Study Notes
Operating System (OS)
- An operating system (OS) is the sum of all programs required to operate a computer.
- It is used to control and monitor application programs.
UNIX
- UNIX was originally written in the programming language C.
- It is mainly used for scientific-technical applications on mainframes and workstations.
- It can also be used for application in networks.
- UNIX is command-line oriented, but can be used via a graphical user interface.
Linux
- Linux is a family of UNIX-like open-source operating systems developed by Linus Torvalds.
- As an open-source operating system, instances of the Linux kernel can be used to form another operating system.
- A Linux distribution (distro) is a collection of software on top of a Linux kernel.
- A distro aims to provide a common look and feel, secure and easy software management, and often a specific operational purpose.
Linux Environment
- Shells are interfaces to the operating system, providing the necessary instructions and operations that an operating system may process.
- Shells can be in two forms: Graphical User Interface (GUI) and Command Line Interface (CLI).
- GUI is a graphical representation in which users can interact with software or devices through graphical icons.
- CLI is a console or text-based representation in which users type commands to operate software or devices.
Linux Desktop Environments (GUI)
- GNOME was once the most popular Linux desktop environment, simple and fairly lightweight.
- KDE is more complex than GNOME, packing in many more configuration options and features.
- Xfce is a more lightweight desktop environment, similar to GNOME.
- Cinnamon is a modern desktop environment, offering nice graphical effects and a rethought application menu.
Basic Linux Commands
- man: displays user manual of any command on the terminal.
- file: determines the type of a file.
- whatis: displays short descriptions of a program.
- whereis: locates files and pages of a command.
- whoami: displays the current user.
- ls: displays the list of files and directory.
- tree: displays the contents of the working directory recursively.
- pwd: displays the current directory.
- cd: changes the current directory.
File Management and Structure
- All files are organized into directories, which are organized into a tree-like structure called the filesystem.
- There are three basic types of files: Ordinary Files, Directories, and Special Files.
- Linux directories:
- /: root directory
- /bin: contains binaries
- /boot: contains files required for starting the system
- /dev: contains device files
- /etc: dumping ground for system files
- /home: contains users' personal directories
- /lib: contains libraries
- /opt: often used for compiled software
- /proc: virtual directory containing information about the computer
- /sbin: contains applications for the superuser
- /usr: contains a mish-mash of directories and files
