You can do many things with
echo, especially with redirection (see below for more about redirecting output). In its simplest use,
echo sends whatever you tell it to send to standard output. If you want to repeat text on the screen (useful in a shell script, for example), you would enter the text string in ' marks and see the output below it, like this:
matthew@seymour:~$ echo 'I have the power!'I have the power!
If you want to know the value of a system variable, say TERM, you can enter the variable name and the value will be output, like this:
matthew@seymour:~$ echo $TERMxterm
