total number of files which have "aaa" in files whose names are File*_bbb*

I am getting the list of all the files which have "aaa" from files whose name is File*_bbb*.

grep -l "aaa" File*_bbb*

But I want to count the number of files. That is I want the total number of files which have "aaa" in
files File*_bbb*

If I run the following for getting number of files, I am getting 0 files returned.
grep "aaa" File*_bbb* | wc -l

So how do I get the total number of files which have "aaa" in files whose names are File*_bbb*

Try this:

grep -l "aaa" File*_bbb* | wc -l

If your last command
grep "aaa" File*_bbb* | wc -l

returns 0, it means that there are no occurrences of the pattern "aaa" in all the searched files (File*_bbb*). In any case, the result of this command is not what you want, because if in a file the pattern is matched more than once, you will have the count of ALL the occurrences and not the count of the files which contains the pattern.
