echo - Displays command line arguments.
echo
echo [ <string>... ]
The echo utility writes its arguments, separated by blanks
and terminated by a newline, to the standard output. If
there are no arguments, only the newline character will be
written.
echo is useful within scripts such as /etc/rc to display
text to the console.
To mark the beginning or end of some scripted operation,
include echo commands like these in the script that
controls the sequence of commands to be executed on the
node:
echo Start the operation...
:
(do the operation)
:
echo Stop the operation.
When this sequence is executed, the following will be
displayed on the console:
Start the operation...
:
(other console output)
:
Stop the operation.
