I have always used "sudo" with this because I didn't know why I was getting an operation permitted error when doing so. Until I found out that if the effective user is a member of the target group www-data, the sudo isn't needed.The Wikipedia clearly says that:The chgrp (from change group) command may be used by unprivileged users on Unix-like systems to change the group associated with a file system object (such as a file, directory, or link) to one of which they are a member.
I am wondering why the chgrp manpage or info pages do not mention anything about that. It would be very helpful to add that piece of very crucial information to the manpage/info pages.Best regards,--
Wouter Thielen
