<h2>First, what is a path?</h2>
|

</div>
|
||||
|
||||
|
||||
<div class= "text1">
|
||||
A path is a location to a folder or file in a file system of a Operating System, then is a combination of characters and "/"
|
||||
</div>
|
||||
|
||||
|
||||
|
||||
|
||||
<div class = "title3">
|
||||
<h3>Now, I can tell you what is an absolute path</h3>
|
||||
</div>
|
||||
|
||||
|
||||
<div class= "text2">
|
||||
An absolute path is defined as specifying the location of a file or directory from the root directory(/).
|
||||
In other words we can say absolute path is a complete path from start of actual filesystem from / directory.
|
||||
</div>
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
<div class = "title4">
|
||||
<h4>To write an absolute path-name:</h4>
|
||||
</div>
|
||||
|
||||
|
||||
<div class= "text3">
|
||||
Start at the root directory ( / ) and work down.
|
||||
<br>Write a slash ( / ) after every directory name (last one is optional)
|
||||
</div>
|
||||
|
||||
|
||||
|
||||
<div class = "title5">
|
||||
<h5>Example:</h5>
|
||||
</div>
|
||||
|
||||
|
||||
<div class= "text4">
|
||||
<p> cat group1.txt </p>
|
||||
if for example, we use the above line, this commands work only and only if the "group1.txt" exist in the current directory.
|
||||
<br> If not works, it's not a problem, the file is present somewhere, before restart the new command, you have to know where
|
||||
<br> the file is saved.
|
||||
<br> Now, we supposed that you know where your file is saved you can rewrite the command.
|
||||
<p1> cat /home/a1/group1.txt </p1>
|
||||
Now, we suppose that the file is saved into folder a1 in home,
|
||||
<br>where: /home is the location respect to root, in fact, you have to descend one level
|
||||
<br>in the file system like above to access your file.
|
||||
|
||||
As you can see from the last commands, all the paths started from /directory whis is a root directory for every Unix machines.
|
||||
|
||||
|
||||
<p2> Other examples, where all are absolute path </p2>
|
||||
|
||||
|
||||
/home/user/Document/group1.txt
|
||||
/root/data/dev.jpg
|
||||
/var/log/messages
|
||||
</div>
|
||||
|
||||
|
||||
<div class = "title6">
|
||||
<h5>Example of Absolute path's uses:</h5>
|
||||
Now, as we learned from the previous pages we can use other commands in addition to "cat", such as:
|
||||
<br> chmod
|
||||
<br> ls
|
||||
<br> mv
|
||||
<br> get
|
||||
<br> text
|
||||
<br> rm
|
||||
and so on.. with the sintax like above.

<h1>Relative Path!</h1>
|
||||
</div>
|
||||
|
||||
|
||||
|
||||
<div class= "text1">
|
||||
Relative path is defined as path related to the present working directory(pwd).
|
||||
<br>Suppose I am located in /home/user1 and I want to change directory to /home/user1/Documents.
|
||||
<br>I can use relative path concept to change directory to Documents.
|
||||
<br> <br> <br> <p> pwd/home/user1cd Documents </p>
|
||||
</div>
|
||||
|
||||
<br> <br> <br> Then you could tell me what is the difference between Absolute and Relative.
|
||||
|
||||
<br> If you observe, there is a little bit difference, where in relative there is no "/".
|
||||
<br> Meanwhyle using absolute path you have to write "/", in this case cd /home/user1/Documents.

|

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.
