Sending a message to standard output

Use the echo command to display messages on the screen.

For example, to write a message to standard output, at the prompt, type the following:
echo Please insert diskette . . .
The following message is displayed:
Please insert diskette . . .
For example, to use the echo command with pattern-matching characters, at the prompt, type the following:
echo The back-up files are: *.bak

The system displays the message The back-up files are: followed by the file names in the current directory ending with .bak.
