The number of rows wc command to count the contents of the file, the number of words, the number of letters. But if you want to count the number of rows in a directory of all files, wc recursion does not provide statistics.
However, you can combine the find command, for example:
$ Wc -l `find -name * .c`
Wherein, -l parameter statistics the number of rows, find -name * .c is to find the current directory (including subdirectories) and all C files, `` is a shell replacement command.
Of course, there are many methods to achieve, I just think this is relatively simple and easy to remember.
Finally, with the use of what wc help (man wc)
