print - shell built-in function to output characters to the screen or window
SYNOPSIS

DESCRIPTION

-R
-r (raw mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than
-n.
-p causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output.
-s causes the arguments to be written onto the history file instead of standard output.
-u [ n ] flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1.
