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


    ]
}
