Running a shell script

tomekslesicki

I'm trying to remove a file from the System Library on a Mac. Obviously, I need admin permissions to do this.

Here's a bash script I want to execute:

#!/bin/zsh
# Prompt for password
PASSWORD=$(osascript -e 'Tell application "System Events" to display dialog "Please enter your password:" default answer "" with hidden answer' -e 'text returned of result' 2>/dev/null)

echo "$PASSWORD" | sudo -s rm -r -f "/Library/Audio/Plug-Ins/ComponentsPlugin.component"
echo "$PASSWORD" | sudo -s rm -r -f "/Library/Audio/Plug-Ins/VST3/Plugin.vst3"

killall Terminal

The script is working outside of HISE, so that part is tested.

I can call it with startAsProcess and it's starting, but the problem is that it opens in XCode instead of Terminal on my Mac - it may not be a problem for all users, but I guess it can be for some. Is there a way to make sure it's opened in Terminal, or to run it from within HISE using Background Thread or something? And if so - how? The docs are rather confusing in this regard.

I know that @oskarsh and @aaronventure have mastered this, so if you guys have a spare moment to help me out, it would be really great!

Thank you!

@tomekslesicki Can you show the command in HISE you are using to run it?

tomekslesicki

@d-healey Sure!

The problem is, it will open the .sh file in the default app, which can be changed. I need to run it from Terminal, or from within HISE.

d.healey

@tomekslesicki I see.

I've posted an example of this before, but what you need to do is get a File reference to /usr/bin/bash (or whatever the path is to the terminal on MacOS).

Then you call startAsProcess on that and pass in your remove_file.sh in the parentheses.

Dan Korneff

What about using an AppleScript instead? This will pop up the MacOS system dialog to enter a password.

tomekslesicki

@Dan-Korneff tell me how! :D

Dan Korneff

@tomekslesicki I think something like this:

#!/bin/zsh
osascript <<EOF
do shell script "rm -rf '/Library/Audio/Plug-Ins/Components/Plugin.component'; rm -rf '/Library/Audio/Plug-Ins/VST3/Plugin.vst3'" with administrator privileges
EOF

killall Terminal

with administrator privileges will pop up the password dialog

tomekslesicki

@Dan-Korneff thanks! What extension should I save this under?

Dan Korneff

@tomekslesicki Use the .sh extension and then chmod +x on the file so it's executable.

tomekslesicki

@Dan-Korneff it still opens in XCode here becuase it's set as the default app for .sh files.

@d-healey I found your older post about this where you suggested using:

const oc = FileSystem.fromAbsolutePath("/usr/bin/open");

and then:

oc.startAsProcess(bashScript);

But the problem is I can't figure out the path to shell using this method.

You can type which bash into the terminal and it will give you the path.

tomekslesicki

@d-healey thanks! It should then be

const oc = FileSystem.fromAbsolutePath("/bin/bash");

but it doesn't open the script then.

Ahh.. I see. Well, you have 2 options with that. #1 is to change the extension.
I think the .command will automatically open terminal.

The other option is to use tell application "Terminal" which would activate the Terminal and run your script:
https://superuser.com/questions/195633/applescript-to-open-a-new-terminal-window-in-current-space

I haven't done that before, but here's what GPT says:

Force Terminal to launch and execute the script by explicitly passing the shell command to Terminal.app:

#!/bin/zsh
osascript <<EOF
tell application "Terminal"
    activate
    do script "zsh '${PWD}/DeletePlugin.sh'"
end tell
EOF

This launches Terminal, activates it, and runs your script using zsh, ignoring file type associations

But this is within the script, so won't trigger until the script is running, which will already be in xcode.

What are you passing to startAsProcess?

tomekslesicki

@Dan-Korneff Thank you, changing the extension to .command works like a charm!

Seriously ? I searched for hours and GPT couldn't say more than "use Automator to start the shell automatically..."
Your're the man
