Unix: list out Pattern occurrence (count)

Need to search a pattern occurrence (count) in a specified file.
Below is the details


$ cat fruits
apple apple
ball ball
apple
ball ball ball
apple apple apple
cat cat
cat cat cat
apple
apple
Note: If I'll use the grep command with -c option then it'll count the 1st occurrence in the lines but not the repeated occurrence like

$ grep -ic apple fruits
5
but here apple is occurring 8 times.

Perhaps you could translate all whitespace characters to newlines before piping into grep.
