Linux directories and file folder permission basic

You are most welcome to this post.

Really thanks to you for your interest in this topics. :)

Now we are going to have some discussion about the directories and the file folder permission basic. In the linux OS, you need to log in as a super user to chane the file folder permission

[root@localhost ~]# cd /

[root@localhost /]# ls

 

Lets have some knowledge about them:

 

Bin – binary file of user.

Boot – system boot related file.

Dev – system device file.

Etc – configuration file of all server.

Home – home dir of regular user.

Lib – File location of system library. The files needed to execute, located in /in and /sbin.

Media – Default mount point of system.

Mnt – mount point.

Opt – this is indicated as optional point.

Proc – System process related info (CPU, RAM, Processor etc.) is located here.

Root – the home directory of root user.

Run – Running data of service.

Sbin – root user system binary

Sys – Generally known as system.

Tmp – temporary files (Generally deleted after 10 years)

Usr – Installation location of third party software.
