kbash.sh

#!/bin/sh
# Starts a bash within a container running on Kubernetes while initializing
# the terminal type to xterm and the size to your actual terminal size. Makes
# it possible to have vi, more, etc work in a usable way until PR #25273 is 
# merged. Derived from a snip by Hubert Chen (https://github.com/hubt)
