STATFS(1) STATFS(1)

statfs - dump the statfs(2) information for PATH to console in JSON format.

statfs PATH

The statfs(2) system call returns information about a mounted filesystem in a statfs_t structure. This tool dumps this information in JSON format. It is developed as part of gocryptfs and written in Go.

The statfs_t structure is architecture-dependent. On amd64 it looks like this:

type Statfs_t struct {


    Type   int64


    Bsize  int64


    Blocks uint64


    Bfree  uint64


    Bavail uint64


    Files  uint64


    Ffree  uint64


    Fsid   struct {


        Val [2]int32


    }


    Namelen int64


    Frsize  int64


    Flags   int64


    Spare   [4]int64
}

See the statfs(2) man page for the meaning of these fields, and note that the field names here are acc. to the Go golang.org/x/sys/unix naming convention, and slightly different than in C.

Get the statfs(2) information for /tmp:

$ statfs /tmp

    "Blocks": 3067428,

    "Bavail": 3067411,


    "Files": 3067428,


    "Ffree": 3067381,


    "Fsid": {


        "Val": [

        ]


    },


    "Namelen": 255,
