Product: Documentation Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: Manual Pages Assignee: bugs@FreeBSD.org Reporter: sean@rogue-research.com CC: doc@FreeBSD.org The man page for 'cp' does not contain the word "extended" nor "attribute". I was very surprised to see that even 'cp -p' apparently does not preserve = the extended attributes of a file. I'd argue 'cp -p' behaviour is wrong, but at the very least it should be documented. By contrast, the macOS 10.13 man page says: "-p Cause cp to preserve the following attributes of each source file in the copy: modification time, ac= cess time, file flags, file mode, user ID, and group ID, as allowed by permissio= ns.=20 Access Control Lists (ACLs) and Extended Attributes (EAs), including resour= ce forks, will also be preserved." A simple sentence to warn that cp -p will blow away EAs would help. We're talking about data loss here. :( example: root@freenas[/test]# lsextattr user A.txt=20 A.txt DosStream.com.apple.TextEncoding:$DATA DosStream.AFP_Resource:$DAT= A=20=20=20 DosStream.AFP_AfpInfo:$DATA DOSATTRIB=20=20=20=20=20=20 DosStream.com.apple.lastuseddate#PS:$DATA root@freenas[/test]# cp -a A.txt A2.txt=20=20=20=20=20=20 root@freenas[/test]# lsextattr user A2.txt A2.txt --=20 You are receiving this mail because: You are the assignee for the bug.=
