How to specify exact byte counts?

To specify exact byte counts in the head command, use the -c option followed by the exact number of bytes you want to display. Here’s the syntax:

head -c [number_of_bytes] /path/to/file.txt

Example:

If you want to display the first 100 bytes of a file named example.txt, you would run:

head -c 100 example.txt

This command will output exactly the first 100 bytes from example.txt. You can replace 100 with any other integer to display that specific number of bytes.
