lp: Print the output of a command to the default printer (see `lpstat` command).
$ echo "test" | lp
try on your machine
This command is a simple example of using shell redirection.
The echo command is used to display a specified string on the terminal. In this case, the string being displayed is "test".
The | symbol is known as a pipe and it is used for redirecting the output of one command to another command. In this case, it is redirecting the output of the echo command to the lp command.
The lp command is used to print files. By using this command after the pipe, it takes the output of the echo command ("test") and sends it as input to the lp command, resulting in "test" being sent to the printer for printing.
