Count lines of code across multiple file types, sorted by least amount of code to greatest

find . $ -iname '*.[ch]' -o -iname '*.php' -o -iname '*.pl' $ -exec wc -l {} + | sort -n

The same as the other two alternatives, but now less forking! Instead of using '\;' to mark the end of an -exec command in GNU find, you can simply use '+' and it'll run the command only once with all the files as arguments. This has two benefits over the xargs version: it's easier to read and spaces in the filesnames work automatically (no -print0). [Oh, and there's one less fork, if you care about such things. But, then again, one is equal to zero for sufficiently large values of zero.]

Count lines of code across multiple file types, sorted by least amount of code to greatest

Gives you a nice quick summary of how many lines each of your files is comprised of. (In this example, we just check .c, .h, .php and .pl). Since we just use wc -l to count, you'll just get a very rough estimate of how many lines of actual code there are. Use a more sophisticated algorithm instead if you need to. Show Sample Output
This is sample output - yours may be different.
```

22  ./helpers.h
35  ./gfx.h

find -exec is evil since it launches a process for each file. You get the total as a bonus. Also, without -n sort will sort by lexical order (that is 9 after 10).

What Others Think

Extremly useful information in order to understand coding, code across multiple files as well. I hope you will share some video tutorial on this topic in order to understand it well and cheap assignment writing service help students to complete their assignment work. Thank you!
