MacOS – How to control the Terminal in the current space with AppleScript

You can create a new service using automator (from the applications folder). At the top of the automator window, enter: Service receives 'no input' in 'any application'. Then, in the workflow, add 'Run applescript'. Make the applescript contain the following:

on run {input, parameters}

    tell application "Terminal"
        do script ""
        activate
    end tell

    return input
end run

(You can add any command you like into the do script line between the " " (e.g. something useful to run when terminal first opens like uptime if you like, or just leave it blank).

Save the service as 'Open Terminal' or whatever name you like. It should now appear in your services menu.

Then if you want to add a keyboard shortcut, you just need to go to System Preferences -> Keyboard -> Keyboard Shortcuts tab, select services in the left hand menu, and find your new service (its probably near the bottom). Just click in the space to the right of your service name, and assign it whatever keyboard shortcut you like, and hey presto! it should all work

This is a little bit hacky, but you can achieve this in AppleScript. If there is a predetermined number of tabs you want, and preset commands you wish to run, this isn't difficult.

tell application "Terminal"
    -- Activate it.
    activate

    set targetWindow to 0

    -- Get a window that's not busy.
    -- If there are no open windows, open one.
    if count of windows is greater than 0 then
        repeat with currentWindow in windows
            if currentWindow is not busy then
                set targetWindow to currentWindow
            end if
        end repeat
    else
        do script ""
        set targetWindow to window 1
    end if

    -- Do command 1.
    set firstCommand to "cd ~/Desktop; clear"
    do script firstCommand in targetWindow

    -- Open a new tab.
    tell application "System Events" to tell process "Terminal" to keystroke "t" using command down

    if count of windows is greater than 0 then
        repeat with currentWindow in windows
            if currentWindow is not busy then
                set targetWindow to currentWindow
            end if
        end repeat
    else
        do script ""
        set targetWindow to window 1
    end if

    -- Do command 2.
    set secondCommand to "cd /Applications; clear"
    do script secondCommand in targetWindow

    -- And so on...
end tell

Of course, replace firstCommand with whichever command you actually want to run, and so on. For whatever reason, Terminal doesn't really have an accessible way to create new tabs through AppleScript, so the long, hacky looking line in the middle just tells Terminal to type ⌘T to open that new tab, and then new commands will execute in it.

You can run this AppleScript as is, or use it in Automator to create a new service, which you can then execute from anywhere using a keyboard shortcut if you'd like.
