NAME

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

SYNOPSIS

statfs PATH

DESCRIPTION

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.

EXAMPLES

Get the statfs(2) information for /tmp:

$ statfs /tmp
{
    "Type": 16914836,
    "Bsize": 4096,
    "Blocks": 3067428,
    "Bfree": 3067411,
    "Bavail": 3067411,
    "Files": 3067428,
    "Ffree": 3067381,
    "Fsid": {
        "Val": [
            0,
            0
        ]
    },
    "Namelen": 255,
    "Frsize": 4096,
    "Flags": 38,
    "Spare": [
        0,
        0,
        0,
        0
    ]
}
