Of course all Apple tools don't preserve creation dates, which is still topic of the discussion here... - cp -Rp doesn't preserve symlink owners [2] (rdar://4523881) - ditto doesn't preserve symlink owners (rdar://4523882), BSD flags, locked flag, HFS+ extended attributes, ACLs (forgot to file a rdar on these ones...) ditto should (expectedly) mimic the Finder's copy functionality. As such an argument could be made that since the geometry of the files are different the ACL from one file shouldn't apply to the other. - rsync -aE doesn't preserve BSD flags, locked flag, modification date of files with resource forks, ACLs (I'm sure there's gazillions of rdars) It also doesn't appear to be able to copy files with both ACLs and resource forks. It appears to only work if you have one or the other. At least that was the last time I checked. - asr (file-level) doesn't preserve symlink owners (rdar://4523924); in 10.4.6 there's a regression by which it doesn't preserve BSD flags, locked flag, HFS+ extended attributes, ACLs, either (rdar://4523878). I haven't done any investigation of archive formats such as tar, so I can't tell how Apple's tools fare in that respect. # list tarball # note Apple Double created only for file with ACL! ooblek:~/xyzzy2 dshoop$ cd ../ ooblek:~ dshoop$ /usr/bin/tar -tvf xyzzy.tar drwxr-xr-x dshoop/dshoop 0 2006-06-27 14:59:01 ./ -rw-r--r-- dshoop/dshoop 0 2006-06-27 14:57:15 ./file -r-------- dshoop/wheel 223 2006-06-27 14:57:18 ./._fileacl -rw-r--r-- dshoop/dshoop 0 2006-06-27 14:57:18 ./fileacl -rw-r--r-- dshoop/dshoop 0 2006-06-27 14:57:44 ./filebsdflags lrwxr-xr-x root/dshoop 0 2006-06-27 14:59:01 ./filesymlink -> file -rw-r--r-- dshoop/dshoop 0 2006-06-27 14:58:24 ./filexattr # extract tarball ooblek:~ dshoop$ mkdir xyzzy2 ooblek:~ dshoop$ /usr/bin/tar -xv --preserve --atime-preserve -f xyzzy.tar -C xyzzy2/ ./ ./file ./._fileacl ./fileacl ./filebsdflags ./filesymlink ./filexattr This email sent to site_archiver@lists.apple.com
