newowner fileschown [
Change the ownership of one or more files to newowner. newowner is either a user ID number or a login name located in /etc/passwd. chown also accepts users in the form newowner:newgroup or newowner.newgroup. The last two forms change the group ownership as well. If no owner is specified, the owner is unchanged. With a period or colon but no group, the group is changed to that of the new owner. Only the current owner of a file or a privileged user may change the owner.
Print information about files that are changed.
Follow symbolic links.
Do not print error messages about files that cannot be changed.
Only change owner and/or group if the current owner and group match those specified in --from. If currown or currgroup is omitted, a match is not required for that attribute.
Change the ownership of each symbolic link (on systems that allow it), rather than the referenced file.
Print information about all files that chown attempts to change, whether or not they are actually changed.
Traverse subdirectories recursively, applying changes.
