OK, I will explain. There are numerous commands as you know and with the man page you can know about this command. So let us say, I type in man ls for example, or with an option man ls -l, and I get info about this command. Now what I want to do is this: I want to ask the program to tell me how many lines will the man page display about this specific command, in our example ls or with option ls -l. And then again ask about how many specific pair of letters come up in the man pages of this command. So using our example again (ls), I want to ask the programme how many of the letters lm appear in each line of the man pages of this command, for example. To sum up.

I want to know:
1. How many lines about a certain command appear in the man pages when I type man command or man comman -option.
2. How many pair of words appear in each line. So for example to know how many lm appear in each lien of this command in the man pages.

Hope it is a bit clear now. Sorry, if I didn't make it clear before!
