Install xcode command line tools without prompt

install_command_line_tools_no_prompt

do shell script "xcode-select --install"
do shell script "sleep 1"

tell application "System Events"
	tell process "Install Command Line Developer Tools"
		keystroke return
		click button "Agree" of window "License Agreement"
	end tell
end tell

If this is saved as an app named CLT.app, this command will enable the applescript to run without needing to specifically enable it as an Assistive Device in Mavericks.

sudo sqlite3 /Library/Application\ Support/com.apple.TCC/TCC.db "INSERT INTO access VALUES('kTCCServiceAccessibility','com.apple.ScriptEditor.id.CLT',0,1,1,NULL);"

Thanks @pearofducks ! I was wondering why it worked from the AppleScript editor but not from the terminal.

Great script. But now I face a problem: the script exit and raise "The command exited with a non-zero status." when the xcode command line tools is installing

xcode-select --install
sleep 1
osascript <<EOD
  tell application "System Events"
    tell process "Install Command Line Developer Tools"
      keystroke return
      click button "Agree" of window "License Agreement"
    end tell
  end tell
EOD

Very useful. Thanks !
I'm trying to add something to close the last window, when everything is installed... I'm totally new to applescript, but here's what I wrote :

tell application "System Events"
  tell process "Install Command Line Developer Tools"
    keystroke return
    click button "Agree" of window "License Agreement"
    repeat
      if (get properties of button 1 of window 1) contain "Done" then exit repeat
    end repeat
    close every window
  end tell
end tell

Can you tell me where I'm wrong ?

@furiml Did you ever figure out your addition of closing the last window?

You can side step the problem by testing the exit code of xcode-select --install before even launching AppleScript.

Maybe something along the lines of:

xcode-select --install > /dev/null 2>&1
if [ 0 == $? ]; do
    sleep 1
    osascript <<EOD
tell application "System Events"
    tell process "Install Command Line Developer Tools"
        keystroke return
        click button "Agree" of window "License Agreement"
    end tell
end tell
EOD
else
    echo "Command Line Developer Tools are already installed!"
fi

Encountered exception when attempting to run it from Terminal

zsh: parse error near `do'

I don't know what this does anymore as it is from seven years ago, but it is an apple script so you will need to run it with applescript and not zsh

xcode-select --install > /dev/null 2>&1
if [ 0 == $? ]; then
    sleep 1
    osascript <<EOD
tell application "System Events"
    tell process "Install Command Line Developer Tools"
        keystroke return
        click button "Agree" of window "License Agreement"
    end tell
end tell
EOD
else
    echo "Command Line Developer Tools are already installed!"
fi
