Viewing File Content (cat, less, head, tail)

Ever wonder what's inside a file without opening a graphical editor? The Linux terminal provides powerful commands to quickly view file content.

This is super handy for checking log files, configuration settings, or just getting a quick peek at a document.

The cat command (short for 'concatenate') is one of the simplest ways to display the entire content of a file directly to your terminal screen.

Let's create a small file and then view it:

echo "Line 1\nLine 2\nLine 3" > my_file.txt

Now, run cat my_file.txt:

cat my_file.txt
Output:
Line 1
Line 2
Line 3
