The UFS, NFS, and TMPFS file systems have been enhanced to include extended file attributes. Application developers can associate specific attributes to a file. For example, a developer of a file management application for a windowing system might choose to associate a display icon with a file.
Extended attributes are logically represented as files within a hidden directory that is associated with the target file.
Many file system commands in Solaris provide an attribute-aware option that you can use to query, copy, modify, or find file attributes. For more information, see the specific file system command in the man pages.
