Print a string to the current output device.
echo [--nonewline] [string]
| Option | Description |
|---|---|
string |
The string to print. |
-n, --nonewline |
Supress printing of the newline character |
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.
This example will add these comments to the screen and any open log file.
