<h3>Redirecting Outputs</h3>
|
|
<p>First of all, to redirect a certain output of the command-line we have to use the symbol ">".</p>
|
|
<p>Even in this case, we will use a file named "Hello", in which we want to move a certain output, like "Sun".</p>
|
|
<hr>
|
|
<p>$ echo Sun > Hello </p>
|
|
<p>So if we copy the the file on our command-line, the output will be the following:</p>
|
|
<p>$ cat Hello<br>
|
|
Sun</p>
|
|
<hr>
|
|
<br>
|
|
<p>If we want to move a certain output to an existing file, we just have to use twice the ">" symbol.</p>
|
|
<hr>
|
|
<p>$ echo Bright >> Hello</p>
|
|
<p>$ cat Hello<br>
|
|
Sun<br>
|
|
Bright</p>
|
|
<hr>
|
|
<br>

<h3>Redirecting Inputs</h3>
|
|
<p>To redirect an input from a file for a command, you have to use symbol "<".<br>
|
|
In fact, it's not useful, as the result that obtain is just the content of the file.</p>
|
|
<p>Redirecting inputs becomes useful when it comes to chaining, so let's see it.<p/>
