I wonder if this will work for you. Create this file:

Code:
# cyto.awk

BEGIN { FS=":" }

!MATCH {
        print "You must set the MATCH variable" >"/dev/stderr"
        exit 1
}

(!RGX) && ($0 ~ MATCH) && /COMPND/ {
        getline
        gsub(/[;, ]*/, "");
        RGX="[" $2 "]"
        FS=" ";
        print "RGX is "RGX >"/dev/stderr"
} RGX && ($5 ~ RGX) && /ATOM/

Use it like:

Code:
awk -f cyto.awk MATCH="CYTOCHROME C" inputfile1 inputfile2 ...

tracker-extract(1)						   User Commands						tracker-extract(1)

NAME

       tracker-extract - Extract metadata from a file.

SYNOPSYS

       tracker-extract [OPTION...] FILE...

DESCRIPTION

       tracker-extract reads the file and mimetype provided in stdin and extract the metadata from this file; then it displays the metadata on the
       standard output.

       NOTE: If a FILE is not provided then tracker-extract will run for 30 seconds waiting for DBus calls before quitting.

OPTIONS

       -?, --help
	      Show summary of options.

       -v, --verbosity=N
	      Set verbosity to N. This overrides the config value.  Values include 0=errors, 1=minimal, 2=detailed and 3=debug.

       -f, --file=FILE
	      The FILE to extract metadata from. The FILE argument can be either a local path or a URI. It also does not have to  be  an  absolute
	      path.

       -m, --mime=MIME
	      The MIME type to use for the file. If one is not provided, it will be guessed automatically.

       -d, --disable-shutdown
	      Disable shutting down after 30 seconds of inactivity.

       -i, --force-internal-extractors
	      Use this option to force internal extractors over 3rd parties like libstreamanalyzer.

       -m, --force-module=MODULE
	      Force  a particular module to be used. This is here as a convenience for developers wanting to test their MODULE file. Only the MOD-
	      ULE name has to be specified, not the full path. Typically, a MODULE is installed  to  /usr/lib/tracker-0.7/extract-modules/.   This
	      option can be used with or without the .so part of the name too, for example, you can use --force-module=foo

	      Modules are shared objects which are dynamically loaded at run time. These files must have the .so suffix to be loaded and must con-
	      tain the correct symbols to be authenticated by tracker-extract.	For more information see the libtracker-extract reference documen-
	      tation.

       -V, --version
	      Show binary version.

EXAMPLES

       Using command line to extract metadata from a file:

	       $ tracker-extract -v 3 -f /path/to/some/file.mp3

       Using a specific module to extract metadata from a file:

	       $ tracker-extract -v 3 -f /path/to/some/file.mp3 -m mymodule

ENVIRONMENT

       TRACKER_EXTRACTORS_DIR
	      This  is	the directory which tracker uses to load the shared libraries from (used for extracting metadata for specific file types).
	      These are needed on each invocation of tracker-store. If unset it will default to the correct place. This is used mainly for testing
	      purposes.

FILES

       $HOME/.config/tracker/tracker-extract.cfg
