I would also like to do so. Is there any way we can collaborate on this as I am also new to Golang.

[rajneeshbajaj]

I can also assist, please let me know.

[hanjunlee]

@neel229 @rajneeshbajaj I'll create a PR where we can work together first and let you know. Sorry for late.

[hanjunlee]

@rajneeshbajaj @neel229 I've created the draft to work (#3962). I'm planning to add options (--selector, --field-selector) to these commands:

• stop
• terminate
• resume
• retry

Please comment if you have any questions.

@simster7 One question, how could I add a unit test for codes of command?

[simster7]

We're refactoring our CLI testing code right now, but for now you can add them under test/e2e/cli_test.go
