How to get diskusage in golang?

[jianfeng ye]

Now I want to get the disk usage in golang.

I know I can got that by call command "df ", but I want to know is there any other method to get the diskusage status?

I found this package using go-search.org:

Hello,

In this thred https://groups.google.com/forum/#!topic/golang-nuts/Ld41Pdk28tY Han-Wen Nienhuys propose :

s := syscall.Statfs_t{}
errNo := syscall.Statfs(ts.orig, &s)

http://golang.org/pkg/syscall/#Statfs
http://golang.org/pkg/syscall/#Statfs_t

Incidentally, that's exactly what the library I suggested does under the covers:

On a POSIX system, you can os.Stat("/") and calculate the disk usage
from the values provided in the system-specific fields of the
FileInfo value. This will be syscall.Stat_t.
See man stat(2) for more info.

On Windows, you should possibly call GetDiskFreeSpace() API function.

Thanks, I got that, But further, it has a param call "path", I want to show all the disks status like "df"

Filesystem     1K-blocks     Used Available Use% Mounted on

/dev/xvda1      20641404 14142760   5450120  73% /

what should i do?

On *nix, you can do http://linux.die.net/man/2/statvfs, on Windows - http://msdn.microsoft.com/en-us/library/windows/desktop/aa364937(v=vs.85).aspx

Pick one (or both) and write code that uses the syscall package to call one (or the other, or both). 

Or, you can cheap out and call "df" from a shell process you start in Go, and parse its output...

have fun!

That means I want to know how to get all potitions in golang?

if this SO question is any indication, it doesn't appear that there is a system call for listing mount points.  Depending on how portable you need this code to be, reading from /proc/mounts may be your best bet.

Does this work in windows? There's no cross platform way to do this using the std lib, I guess?

No, it will not. And no, there is not.

tldr: proposal to add Statfs to windows syscall package as first step towards a cross-platform way of doing this, it was based on GetDiskFreeSpace API (as used by https://github.com/StalkR/goircbot/blob/master/lib/disk/space_windows.go) but it was thought unnecessary for stdlib and preferred to be in an external library.

Makes sense to me, you would have gotten my +1 :)
