Windows – alternatives to FastX ● Need ssh client - PuTTY ● http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html - XShell ● http://www.netsarang.com/download/down_xsh.html ● For X applications also need X-forwarding tool - Xming (use Mesa version as needed for some apps) ● http://www.straightrunning.com/XmingNotes/ - Make sure X forwarding enabled in your ssh client Linux or Mac Desktop ● Just need to open up a terminal or console ● When running applications with graphical interfaces, use ssh –Y or ssh –X Getting Started - Login ● Download and install FastX if you like (required on windows unless you already have PuTTY or Xshell installed) ● If you have a CHPC account: - ssh [email protected] ● If not get a username and password: - ssh [email protected] Shell Basics q A Shell is a program that is the interface between you and the operating system -
Shell Variables

The shell is the wrapper around the system: a communication means between the user and the system The shell is the manner in which the user can interact with the system through the terminal. The shell is also a script interpreter. The simplest script is a bunch of shell commands. Shell scripts are used in order to boot the system. The user can also write and execute shell scripts. Shell – p. 3/55 Shell - which shell? There are several kinds of shells. For example, bash (Bourne Again Shell), csh, tcsh, zsh, ksh (Korn Shell). The most important shell is bash, since it is available on almost every free Unix system. The Linux system scripts use bash. The default shell for the user is set in the /etc/passwd file. Here is a line out of this file for example: dana:x:500:500:Dana,,,:/home/dana:/bin/bash This line means that user dana uses bash (located on the system at /bin/bash) as her default shell. Shell – p. 4/55 Starting to work in another shell If Dana wishes to temporarily use another shell, she can simply call this shell from the command line: [dana@granada ˜]$ bash dana@granada:˜$ #In bash now dana@granada:˜$ exit [dana@granada ˜]$ bash dana@granada:˜$ #In bash now, going to hit ctrl D dana@granada:˜$ exit [dana@granada ˜]$ #In original shell now Shell – p. -
The Linux Command Line Presentation to Linux Users of Victoria
The Linux Command Line Presentation to Linux Users of Victoria Beginners Workshop August 18, 2012 http://levlafayette.com What Is The Command Line? 1.1 A text-based user interface that provides an environment to access the shell, which interfaces with the kernel, which is the lowest abstraction layer to system resources (e.g., processors, i/o). Examples would include CP/M, MS-DOS, various UNIX command line interfaces. 1.2 Linux is the kernel; GNU is a typical suite of commands, utilities, and applications. The Linux kernel may be accessed by many different shells e.g., the original UNIX shell (sh), the TENEX C shell (tcsh), Korn shell (ksh), and explored in this presentation, the Bourne-Again Shell (bash). 1.3 The command line interface can be contrasted with the graphic user interface (GUI). A GUI interface typically consists of window, icon, menu, pointing-device (WIMP) suite, which is popular among casual users. Examples include MS-Windows, or the X- Window system. 1.4 A critical difference worth noting is that in UNIX-derived systems (such as Linux and Mac OS), the GUI interface is an application launched from the command-line interface, whereas with operating systems like contemporary versions of MS-Windows, the GUI is core and the command prompt is a native MS-Windows application. Why Use The Command Line? 2.1 The command line uses significantly less resources to carry out the same task; it requires less processor power, less memory, less hard-disk etc. Thus, it is preferred on systems where performance is considered critical e.g., supercomputers and embedded systems. -

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). -
