How to change the command prompt color of a MobaXTerm SSH terminal

Hm, changing background colors could get messy, but changing the color of the prompt when you login to your remove server should be easy. Just add it to your .bashrc file.

Depending on what exactly you want to accomplish, here's a few ideas in AppleScript using your Terminal styles. These are more robust than tput, because this gets reset by colored prompts. etc (at least for me).

This sets all tabs running Python (no SSH server available for testing right now) to Homebrew, the others to Ocean:

tell application "Terminal"
    repeat with w from 1 to count windows
        repeat with t from 1 to count tabs of window w
            if processes of tab t of window w contains "Python" then
                set current settings of tab t of window w to (first settings set whose name is "Homebrew")
            else
                set current settings of tab t of window w to (first settings set whose name is "Ocean")
            end if
        end repeat
    end repeat
end tell

save as script and run as osascript Name.scpt anytime you want to re-color your shells (of course you can wrap this as a shell script or something).

If you want to display all long-running processes differently, use the following condition:

if busy of tab t of window w is true then

Or, you can set the style of a single tab, manually selected:

on run argv
    tell application "Terminal" to set current settings of tab (item 1 of argv as number) of front window to first settings set whose name is (item 2 of argv)
end run

Run it like this:

osascript StyleTerm.scpt 3 Homebrew

-> Third tab of frontmost Terminal window gets Homebrew style!

If you want to modify background windows, replace "front window" with a parenthesized expression like just after "tab". If you always want to modify the selected "current tab", use selected tab instead of tab (item 1 of argv as number).

Add the following to your .bash_profile if the first solution is too manual labour for you:

PROMPT_COMMAND='osascript "/path/to/Name.scpt"'

Now it gets executed before every prompt (only problem: not after starting something, i.e. ssh. But this topic isn't about fancy bash tricks anyway. This is just a pointer.)
