How to display last byte?

To display the last byte of a file in a Unix-like operating system, you can use the tail command with the -c option. Here’s how you can do it:

tail -c1 /tmp/hello

Breakdown of the Command:

• tail: This command is used to output the end of a file. By default, it shows the last 10 lines, but you can specify the number of bytes to display.

• -c1: This option specifies that you want to display the last 1 byte of the file.

• /tmp/hello: This is the path to the file you want to read.

Example Output:

If the last byte of the file /tmp/hello is !, the command will output:

!

Summary:

Using tail -c1 is an effective way to quickly check the last byte of a file. If you have any more questions or need further assistance, feel free to ask!
