% STATFS(1)
% github.com/rfjakob
% Sep 2019
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
]
}
```
