Thank you for your contribution. I've just checked and your commit doesn't appear to be signed-off. That's something we need before your Pull Request can be merged. Please see our contributing guide.
Tip: if you only have one commit so far then run: git commit --amend --signoff and then git push --force.

Hi @tuananh thanks for your interest. You'll need to go back and fill out the whole PR template which specifically asks you "how did you test this?" :-)

https://github.com/alexellis/arkade/blob/master/.github/PULL_REQUEST_TEMPLATE.md

I understand if some people feel that asking for testing is too much to ask, in which case feel free to close your PR.

For the commit message, we also use a brief sentence starting a verb in the imperative singular for instance: Add kubectx as a tool, you can edit this with git commit -s --amend

Hi, you're going to have to read the readme of the project to find out, and decide if you want to contribute this properly or to close your PR.

@alexellis i made the changes. appreciate if you can take another look.

I also would like to tackle on #123 if this one can be merged.

[alexellis]

This looks a lot better and thanks for testing. Can you show that kubectx actually worked once downloaded and chmod'd?

I would like to see the commits squashed into one, you can find how how to do that on google "squash commits" (git rebase -I HEAD~N where N is the amount of commits you made)

Also - we'll need a fix for the comment about Windows users, or they will end up with a bash file for kubectx with a .exe suffix, which won't work.

Update as per comment.

This looks excellent. You really turned this around into a top quality contribution.
