I really have no idea if this is a Cygwin problem, just trying to eliminate
variables.
I believe my Cygwin version is "2.9.0(0.318/5/3)" (from the uname string).
From a mintty window, I use a variation of "kubectl exec" in a script to
run a shell in a container in a pod. It appears to run, and I can run
processes from that shell in the container, but the curious thing is that I
never get a shell prompt from the container. I thought I had gotten this
to work before, in the same k8s cluster, but I'm not certain.
This may be an instance of the pty incompatibility issue of native
Windows programs (which I assume kubectl to be).
Try `winpty kubectl`, after installing winpty, that is.
Maybe someone should put up a winpty cygwin package; maybe I should do it...
The other curious thing I see is that if I execute "echo $PS1" in the shell
in the container, it gives me a reasonable response ("\w \$"), but if I
instead do "env | grep PS1", it returns nothing.
You may have set PS1 in your .profile (or .bashrc) but not exported it
into the environment (export PS1).
