UNIX for Dummies Questions & Answers

I have a program which I am trying to improve and I hope you can help me
1 ) My main program took a file and list of words such as [the, and, is, that, there]
2) Created a matrix of the patter of 2 by 2s of instances where one word was followed by the other word.
3) Save each pattern in a file
So having a list like

The I would have files such as

For this I was using the following lines

Code:

For X (the list of the words)
	For Y ( the list of the words)
		grep -o "$X .* $Y " test01.txt  > data/$X-$Y.txt
	done
done

now I want to create a pattern of Three but I tried adding Z to it but it didn't work and I don't know what I am doing wrong

Code:

For X (the list of the words)
	For Y ( the list of the same words)
		For Z (the list of the same words)
			grep -o "$X .* $Y .*$Z " test01.txt  > data/$X-$Y-$Z.txt
		done
	done
done

so the outcome should have a result like


I would really appreciate any help

Can you post a sample input file(test01.txt) and a sample of what the (the list of the words) would actually look like in the code:

Code:

for x (the list of the words)
  for y (the list of the same words)
    for z (the list of the same words)
      grep -o "$X .* $Y .*$Z " test01.txt  > data/$X-$Y-$Z.txt
    done
  done
done

I have no specific file or list of words yet but the concept is to see the pattern of things like words that come together or within small distance. For example “strategic business managements” is more likely than “strategic engineering management”

I am testing now on simple texts. Here I attached some lines from a novel (test 01.txt) and put the list as [the be to of and] as they are more frequent and it will help me to see any pattern. Test02 is windows of 10 starting with the list within a sentence and that’s the input for seeing the pattern
And the final result of all of this is


hope that does make sense.
I have done the same with two words with the code mentioned above and its file but not sure how y it is not working when I add another FOR

I have solved the Issue and it was a syntax error. the line should be corrected with the right lines and breaks otherwise the whole page will be considered as a line
I am still facing some problems but it is related to the loop and not the GREP so I guess I have to ask it in another thread
