Post what you have attempted so far - someone may assist.....

and a gentle comment - when you have a title like "urgent" a lot of people will assume this is homework and you have a deadline - homework questions are frowned upon.....

better to have your title as a more descriptive staement of the actula problem - e.g. "trying to count occurences of words in inpout file in awk" or somesuch

Here is the command
grep -o "wordpattern" filename|wc -l

The following is my sample file

Code:

> cat file.txt
the angry person went to the store
to buy a new operating system as he saw
at the theatre a new and improved system
to handle all of the mundane tasks of
his boring job.

Now, after putting each word on its own line, grep for "the"

Code:

> tr " " "\n" <file.txt | grep "the" 
the
the
the
theatre
the

Notice the word "theatre" was selected. To correct for the, I use the -w option with grep as follows:

Code:

> tr " " "\n" <file.txt | grep -w "the" 
the
the
the
the

And finally, output a count

Code:

> tr " " "\n" <file.txt | grep -w "the" | wc -l
4

That's Useless Use of wc -l

" -c " option of grep would do that

Code:

tr " " "\n" <file.txt | grep -cw "the"
