I have made a application launcher for Thunderbird (called mythunderbird) on a remote machine using the .XWinrc file.
menu apps {
xterm exec "xterm"
"Emacs" exec "emacs"
notepad exec notepad
xload exec "xload -display %display%" # Comment
mythunderbird exec "ssh -X mckserver.mckserver.apollo3.com thunderbird"
}
This starts beautifully with a multiple of keystrokes (right click XWin > (pint to Applicatoins) > click mythunderbird.
Can someone tell me how I can add such a menu to a desktop short cut? Putting a short cut to run "xterm" then logging in to the remote server and starting Thunderbird is easy, but a lot of steps and clicks.
What I really need to do is know what to change in this default short cut for starting xterm:
C:\cygwin\bin\run.exe -p /usr/X11R6/bin xterm -display 127.0.0.1:0.0 -ls
What I like about the functionality of the XWinrc application is that it has a clean execution of Thunderbird without the residue of an extra terminal left running. If I start it outside XWinrc, I have Thunderbird running, but also an extra xterm running.
The way I got it to work was to make a script in cygwin in my home directory (/home/dave/mythunderbird) which does the ssh call.
In the windows shortcut, set the target C:\cygwin\bin\run.exe bash -le /home/dave/mythunderbird
run.exe stops the command window being displayed and bash -le runs the script in bash from a login shell

First of all, this may seem like a duplicate question but I have searched stack overflow/various other forum sites and still haven't managed to find a solution.
A few example forum posts I have reviewed to prove I've done my research before asking a question:

Run ssh and immediately execute command

There's hundreds more but I won't include them all.
I essentially need a shell script to open a command prompt on windows, login to a remote linux system and run a command.
I am aware this can be done with the following:
start cmd /k ssh user#host ls
But the problem with the above is that the ssh connection is closed upon completion of the task.
I am also aware I can keep the ssh connection open by adding:
bash -l
in some cases.
For my use case, I need to run a launch file for ROS (robot operating system) and for this I need to see the output from the command.
And when attempting to run roslaunch launchFile.launch (in place of ls above):
start cmd /k ssh user#host "roslaunch launchFile.launch"
the command prompt returns
bash: roslaunch: command not found
I've obviously sanitised the specific name of my launch file but
roslaunch launchFile.launch
runs perfectly if I login to the linux PC first:
ssh user#host
then run the command.
I have achieved this exact use case on MacOS but I now need reimplement the same solution on windows:
osascript -e 'tell app "Terminal"
do script "ssh quantum#172.23.199.1 \n
roslaunch launchFile.launch"
end tell'
Thanks in advance for any help or advice.
Try this :
start cmd /k ssh user#host "/full/path/to/roslaunch launchFile.launch; exec /bin/bash"

I need to run a Perl script for several days processing something. On a linux Centos server, from the SSH terminal I run this command:
nohup perl script.cgi 2>&1 &
This runs the script in the background and writes the output to nohup.out.
The problem when I close the SSH terminal or even my internet connection disconnects the script terminates.
I need to keep this command running in the background on the server after I close
the SSH terminal.
You can use Terminal multiplexer tools like screen, byobu or tmux.
I personally use screen. so install it on remote server via sudo apt-get install screen.
ssh into server
open screen session by screen -S sessionname
Now run your command (background/foreground both works)
now detach to your session by command ctrl+a then press d.
Now shut your pc and enjoy
now come back ssh into server then use command screen -x sessionname to reconnect the detached session.
Hurray! script is still running.
you can either use screen or run the command using supervisor in linux systems.
you can install screen using sudo apt install screen
then use following command to run it.
screen -S test_command
nohup perl script.cgi 2>&1 &
Then press ctrl+a and ctrl+d to leave that session running for whatever amount of time required until your server reboots.
If you want to stop the command use screen -x test_command, then ctrl+c and use ctrl+a and ctrl+d to close screen or ctrl+a and ctrl+d to leave the screen session as it is.
The only way I was able to run the command and exit the shell and keep the command running is using the "at" tool to schedule the job like this using the full script path:
echo "perl /home/username/www/script.cgi" | at now + 1 minute
I'm pretty new to Linux / Raspberry PI.
I want to run a command from a shell script in a new shell window since commands like "cvlc music.mp3" (VLC PLAYER) would block the shell until playback has beenn finished.
Therefore it would be nice to export the playback command to another shell
Is this correct?
gnome-terminal && lxterminal don't seem to be an option for the distribution
for testing purpose I created two dumnmy shell-scripts:
[start.sh]
#!/bin/sh
lxterminal\
--title="MyScriptWindow" \
-e "bash -c ./exe.sh;bash"\
[exe.sh]
#!/bin/sh
echo "Hello World"
[output]
root#raspberrypi:/home/pi# ./start.sh
(lxterminal:1315): Gtk-WARNING **: cannot open display:
If I've understood correctly, you are doing all this only because you want the shell to be released at the execution of your cvlc.
You only need to detach it from shell standard output and run it as a background process
nohup cvlc music.mp3 &
is this enought ?
You could also run the program in background
$> ./test.sh &
Or use screen
Using these command you wont block your shell.
I'm running a game server on a remote server where I use a detached screen instance to leave it running.
I'm now creating a script that can be used to shut down the server, back up all the vital files and start it up again, however I'm having a few difficulties with dealing with the screen.
I assumed that I could just switch into the detached screen in the script (after the server had already been shut down) by calling screen -r in the script.
But that doesn't seem to work because if I run the script from outside screen it just launches the server in that session.
screen -r
cd ~/servers/StarMade/
sh StarMade-dedicated-server-linux.sh
screen -d
This is what I thought would do the trick but it doesn't. Maybe somebody can help me out here. I'm not a bash expert. In fact this is propably my first bash script that doesn't include "Hello World". Thanks.
Your script, as in your example, will get executed by your sell, not the one in the screen. You need to tell the running screen to read a file and execute it - that's what the -X option is for.
Try
tempfile=$(mktemp)
cat > $tempfile <<EOF
cd ~/servers/StarMade/
sh StarMade-dedicated-server-linux.sh
EOF
screen -X readbuf $tempfile
screen -X paste .
rm -f $tempfile
You can leave screen running in a 2nd terminal session to see what happens.
So normally people ask how to forward x11 to the local machine, but rather I want to leave the application running on the remote box's desktop.
So let say I ssh from a windows machine (using putty) and run xclock & disown. If I then walked over to my desktop and look at the screen and see xclock running on the linux machine.
Any way to do that? Using Mint 13.
This works for me once I'm ssh'd in:
export DISPLAY=:0; nohup <command> &>/dev/null &
For example:
export DISPLAY=:0; nohup iceweasel &>/dev/null &
When you're ssh'd in normally, set the DISPLAY variable with export DISPLAY=0:0 (0:0 being the display of the target box), and then you can run your command as you normally would. If you want to be able to close the ssh session, prepend the command with nohup: nohup ./yourcommand > dev/null.
h4bo --> That worked. just had to make the script.
First part of learning ssh stuff. Now instead of leaving teamviewer (a remote desktop program) open all the time, I can launch when I need it and then use it.
i guess
nohup ssh -X <ip address> <application name>
I recently had to do some python tkinter development on a Raspberry Pi with Thonny, where I wanted the tkinter graphics to show on the Pi's X server. For this specific purpose, I created a /usr/bin/pythonx script which simply consisted of:
#!/bin/bash
DISPLAY=:0 python "$#"
This wrapping technique works when Thonny ssh's into the Pi where the user is also logged in at the GUI desktop, as the ssh user has access to the .Xauthority data needed to send X client requests (application) to the server (GUI).
