I have a .sh file that I would like to open/execute when I click on it in the Nemo file explorer.  I get an error when I open the folder with the file, select the file,right-click, select Open and Run in Terminal:
I get the following message in a new window:


There was an error creating child process for this terminal
Failed to execute child process: " ... path to .sh file":  Failed to execve: No such file or directory


Note text was execve

If I open a terminal in the folder with the .sh file and enter: bash ...sh   the file executes:


normt@norm-HP-EliteDesk-800-G2-DM-35W:~/Work/AndroidDevelopment/Testing$ bash Install_CdTimer.sh
* daemon not running; starting now at tcp:5037
* daemon started successfully
error: no devices/emulators found
Performing Push Install
adb: error: failed to get feature set: no devices/emulators found
Press Enter
normt@norm-HP-EliteDesk-800-G2-DM-35W:~/Work/AndroidDevelopment/Testing$



I am trying to use the adb command to install an apk file in a android virtual machine running in VirtualBox

What do I need to do to make a script that will execute from a folder?

The .sh file:


#! /bin/sh
# set -xtrace
# @rem  Install some APKs
# /home/normt/Work/AndroidDevelopment/adt-bundle-linux-x86_64-20140702/sdk/platform-tools/adb devices
/home/normt/Work/AndroidDevelopment/adt-bundle-linux-x86_64-20140702/sdk/platform-tools/adb install ./Apks/CountdownTimer.apk
read -p "Press Enter"

Have you set the "x" bit on the shell script's access rights?

It is set.  What else needs to be checked or changed to get the .sh file to execute?

Look at this thread: https://coderanch.com/t/770009/languages/bash-script-execute

Which desktop manager are you using?

I thought that other thread was for script files that were on the desktop.  The ones I am trying to get to work are not on the desktop.

I have the default desktop manager:  GNOME

Does it work with any other scripts?

I am wondering if Nemo hasn't been setup with how to "Open in Terminal"

I have not found any scripts that work.  Although the only ones that I have seen are the ones that I have tried to write.

what is the default Terminal set to?


How do I tell?  I have not changed anything about Ubuntu after the install other than adding a second file explorer: Nemo
I thought Nemo worked better than Nautilus.

Don't know if it matters but what version of Ubuntu?

I get Command not found when I enter cinnamon-settings in the box from Alt-F2
I think the version is 22.04

Do you have any script files that run in bash and that can be executed by clicking on them in a file explorer like nautilus?

Why would I want to change the terminal?

Should I expect bash scripts to work on my system?  Or are they normally turned off somehow and I need to fiddle some settings to get them to work?

I am wanting to see if the default terminal is setup.

You can run the scripts in your terminal, as I see it the problem is "Open and Run in Terminal" execution in Nemo. Which is why I am wanting to check the default terminal setting.

This is a different issue.

The script in the original use -- #! /bin/sh -- which worked in the terminal
This one is -- #! /usr/bin/bash

It looks like bash isn't in the /usr/bin/ file
Since  you didn't get the issues with running the adb in your first script, I would recommend staying with #! /bin/sh

In this post it sounds like one of the settings Nemo looks for missing when not using the Cinnamon desktop environment.

And thanks for trying to help.  My expectations were obviously too high.  On windows I write batch files all the time.
I was hoping it would be as easy on Ubuntu.  Obviously it isn't.

Oh, I forgot to add, you may need to logout and back in or reboot for the gsettings update in Nemo.

Can you logout and then try this again?

It can be, but some programs are grouped together and when you pull one of them out (Nemo in this case) unexpected things may happen.

When I edit the script file, copy a line, paste it into a terminal and press enter, the contents of the line executes as expected.
I believe I documented that in an earlier post/

Thanks Ron. I started a new script file with the first line and then copied into it the command lines from the other script file and it now works.

The Bash language lacks some features commonly found in more modern programming languages, such as strong typing, object-oriented programming (OOP) support, and advanced data structures. However, Bash is primarily designed as a shell scripting language for automating tasks and interacting with the command line, so its simplicity and focus on system administration make it well-suited for certain use cases.
