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

"Bfree": 3067411,
"Bavail": 3067411,
"Files": 3067428,
"Ffree": 3067381,
"Fsid": {

},
"Namelen": 255,
"Frsize": 4096,
