Please try the following, assuming it runs on your system:

Code:

$ cat file1
word1
word2
word3

$ cat file2
word1
word2 word3
word2 word3 word3 word4

Code:

$ cat temp.sh
grep -f file1 file2 > good_lines
sed "s/\<[a-zA-Z0-9_]\+\>/&\n/g" good_lines > split_lines
grep -f file1 split_lines | sed "s/^ *//; s/ *$//" > matched_words
sort matched_words | uniq -c

Code:

$ ./temp.sh
      1 word1
      2 word2
      3 word3

I defined a "Word" as the standard [a-zA-Z0-9_].
So this includes "Words" with numbers and underscores.
Alternatively, you could use [a-zA-Z].
Or maybe you want to count "auto-correct" as one word.
In that case, [a-zA-Z-] would work.

The standard word you defined is great as it is.

I created the temp script but it did not work as expected in one of my systems

Code:

 $ ./temp.sh
sed: Function s/\<[a-zA-Z0-9_]\+\>/& cannot be parsed.

I'm not sure why some sed functions are not functioning/installed here. Any ideas to circumvent this error?

However in my other system the result was as expected, so thanks a lot!

I was able to prevent the error by using single quotes instead of double quotes, still the result did not come right, see below:

Code:

$ ./temp.sh
   1 word1
   1 word2 word3
   1 word2 word3 word3 word4

This is the content of the file split_lines:

Code:

word1
word2 word3
word2 word3 word3 word4

Any ideas?
