Find specific word in text file and count it

Question

someone can help me with code? How to search in text file any word and count how many it were repeated?

For example test.txt:

hi
hola
hey
hi
bye
hoola
hi

And if I want to know how many times are repeated in test.txt word "Hi" program must say "3 times repeated"

I hope you understood what I want, thank you for answers.
