echo (Shell Scripting)

Echo is the method of printing to standard output in a shell script. It accepts an unimited number of arguments, printing each one to the screen.

Standard Usage is:

#!/bin/bash

echo Cool Beans

The output from echo can be easily redirected into a file using the > operator:

#!/bin/bash

echo Cool Beans > MyCoolFile.txt

If you wanted to immediately trash the output, you can do so by redirecting the output to /dev/null

#!/bin/bash

echo This will not show up on the screen > /dev/null
