I have a desktop shortcut that starts a cygwin bash script and I want the mintty terminal to stay open after my script terminates so that I can look at it's output. For this purpose I'm using the -h always mintty option[1].

The window does stay open but the output is unhelpfully cleared by mintty just as my script terminates(!!!). Seems like a bad joke. Am I missing something? I've verified this behavior even with a one line script with just an echo.

---

Note [1] -h is described like this in the man page:

-h, --hold never|start|error|always



Determine whether to keep the terminal window open when the command has finished and no more processes are connected to the terminal.

I ran a few tests, and the -h always mintty option worked as expected; the screen did not get cleared and the window stayed open.

Here is the exact shortcut "Target" I used for running a script:

C:cygwin64binmintty.exe -h always /usr/bin/bash -l ~/helloworld.bash

I am using mintty 2.7.7 (x86_64-pc-cygwin).

Hopefully, upgrading mintty and/or using the syntax as shown above will fix things for you. If not, you could force a pause within the script itself by adding a read command like so:

echo 'Script end.  Press ENTER to close'

  I was using exactly the same options with mintty 2.7.9 (x86_64-pc-cygwin) so it must be a bug. Thanks for your time Michael.

I was running my script with bash --login so on termination it implicitly calls /etc/bash.bash_logout which includes a line that runs /usr/bin/clear ("to increase privacy").

---

Credits: I found the answer in this bug report which includes this helpful explanation:

>  Hmm, the screen clearing is done by the latest /etc/bash.bash_logout:



# when leaving the console clear the screen to increase privacy   if

[ "$SHLVL" = 1 ]; then

    [ -x /usr/bin/clear ] && /usr/bin/clear   

fi
