<h1>ABSOLUTE VS RELATIVE</h1>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
Now, you can ask, why I have to use one or another?
|
||
|
|
<br> What is the difference? and questions like this.
|
||
|
|
<br> <br> <br> Don't worry, the answer it's easy.., we can use an absolute path from any location
|
||
|
|
<br> whereas you want to use relative path we should be present that you have to be in the working directory.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
|
||
|
|
<br><br><br>We suppose that now you know the differences between both, but, what is the vantages and disadvantages?
|

<h3> Pro and Cons of using Absolute and Relative </h3>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
<br>1)Absolute paths are clearer: who will have to maintain/modify your script (you or others) will be able to know
|
||
|
|
<br>every time what directories are involved;
|
||
|
|
<br><br>2)With absolute paths you are sure the involved directories are the one with the exact path you are writing
|
||
|
|
<br>in the script;
|
||
|
|
<br><br>3)Relative paths are shorter, but you need to be sure of the subtree you're working into;
|
||
|
|
<br><br>4)You can achieve shortness replacing recurring paths with a variable at the beginning of the script
|
||
|
|
<br><br>
|
||
|
|
(e.g. /var/log/app/component/module/logfile.log -> $module_log_dir/logfile.log)
|
||
|
|
|
||
|
|
|
||
|
|

<h3> I'm sure that if you read this for two or more times you will be able to pass the quiz </h3>
|
||
|
|
|
||
|
|
Yeah, right, there is a quiz.
|
||
|
|
<br> The best way to learn something it's not the theory, in fact you have to do some practice, if you click
|
||
|
|
<br> the button "QUIZ", you can try to do a quiz in order to check what you've just read.
|
||
|
|
|
||
|
|
<br><br><br> Don't worry it's for you, good luck
|
||
|
|
|
||
|
|
|
||
|
|
<br><br><br> * for css, please try to do a button or layout to links the quiz*
