Question how to count number of times each word exist in a file
I'm trying to count the number of times each word in the file exist
for example if the file has:
today I have a lot to write, but I will not go for it. The main thing is that today I am looking for a way to get each word in this file with a word count after it specifying that this word has occured that number of times in the whole file.

today-->2
I-->3
have-->1
a-->3
lot-->1
write-->1
but-->1
will-->1
not-->1


and so on


I used tr to separate each word in a line but I'm not sure how I'm going to look for each word
