-D will kill that as well. Second, when ssh into a box with this setup, I get a second, nested instance of tmux. I don't want tmux to launch again when I ssh. Is this the right approach, how should tmux be launched usually?

How do I stop a user, from gaining access to the internet(port) via a restricted browser? In other words, I want a general user to only to have access to Firefox and no other browsers.
My first approach so far, has been to write a bash shell script. It terminates a program based on keywords from known browsers (opera, asus, ect).
I just added 8 additional vncserver sessions(Xvnc) (using a well-documented procedure my predecessor used) to my RH Enterprise 2.4.21-4 (OK it went by fast) server. This brings the number of session listed in my /etc/sysconfig/vncservers file to ~32. Applications and terminals now seem to choose if they will open or not in the Xvnc session and not all sessions start at boot. I can start them manually, and they will work, but then they stop working properly. You can open a session, view the active desktop, click on menus and associated drop-down items to try and open apps, but the apps/terminals just won't open. Is there a limit to the number Xvnc Sessions that can be managed? If so, what is it? This happens whether I try to connect from a Winddows box or another Linux box.
View 3 Replies View RelatedHaving logged in (to Fedora 11) with a terminal session, what command do I give to spawn the Gnome GUI desktop environment? Background: I'm running two Fedora boxes: one local, and one at the other end of my building (on fast LAN). I have full control/ownership of both boxes.
On the local box, I log-in to my vanilla F11 build, and I get the Gnome GUI automatically. Then I can open a terminal window, 'ssh -X -l myself remotebox; cinelerra' to run Cinelerra nicely in local desktop windows.
But sometimes I want to see my typical user desktop for the remote box. Now, IF the remote box is ALREADY running Gnome, I can VNC to it, etc. But, once having logged-out of the remote box, VNC closes and won't show me a GUI login page. (BTW: The remote box usually has no monitor, as well as being out of reach. So schlepping over to logon to it is a real pain.) So, here's the thing: I can login (to terminal session) and can bring up programs in local windows. But WHAT program do I launch in order to bring up Gnome??
Anyone know how to launch a program from CLI (command line) to a specific viewport? I start programs all the time from the CLI and there are times when I'm in "typing demon" mode and don't want to touch the mouse. Being able to launch a program to a certain viewport (Compiz, w. effects) would be really helpful at times.
I'm familiar with wmctrl and i can use the -a and -c options to switch to and close windows fine. I only have 1 desktop (9 viewports, though), and wmctrl's support for viewport seems limited at best. Ideally, I'd like to launch a program to a specific viewport, but just being able to move an existing one to a specific viewport would work, too.
Please note: I'm talking about moving apps to viewports AD HOC or DYNAMICALLY, not in a fixed way like I believe devilspie and such (and Compiz' Place plugin). Depending on my task, I need to quickly launch several apps to different viewports, and this VARIES for me a lot. ubuntu 10.04 lts / gnome / compiz w. full effects
Running debian wheezy. I noticed recently, whenever I fork a process using "&" from a terminal, such as
Code: Select allleafpad &
it starts up, shows the processid in the terminal, but every time when I close the terminal, leafpad gets killed. However, I create a simple bash script,
Code: Select all#!/bin/bash
leafpad&
exit
The script launches leafpad, then exits out leaving leafpad running, as it should. Is what I mentioned above normal? I'm confused, because I think I used to be able to do this in terminal without it depending on the terminal to stay running.
I guess I'm remembering wrong. As it turns out, commands begun on terminal get closed with terminal unless, as mentioned, you use nohup or start subshell. Process hierarchy and tracking etc.
Here's my linuxquestion I have a bash terminal window opened by next command:
Quote:
gnome-terminal -x bash -c "bash"
Now i need to run different commands or scripts AS ROOT in this terminal window from another terminal. I tried things like
Quote:
sudo echo 123 >/dev/pts/4
The result is 123 in that terminal window, but sudo password is asked in my tab where i entered the command.
I'm trying to do something here:: I'm writing a bash script, I want to [open a new terminal and run a bash command in it] inside the script. I tried to use this, but apparently I get syntax errors.
Quote:
#! /bin/bash
echo "echo Something" > ~/Second.sh
chmod +x ~/Second.sh
xterm -e sh -c ./Second.sh
can't find where is gksudo, it is a part of some pakage but witch one?

i'm trying to spawn a daemon-like java process from php on a unix environment, keep the pid for reference and keep it completely independent from httpd processes. I'm using the following code
$command = 'java -cp /myApp/ MyApp';
exec('nohup '.$command.' >> /myApp/myLog.txt 2>&1 & disown & echo $!', $pid);
$pid = (int)$pid[0];
But it gets killed when you httpd restart. I just want it never to get killed except if i call "kill $pid" command.

I am debugging a project and I noticed the .so files from my installed version of this project are being used when I run the main executable. However what I want is that the modified and compiled libraries (.so files) are being used. This is for testing the software. So I don't want to install these. I tried adding the directory with the .so files in /etc/ld.so.conf and doing ldconfig. However that did not seem to work. How can I let the main executable use the modified .so? I also want to debug this using gdb, so if someone knows what I should do to get those modified .so files being used for execution.
