All linx users, their passwords and other details are stored in a one file. It is " passwd " file which is in the "etc" folder. { /etc/passwd }             If we want to view password file {hm... there are several ways, but for the moment we will use "cat" command}.we will talk about "cat" command later. So in your command prompt {shell,terminal} run below command.  cat /etc/passwd This command will give you a file with several rows. One row is for one user. Let have a look on one row.  melick:x:1000:1000:melickrajee:/home/melick:/bin/bash  So let see what this line says.
