Comment 2 Samuel Padgett 2017-08-04 10:14:06 EDT
I can reproduce in the web console, but not in the xterm.js demo against current xterm.js master. So this is either a bug specific to the web console / kubernetes-container-terminal or fixed in xterm.js 2.9.0.
Comment 3 Samuel Padgett 2017-08-04 11:01:55 EDT
I'm able to reproduce this with `oc rsh` outside of the web console. This doesn't seem to be specific to the web console terminal.
Comment 4 Samuel Padgett 2017-08-04 11:32:45 EDT
Also reproducible with Docker outside of OpenShift using this command

docker run -it --entrypoint=/bin/sh yapei/hello-openshift
Comment 5 Jhon Honce 2017-09-01 13:55:29 EDT
Using these rpms of docker, I cannot reproduce the issue.


$ env |grep -i term

$ docker run -it --entrypoint=/bin/sh yapei/hello-openshift

sh-4.2# exit

xterm beeped when I attempted to delete into the prompt.
