Look in linux there are man pages that give detailed discription of all command of linux and linux programming.

To get the number of files you have to read the directory. Go to console and write.

man scandir
This will show you how to read the directory.

Also check "man readdir". After reading directory you will get the list of files in a structure that you will pass to the function. Its **namelist and you can see the name of the file from namelist->d_name now you can open each file using open command and then get a line and print it.

Code:

#!/bin/sh

echo "There are `ls | wc -l` files in the directory."

for i in * ; do
  head -n1 $i
done
