  • Lab Intro to Console Commands
    New Lab Intro to KDE Terminal Konsole After completing this lab activity the student will be able to; Access the KDE Terminal Konsole and enter basic commands. Enter commands using a typical command line interface (CLI). Explain the use of the following commands, ls, ls –al, dir, mkdir, whoami, Explain the directory structure of a typical user. This lab activity will introduce you to one of the many command line interfaces available in Linux/UNIX operating systems and a few of the most basic commands. The command line interface you will be using for this lab activity is the console called the Konsole and is also referred to as Terminal. Note: As you notice, in the KDE system many features are written with the capital letter “K” in place of the first letter or the utility to reflect the fact it was modified for the KDE system. The original UNIX system did not use a graphical user interface GUI but rather was a command line interface (CLI) similar to the command prompt in Windows operating systems. The command line interface is referred to as a shell. Even today the command line interface (the shell) is used to issue commands on a Linux server to minimize system resources. For example, there is no need to start the GUI on the server to add a new user to an existing system. Starting the GUI will reduce the system performance because it requires RAM to run the GUI. A GUI will affect the overall performance of the server when it is supporting many users (clients).

  • Bash Tutorial
    Bash Shell Lecturer: Prof. Andrzej (AJ) Bieszczad Email: [email protected] Phone: 818-677-4954 Bash Shell The shell of Linux • Linux has a variety of different shells: – Bourne shell (sh), C shell (csh), Korn shell (ksh), TC shell (tcsh), Bour ne Again shell (bash). • Certainly the most popular shell is “bash”. Bash is an sh- compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). • It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard. • It offers functional improvements over sh for both programming and interactive use. Bash Shell Programming or Scripting ? • bash is not only an excellent command line shell, but a scripting language in itself. Shell scripting allows us to use the shell's abilities and to automate a lot of tasks that would otherwise require a lot of commands. • Difference between programming and scripting languages: – Programming languages are generally a lot more powerful and a lot faster than scriptin g languages. Programming languages generally start from source code and are compil ed into an executable. This executable is not easily ported into different operating syste ms. – A scripting language also starts from source code, but is not compiled into an executabl e. Rather, an interpreter reads the instructions in the source file and executes each inst ruction. Interpreted programs are generally slower than compiled programs. The main a dvantage is that you can easily port the source file to any operating system. bash is a s cripting language. Other examples of scripting languages are Perl, Lisp, and Tcl.
