How can I change the owner of a file?

Hi!
To my knowledge only the owner of a file is able to change the preferences (of his/her files).
But how can i change the owner, so that other persons can chage the preferences?

Thanks a lot!

I believe that the users that has write permissions to the file can change its permissions. So you can grant group of users write permissions.

I'm the owner of the file and because of this other persons are not able the change the permissions!

OK, I was wrong. Only owner and root can change the permissions on most of *nix systems.

Hi, On my system I'm the root. But I can't change owner and group. When I open that window, the entries of owner and group are grey. :(

You can change owner/group with SCP protocol and SFTP protocol version 4 and greater. In other words, you cannot change them with SFTP 3 and below (most of the SFTP servers). Read Supported transfer protocols.

Hello,
there must be a local reason but I don't know why.
On my current notebook I have no access to groups/owners (XP SP1)
On my old machine (XP without SP1) I have access.
This has nothing to do with WinSCP version or Linux.

Any idea what I have to change in my current XP?

Thx

See above. You may use SFTP on current notebook, while SCP on old machine.

Had the same problem, here's my solution:

- Open in PuTTY (CTRL-P from winscp)
- change to desired directory (cd .. / cd foldername / dir)

- chown -R new_owner:new_group *
this changes the owner and group of all files and subfolders of the current directory (enter chown --help for more info)

hope it helps! :D

You can setup a custom command for changing the ownership, if you need to do it often:
