#21923 — How to do chown or chgrp

What is the best way to run the unix chown and chgrp commands in Java?

I only need to run these commands on one file at at time.

Runtime exec or the newer ProcessBuilder.

Surely the 'Java' way (in 1.7 at least) is

java.nio.file.Files.setPosixFilePermissions

As owner and group are not in PosixFilePermission
then surely not.

But it is close.

Files getFileAttributeView with PosixFileAttributeView will
provide setOwner and set Group for a programmatic solution.

Arne

PS: There is also Files setOwner but as it has no setGroup, then I
     would go for the other.

Ah yes, setPosixFilePermissions would be chmod.

My mistake

How about Files.setOwner ?

The OP needed chown and chgrp

chmod - Files.setPosixFilePermissions
chown - PosixFileAttributeView.setOwner
chgrp - PosixFileAttributeView.setGroup

Seems to be one way to do it.

If you need speed, you will want to write some JNI or find a JNI
library that already does what you want.
