I do not believe that grep has a -exec option. This looks like the end of a find command.
Using the * to specify all files might hit problems if:-
There are too many files and your expanded command exceeds the limit
There are special files, such as directories etc.
If the string you are looking for is /klp/ then you may need to consider that the / is a special character. You might need to search for \/klp\/ to get what you want.
I would use find to generate the list to work with and then for each file you find, you could use grep, sed or perhaps awk to make the edit depending how you want the edit to affect the file.
I would suggest initially that you should use this to select the files to work on:-
I would avoid running the ls -l as you will only have to extract the file again information later on.
The use of /dev/null causes grep to output the filename and when combined with the -l flag does not show you the actual matching lines.
From this list, you can then decide what to do next. Do you want to:-
Delete the whole record where the string is matched
Delete just the actual string matched
Overwrite the actual string matched (in case you have fixed width data)
