    DESCRIPTION<\/div>\n<\/div>\n<\/li>\n
  22. \n
    \n
    <\/div>\n<\/div>\n
    \n
    The xattr command can be used to<\/span> display<\/span>, modify or<\/span> remove the extended<\/div>\n<\/div>\n<\/li>\n
  23. \n
    \n
    <\/div>\n<\/div>\n
    \n
    attributes of<\/span> one or<\/span> more files, including directories and<\/span> symbolic<\/span> links.<\/div>\n<\/div>\n<\/li>\n
  24. \n
    \n
    <\/div>\n<\/div>\n
    \n
    Extended attributes are<\/span> arbitrary metadata stored with<\/span> a file<\/span>, but separate<\/span><\/div>\n<\/div>\n<\/li>\n
  25. \n
    \n
    <\/div>\n<\/div>\n
    \n
    from<\/span> the filesystem attributes (such as<\/span> modification time<\/span> or<\/span> file<\/span> size<\/span>).<\/div>\n<\/div>\n<\/li>\n
  26. \n
    \n
    <\/div>\n<\/div>\n
    \n
    The metadata is<\/span> often a null-terminated UTF-8<\/span> string<\/span>, but can also<\/span> be<\/div>\n<\/div>\n<\/li>\n
  27. \n
    \n
    <\/div>\n<\/div>\n
    \n
    arbitrary binary<\/span> data<\/span>.<\/div>\n<\/div>\n<\/li>\n

    One or<\/span> more files may be specified on<\/span> the command line<\/span>. For<\/span> the first<\/span> two<\/div>\n<\/div>\n<\/li>\n

    \n

  32. \n
    \n
    <\/div>\n<\/div>\n
    \n
    the display<\/span> of<\/span> the file<\/span> name is<\/span> usually suppressed (unless the -v option<\/div>\n<\/div>\n<\/li>\n

  36. \n
    \n
    <\/div>\n<\/div>\n
    \n
    the names of<\/span> all<\/span> extended attributes are<\/span> listed. Attribute names can also<\/span><\/div>\n<\/div>\n<\/li>\n
