This will show the sum of hits on all lines in the input file:
Code:
$ cat infile
dog cat rat apple banana dog lion tiger dog
cat rat apple banana dog lion tiger dog
lion tiger dog
$ awk '{for(c=0;c<=NF;c++){if($c == "dog"){h++}}} END{print h}' RS= infile
6

This would show it per line:
Code:
$ awk '{for(c=0;c<=NF;c++){if(c==0){h=0}; if($c == "dog"){h++}}} {print h}' infile
3

expack

expack(1)						      General Commands Manual							 expack(1)

NAME

       expack - manipulate Flex files

SYNOPSIS

       expack -a FLEXFILE FILE...

       expack -c FLEXFILE FILE...

       expack -x FLEXFILE [INDEX]

       expack -i MANIFEST

       expack -l FLEXFILE

DESCRIPTION

       expack  is  a command-line utility that lets you extract and create Flex files.	Flex files are archives (which means that they act as con-
       tainers for other files, somewhat like directories) used by Ultima 7 to store most of its data. Note that the names of the  original  files
       are not stored in the Flex -- files are only retrievable by their index.

   Modes of operation
       -a Add --NOT IMPLEMENTED YET.  FUTURE ENHANCEMENT-- This command adds one or more FILEs to the end of FLEXFILE.

       -c Create
	      This command takes one or more FILEs and bundles them into FLEXFILE, overwriting it in the process.

       -x Extract
	      Lets  you extract the files contained within FLEXFILE.  If INDEX is given only the file at this position will be unpacked, otherwise
	      all files are extracted. The created files will be named index.u7o.

       -i Input
	      Similar to "Create", this command creates FLEXFILE from a number of input files. However, "Input" takes the names of the input files
	      from MANIFEST instead of the command line.

	      MANIFEST must be a list of file names, one per line. The first name is that of the Flex file that is to be created, the rest are the
	      input files used in building it.

       -l List
	      This command lists the contents of a FLEXFILE.  It gives you the number of files contained within the Flex  file,  as  well  as  the
	      length of each file.

EXAMPLES

       expack -a animals.flx bee.wav
	      Adds bee.wav to the Flex file animals.flx.

       expack -a animals.flx hamster.wav snake.wav donkey.wav
	      Adds hamster.wav, snake.wav, and donkey.wav to the Flex file animals.flx.

       expack -c animals.flx duck.wav cat.wav cow.wav dog.wav
	      Creates a new Flex file animals.flx containing duck.wav, cat.wav, cow.wav, and dog.wav.

       expack -x text.flx 17
	      Extracts the file at position 17fromtext.flxinto17.u7o.

       expack -x text.flx
	      Extracts all files from text.flx into files named 0.u7o, 1.u7o, 2.u7o, etc.

       expack -i wavlist
	      With wavlist reading:

	      jmsfx.flx
	      ant.wav
	      bee.wav
	      cat.wav

	      will create a new Flex file jmsfx.flx consisting of ant.wav, bee.wav, andcat.wav.

       expack -l text.flx
	      Lists the number and lenghts of files contained in text.flx.

BUGS

       The "Add" command (-a) does not work yet.
