But clear-cache (and some other commands) can be used globally or site-wise.
In my bench, the notif Please specify --site sitename always showed up.
And if using --site option then the notif of Error: no such option: --site.
But maybe you’re right that I put the --site option wrong.
Note:
From --help the [OPTIONS] are at the end of the command.
But in --help for bench itself the [OPTIONS] is right after bench.
Yes I know this. But it doesn’t answer my question about the warning.
Even, I tried using bench manager and the Bench Manager Command shows it failed (with the same warning), but executed well.
So I actually don’t really have to be worry about the warning but it just disturbing.
Well, thank you anyway.
I will try the new Bench 5.2 which doesn’t need sudo to setup supervisor and see what happen
