Hi all, I have a problem changing permissions to some files using chmod and now I have a doubt about the owner and group of a file, I´ll try to explain. I have 2 users, user1 and user2, both belongs to group1. I have a file with this permissions: -rwxrwxrwx 1 user1 group1 file.txt with user2 I can read, write this file. but If I try to change the permissions with this: chmod 770 file.txt I get the error: operation not permitted, so my doubt is, only the owner can change the permissions to a file?
