SYNOPSIS
btrfs version
DESCRIPTION
btrfs version prints the version of the userspace btrfs-progs package providing the `btrfs` command. The kernel module version is independent and can be inspected via `/sys/module/btrfs/version` or `modinfo btrfs`.The output is useful when reporting bugs, comparing features against the documented changelog, or scripting feature detection. Recent releases (6.x) also expose built-in features through `mkfs.btrfs --version`, `btrfs-convert --version`, and similar per-tool flags.
CAVEATS
Reports the userspace tools version only, not the running kernel's btrfs implementation. Mismatched userspace and kernel versions are supported but some on-disk features may be unavailable.
