Permissions in Linux

Hello friends in this blog post I am discussing about permissions in Linux system. We have faced more time problem of reading, writing, and executing problems because of permissions. That is the owner of the particular file sets the permission who can read, write and execute it. In this blog we are just understanding how combinations of permissions to file or directory. In Linux there is only one root and other are administrators and normal user who having limited access or permissions. root user having complete authority to operate Linux system who is highest authority in Linux system. Administrator have also highest authority but not much authority like root user.
