a simple (Bourne) shell script on system V is:

awk '{ for(i=1; i<=NF; ++i) print $i }' file | sort | uniq -c

prints a sorted list of the words in *file* preceded by a count of the number
of times each word appeared in the file.  I expect this will work on other
systems but don't have enough experience to really know.  To just count the
number of distinct words in file change uniq -c to uniq | wc -l
To list words that only occur once, add 

	| awk '$1==1 { print $2 }'

to the end of the pipe.  There are many other variations on this that will
occur to you as you play with it.
