Using the "! no echo" Comment

To disable the echo command without the text "no echo" appearing in the script
output, use the commented no echo command as the first line in any script. A
script actually executes the commented command no echo. (If you are familiar
with MS-DOS batch files, this command is similar to the @echo off DOS
command.) For example, enter:
! no echo
echo "Hello"
The output is:
Hello
If you enter:
! Print Echo
echo "Hello"
The output is:
echo "Hello"Hello
This happens because the script tells the script engine to print the echo command
to the screen. The result is that the script engine prints the echo command and its
argument ("Hello") to the screen, followed by the output (Hello) of the command.
This is usually not a desired result, so you typically start most scripts with the !no
echo command as the first line.
