Let’s talk about links – what are those anyway?
Link is a pointer to a file or a directory. If you are not a programmer, a pointer is exactly what its name says it is – it is used for pointing to something. Let’s look at the following situation:
mislav@mislavovo-racunalo:~/Linux_folder$ ls -l
-rw-r--r-- 1 mislav mislav 8 Feb 5 23:09 1264.txt
-rw-r--r-- 1 mislav mislav 8 Feb 5 23:06 1-4.txt~
-rw-r--r-- 1 mislav mislav 8 Feb 5 23:06 2345.txt
The number in the second column (after file permissions) is the link count. Why is this link count number equal to 1 for these files? Because the only link that exists at this time is the link which is pointing from
Linux_folder to the file.
You can increase the number of links to a file and there are two types of links – only one type of link increases the link count. But that’s a topic for another article.
