<h1>Hard and Symbolic links</h1>
|
||||
|
||||
<p>In Unix-like operating systems such as Linux, “everything is a file” and a file
|
||||
is fundamentally a link to an inode (a data structure that stores everything about a
|
||||
file apart from its name and actual content).
|
||||
A hard link is a file that points to the same underlying inode, as another file.
|
||||
In case you delete one file, it removes one link to the underlying inode. Whereas a
|
||||
symbolic link (also known as soft link) is a link to another filename in the filesystem.
|
||||
Another important difference between the two types of links is that hard links can only
|
||||
work within the same filesystem while symbolic links can go across different filesystems.

<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.

<h1>Absolute Path!</h1>
|
||||
|
||||
<h2>First, what is a path?</h2>
|
||||
|
||||
<p>
|
||||
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 "/"
|
||||
</p>
|
||||
|
||||
<h3>Now, I can tell you what is an absolute path</h3>
|
||||
|
||||
<p>
|
||||
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.
