How do I change the group ownership of a file in Ubuntu?
提问by PuchuKing33
I have a little question on how to change the group owner of a file. At the moment the group of the file is the same as my user name but I want to change it so another user can access that same file and read/write to it.
我有一个关于如何更改文件的组所有者的小问题。目前，文件组与我的用户名相同，但我想更改它，以便其他用户可以访问同一个文件并对其进行读/写。

The syntax would be
语法是
chown user:group file ...
This usually (=when you're not root) only works as long as you are a member of the same group (since otherwise by chown'ing files you could exceed the other user's disk quota).
这通常（=当您不是时root）仅在您是同一组的成员时才有效（因为否则通过 chown'ing 文件您可能会超过其他用户的磁盘配额）。
If you both are in the same group you could also allow write access with
如果你们都在同一个组中，你也可以允许写访问
chmod g+w file
As above this will allow all members of groupwrite access.
如上所述，这将允许所有成员进行group写访问。
If you do not share a common group, all you can safely do is to allow read access to the file so the other user can make a copy of it and edit his/her copy.
如果您不共享一个公共组，您可以安全地做的就是允许对该文件进行读取访问，以便其他用户可以制作该文件的副本并编辑他/她的副本。

Also don't forget to change the file permissions to 660 that will give read, write, permission for the owner ( you ) and read, write permission for the new group.
另外不要忘记将文件权限更改为 660，这将为所有者（您）提供读、写权限，并为新组提供读、写权限。
Example:
例子：
-rw-r----- 1 martin martin 0 Feb 18 21:41 test
$ chown martin:newgroup test
$ chmod 660 test
-rw-rw---- 1 martin newgroup 0 Feb 18 21:41 test
