Linux — A- Z
Linux is an Open source Operating system developed by Linus Torvalds in 1991. It’s not UNIX but it is just like the Unix Operating system. To know about it one must have a look at Unix Architecture and understand how a new kernel was built. In Linux, there is no difference between files and directories. In other words, they are the same.
There are two types of users in Linux —
At the top level, a single drive is present and it is denoted with the help of ( / ) slash. In other words, it represents the root directory. There can be a number of directory underneath root directory —
It looks like a tree structure in terms of the file system. so we can say that:
- Root bin and Root usr bin directories contain regular user command lists.
2. Root sbin and Root usr sbin directories contain a superuser command list.
*All Commands are lowercase. We can also set the limit for the number of failed logins.
For example, [guest@lab5~]$_
This represents that the user is present in the home directory. The above prompt is displayed upon successful login.
Notation for the type of user —
- $- Regular user
- #- Super User
*Superuser is the root user.
*All the user’s directory is stored in root directory. If two users are logged into and using their home directory, the memory areas of the users are different in terms of workspaces.
The Super User Commands —
- [guest@lab5~]$ date : To display system date and time.
- [guest@lab5~]$ ls : To view or display all the files, directories present in the current directory. ls Stands for the list.
- [guest@lab5~]$ ls-l : Used to differentiate between directory name or file name.
4. [guest@lab5~]$ ls-a : -a represent hidden file list.
