In Finder, when I create an archive ("Compress items..."), the resulting zip archive has .DS_Store files in folders and files have resource forks. How can I create a zip archive suitable for cross platform sharing from Mac OS X?
zip -r -x .DS_Store directory.zip directory
zipremoves extended attributes and ACLs by default
find directory -name .DS_Store -delete; ditto -ck --norsrc directory directory.zip
-kuses PKZip (zip) instead of CPIO
COPYFILE_DISABLE= tar --exclude .DS_Store -czf directory.tgz directory
tarto remove extended attributes and ACLs instead of creating
The files that start with
._ are AppleDouble files (not resource forks), and they are used to store extended attributes and ACLs.
Extended attributes are used to store the quarantine status of files, the source URLs of files downloaded from the Internet, information about aliases (aliases stop working if extended attributes are removed), Spotlight comments, the encoding of files saved with TextEdit, and so on.
You can list extended attributes and ACLs with
ls -l@e. You can remove extended attributes and ACLs recursively with
xattr -cr .; chmod -NR .
