STATFS(1) STATFS(1)

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
] }
