Macromates

To eliminate the extended attributes of Textmate execute the following command on Terminal:

defaults write com.macromates.textmate OakDocumentDisableFSMetaData 1  

This will eliminate the @ of the permissions of the files, those which we can see executing ls -al (-rw-r–r–@) Also this will allow to copy this files to systems that doesn’t suppport extended attributes (like Samba), and not see files ._filename created at all.
