Description¶
This command echos the args to the current output stream. This is normally
stdout but can be set to a variety of channels. If an arg is --nonewline then
no newline is printed at the end of the printed strings. Otherwise a newline is
printed after printing all the given args. Echo is the easiest way to add user
comments or identification strings in a log file.
Example¶
This example will add these comments to the screen and any open log file.
