What did you do?

Installed golang on a Raspiberry PI and ran go clean -cache but got an "unknown command" error.

After running go install (I installed Hugo from it's source). go clean -cache is now a recongised command and doesn't error.

What did you expect to see?

I would expect the command to not say it is an unknown command on a fresh install and if there is nothing to clean, either exit with such a message or no message at all. Saying it is an "unknown command" is misleading.

$ go clean -cache
$ echo $?
0

What did you see instead?

$ go ​clean -cache
go ​clean: unknown command
Run 'go help' for usage.

how did you install go?
I don't see how it's possible for clean to be an unknown command.

I was installing on my Raspberry PI 4 running Rocky9 - I have the commands on hand:

curl https://go.dev/dl/go1.20.2.linux-arm64.tar.gz --output /tmp/go.tar.gz --location
tar -zxvf /tmp/go.tar.gz -C /usr/local
echo 'export GOROOT=/usr/local/go' | tee -a /etc/profile.d/golang.sh
echo 'export PATH=$PATH:/usr/local/go/bin' | tee -a /etc/profile.d/golang.sh
source /etc/profile.d/golang.sh

Then immediately ran go clean -cache.
As I said after running go install github.com/gohugoio/hugo@latest it no longer happens 🤔 bizarre!

You've got a zero width space character before clean (it's also in the command you pasted above):

Oh ahaha! Nice spot. No idea how that got there. Okey, no issue here. Closing...

Just wanted to comment I was hit by the exact same error. Surprisingly when copying and pasting from Google! Apparently Google inserts that character there for some reason.
