Cli: Show help for command

Created on 9 Jul 2016 · 7Comments · Source: urfave/cli

I have been trying to figure out how to show the help for a command.
I have tried both app -h and app cmd -h without success.

app cmd subcmd -h works for subcomands, so I would assume app cmd -h would work?

@fgblomqvist What branch/release are you using? 😸

I'm on the latest release on the v1 branch (v1.18).

@fgblomqvist So far I'm unable to reproduce the problem you're describing, which means I must not understand 😺❤️ https://gist.github.com/meatballhat/5ad61bdb9b72e8729dd6c88dd3a1d278

I _do_ see some inconsistencies in there that bother me, but that's another issue ...

@meatballhat Hmm interesting. Clearly it's working in your example.
I ran some more tests and concluded the following:
app cmd help works
app help cmd works
app cmd -h doesn't work (it runs the Action function)
app cmd --help doesn't work (it runs the Action function)
I will try to replicate this with an example program...

Very odd behavior.

Thanks for the report @fgblomqvist ! Oddly enough, I tried to do a git bisect and couldn't find a working version with your test code so it is possible that this never worked. Either way, #481 should address it -- let me know what you think
