I don't get any shellchecks

[Archie-2021]

Hello,

I just installed the extensions via :CocInstall coc-sh and it seems like install was successful. But I don't get any shellchecks , only see some addintional results in my autocomplete from bash-language-server. Also don't know how can I get a shellexplain for part of a code I have written. I assumed that everything else is installed automatically from node. Should I install anything additional like packages for shellcheck and shellexplain for it to work? Or should I have to add stuff to coc-setting.conf file?

Thanks

You need to install shellcheck. It's in the package shellcheck-bin if you use Arch Linux's AUR.

I had both shellcheck and shfmt installed, neither works and vim does not do lint or reformat.
I can run shellcheck or shfmt outside vim just fine and they do the work as expected.
