Launcher crash trying to execute a command

Hi everyone,
I'm running XFCE 4.12 on Debian 10.
I want to create a launcher that execute the following command in the terminal:

xfce4-terminal --command "watch -n 1.0 sudo nvidia-smi" && sudo /home/patrick/Scripts/nmonLauncher.sh

Where /home/patrick/Scripts/nmonLauncher.sh contains:

su
export NMON=Mmcdt-
nmon

Running this in the terminal gives the correct output (two windows with nmon and smi), but when i set a launcher to do this, it opens a terminal and suddenly close it.
I have the permission to run the script and nvidia-smi with sudo without password
Maybe I'm missing something.

Try this as the launcher command:

bash -c "xfce4-terminal --command "watch -n 1.0 sudo nvidia-smi" && sudo /home/patrick/Scripts/nmonLauncher.sh"

Re: Launcher crash trying to execute a command

I'll bet it's the quoting in the line causing an issue, but that's a little over my head.

Re: Launcher crash trying to execute a command

Assuming the command shown above works as written(no way to test here) then it's best to format it into a script. If the script works then use the launcher to call the script. As I understand it the interpreter is limited so trying to do too much could overwhelm it. Calling the script instead takes the load off.

Re: Launcher crash trying to execute a command

You can pass xfce4-terminal the "-H" parameter to hold the screen so you can see the message.

But more importantly, how are dealing with the sudo command and the su in the script? How do you enter the password?

It's correct since it works in the terminal but not in the launcher. I tried to make a script but i get no such file or directory on /usr/bin/xfce4-terminal

That parameter had no effects. I don't need to insert the passwords since I have the permission to do so on nvidia-smi and the script

Re: Launcher crash trying to execute a command

That's odd. Try these examples as launcher commands:

bash -c "xfce4-terminal --command 'ls -l'"

...a window should pop up quickly and then disappear.

bash -c "xfce4-terminal -H --command 'ls -l'"

...a window shout pop up and stay open until you manually close it. If there was an error message, you would see it.

Then try this as your command:

bash -c "xfce4-terminal -H --command 'watch -n 1.0 sudo nvidia-smi' && sudo /home/patrick/Scripts/nmonLauncher.sh"

Yeah, I think i wrote it wrong.

try this as your command:

bash -c "xfce4-terminal -H --command 'watch -n 1.0 sudo nvidia-smi' && sudo /home/patrick/Scripts/nmonLauncher.sh"

This worked, thanks you a lot. The problem was double quotes.
