K9s: Shell: First entered character lost

Created on 30 Apr 2019 · 4Comments · Source: derailed/k9s

Describe the bug
When entering into a shell the first character typed into the shell is lost, all other characters afterwards work. This is a bug in a library k9s uses

After writing this issue up I realized it's a duplicate of: https://github.com/derailed/k9s/issues/165 (why was this issue closed? seems like it should be kept open for tracking purposes. Also there is a posted "fix" but I couldn't seem to figure out how to apply it)

To Reproduce
Steps to reproduce the behavior:

Deploy a pod kubectl run -it --rm --image alpine bugtest
Go to the pod list
Select the pod named bugtest*
Press s to get a shell
Attempt to run the command cd /bin <enter>
Notice the first keypress is lost

Expected behavior
The shell would contain

# cd /bin
/bin #

@mcristina422 Thank you for the report! The fix is more of a hack ie sending an extra cr to work around the problem. The owner of the lib is aware and yet no fix ;( since the correct fix is actually involved. You can help by voting this issue up. For now, I made a habit of just pressing entrer when I shell in. I know this is annoying.
