head:tldr:357b3

The command "head --bytes ${count} ${filename}" is used to display the first few bytes of a file.

Here is an explanation of each part of the command:

• "head" is the command itself, used to show the beginning of a file or input.
• "--bytes" is an option for the "head" command, specifying that we want to display a specific number of bytes.
• "${count}" is a placeholder for a variable that should be substituted with an actual number. You need to provide the desired number of bytes to be shown.
• "${filename}" is another placeholder for a variable that should be substituted with the actual name or path of the file you want to inspect.

For example, if you want to display the first 100 bytes of a file called "example.txt", the command would look like this: "head --bytes 100 example.txt".
