What the XZ_DEFAULTS in Fedora?

Ask Fedora

In Ubuntu, I’ve to set XZ_DEFAULTS to enable multiple-thread compression in console (GUI still using single thread compression even if XZ_DEFAULTS has set to -T 0).

At least in Fedora 41, the MT feature has been enabled by default.

But I still want to know, what’ the xz options are used by default? Such as -C and -NUM and so on.

Thanks!

As far as I can tell :fedora: uses the defaults set by upstream for this package.
You should be able to get them from the xz man page.

Thanks
