Plutil

plutil is a program that can convert .plist files between a binary version and an XML version. Currently, there are two versions of this utility.

Apple's plutil
See also: plutil's man page plutil: [command_option] [other_options] file... The file '-' means stdin Command options are (-lint is the default): -help		show this message and exit -lint		check the property list files for syntax errors -convert fmt	rewrite property list files in format fmt is one of: xml1 binary1 json -p            print property list in a human-readable fashion without attempting to convert the actual data (not for machine parsing! this 'format' is not stable) There are some additional optional arguments: -s		be silent on success -o path	specify alternate file path name for result; the -o option is used with -convert, and is only useful with one file argument (last file overwrites); the path '-' means stdout -e extension	specify alternate extension for converted files -r		if writing JSON, output in human-readable form --		specifies that all further arguments are file names
