Counting Commented lines in code

[aparajita]

In Pl/SQL scripts, The comments are multi lined starting from /* and ending with */.
How can we count the commented lines if there are hundred scripts to be scanned.
a grep command will give only the first and last line.

Are you looking at counting total number of commented lines from a file?

yes, i am looking at counting total no of lines in a code which are commented but not from a single file...it has to be done for abt 100 PL/SQL codes....

Try this:

1. Have a counter = 0
2. Loop through the file, read line by line and grep for /* or *\. Say /* is in 6th Line. Then here counter = 6. Assign this calue to another variable say start_of_line = 6
3. Then cotinue fetching and checking for /* or *\. If you find *\ in 10th line. Now counter = 10, now result=result + (counter - start_of_line));
So result = 0 + (10-6) => 4;
4. Continue for another set of lines in the loop and keep adding to the result. Finally when you reach END OF FILE, you will have the total number of lines in the PLSQL CODE.

Try implementing this logic and let us know in case of any issues.

If you want only the sum of total count from all the files as such, then i suggest you to concatenate all the files in to a single one and then loop through a single file. If you want the count file wise, then you need to loop through the files individually.

Yes, this is an option but using 'sed' to count the commented lines gives quite good results :)

Thats Good!! I dont have a unix box here else I would have tried and checked it out!!
