Try this

awk '{for(i=1;i<=NF;i++)a[$i]++}END{print a[cnt]}' cnt=unix input_file

--ahamed

tr " " "/n" <1.txt | grep "unix" | wc -l

Puts all words onto own lines, changing space to carriage-return
greps for the string
give a line count for matches

If you have GNU grep:

grep -o "unix" file | wc -l

@joeyg, I noticed a typo, also wc -l can be replaced with grep -c switch:

tr " " "\n" < file | grep -c "unix"

In case it is undesirable, note that all of the solutions offered will match subword strings.
