How to display the first 5 bytes?

To display the first 5 bytes of a file in a Unix-like operating system, you can use the head command with the -c option. Here’s how to do it:

Command:

head -c5 /tmp/hello

Breakdown:

• head: This command outputs the beginning of a file.
• -c5: This option specifies that the first 5 bytes should be displayed.
• /tmp/hello: This is the path to the file you want to read.

Example Output:

If the file hello contains:

Hello, World!

Running the command will output:

Hello

This command is useful for quickly checking the first few bytes of a file. If you have any further questions, feel free to ask!
