I have this folder contiaining a lot of *.cpp and *.h files. I want to get a line count of all the files and display them to the screen in sorted order of line count.
I know wc -l *.h *.cpp will display all the file names with line count, but not in sorted order.

The easiest way to count files in a directory on Linux is to use the “ls” command and pipe it with the “wc -l” command. The “wc” command is used on Linux in order to print the bytes, characters or newlines count. However, in this case, we are using this command to count the number of files in a directory.
The wc command is used to find the number of lines, characters, words, and bytes of a file. To find the number of lines using wc, we add the -l option. This will give us the total number of lines and the name of the file.
The ls command is used to list files or directories in Linux and other Unix-based operating systems. Just like you navigate in your File explorer or Finder with a GUI, the ls command allows you to list all files or directories in the current directory by default, and further interact with them via the command line.
Countings Millions of Lines of Files As an example, the Linux kernel has many directories, subdirectories, and thousand of files. In such a case, the find command splits the list of files into pieces and makes the wc command print a total for each sublist rather than a total for the entire list.
Use wc -l *.h *.cpp | sort -n. One job (sort), one tool (sort).
