--- layout: page author: Domenico Votta category-page: advanced category-title: Advanced commands tags: compare sorted files title: comm --- The comm is a command that compares two sorted files line by line and writes the output: the lines that are in common and the lines that are unique.
Here we have two files named example1.txt and example2.txt that contain 5 elements, to test this command:
example1.txt {% highlight bash linenos %} Icecream Chocolate Cake Candy Biscuit {% endhighlight %} example2.txt {% highlight bash linenos %} Bread Chocolate Tomato Candy Pizza {% endhighlight %} The syntax command is:
comm [flag][file1] [file2]
comm example1.txt example2.txt
    Icecream
        Chocolate
    Cake
      Tomato
        Candy
    Biscuit
      Pizza
