macOS – Does not hide “/System/Volumes” Mount Points

[faxotherapy]

Using any of these options does not work on macOS:

duf --hide-mp '/System/Volumes/Data'
duf --hide-mp '/System/*'

It stills shows:

/System/Volumes/Data
/System/Volumes/Preboot
/System/Volumes/Update
/System/Volumes/VM

However, the following works…

duf --hide-mp '/'

It seems there is a problem on MacOS when the MP name contains capitalized letters. I have built from source and I can hide my TimeMachine MPs like so:

❯ duf --hide-mp '/dev, *com*'

Note that I cannot use pattern *TimeMachine* or *timemachine* as both patterns won't hide the MPs. However, *com* and *apple*, respectively, are working.

But if I want to hide the /System MPs, using /System/* or *System* still yields all MP as shown above. Nothing is hidden.

❯ duf --hide-mp '/dev, *com*, *System*'

What works is to use *ystem* like so:

❯ duf --hide-mp '/dev, *com*, *ystem*'

Also see #106. There may be a fix in PR #245.

@fuchsg yep this PR will fix it, go-wildcard is now in 2.0.2 an upgrade can be nice to.
But @muesli is not very active, I don't know the state of the project.

[muesli]

Thanks for confirming, @IGLOU-EU. See comment on #245.

You make me lying muesli 🤣
Ok, I will update my PR, thanks.
