This reference card, obviously, cannot describe all UNIX commands in details, but instead I picked commands that are useful and interesting from a user's point of view. cat filename display the content of file filename cd [dirname] change directory to dirname. env print or alter environment variables hostname display host name man topic screen uname users w display on-line manual on topic. asWedit axe ee elvis HTML editor a simple X window text editor easy edit: emacs with a help menu a vi clone emacs jed start emacs. unix If at any time you want to change your password, use the command passwd and follow the process illustrated here. Examples of file names and some common extensions are listed below: stuff.txt view.Z program.c program.p data.dat (TeXT file) (compressed file) (C source file) (Pascal source file) (DATa file) Unlike OpenVMS, UNIX does not automatically keep older versions of the files. where filename is the name of the file you want to create. By using the -o option, the compiler can be forced to save the executable program with another name. The following line tells the compiler to compile the Pascal source file named homework.p and create an executable called homework. IntroToSCOUNIXSystems UNIX Systems, command, SCO UNIX Systems, shell, printing, environments, Process Control, security, features, home directories, operating system, Course Topics. This course is designed for system administrators who are new to the UNIX operating system, and for end users who work with SCO UNIX Systems in business, scientific, engineering, or home work environments. In this course, you will learn to accomplish basic tasks such as creating, organising and removing files, using text editors, printing and monitoring their processes. You will learn to accomplish these tasks through a command line interface. This course provides a technical overview of SCO UNIX System through task-oriented lectures and handson labs. UNIX_guide command, permissions, chmod, display, kill, formats, pathname, handy, grep, searching, owner, specify. This command is key to moving around your file structure. Structure: cd [name of directory you want to move to] When changing directories, start with / and then type the complete file path, like so: cd /webmonkey/chimp/ If you want to enter a subdirectory of the directory that you're currently in, then omit the first /. So if you wanted to stay in the chimp directory but move to the simian subdirectory, you'd type: cd simian/ chmod: Changing permissions on a file or directory chmod (which stands for "change mode") changes who can access a particular file. If one or more files are given, ls will display the files contained within "name" or list all the files with the same name as "name." Structure: ls [options] [names] ls is a command you'll end up using all the time. eq27 commands, Help Desk, Lists, quota, UNIX commands, OIT, filename, lynx, PDF, HTML, lpr, newfilename. Getting online help man command [return] Lists the manual pages for the specified command. Checking your quota quota [return] Compare the number in the current column to the one in the first quota column. Viewing a file on the screen more filename [return] Lists named file on screen one screen at a time. E and EQ documents are available on-line in electronic formats on the OIT On-line Help Desk. PDF documents can be printed by anyone from a computer with Netscape, Adobe Acrobat Reader, and a Postscript printer; or, they can be printed on request by the OIT Help Desk. unixbasics command, printers, lists, UNIX, queue, typing, renames, prompt, thels command, shell variables, print job, typeh. The UNIX operating system is case sensitive. Commands can include three parts: a command, an option, and an argument. The command man -k ls displays a list of man pages that pertain to thels command. Typehelp at a UNIX prompt for a list of topics, or typehelp topicname for information about a specific topic. For example,help mail would display items associated with using mail. Lists the contents of the current directory. Displays a list of available printers and their physical locations. For example,lprm -Pps_sal125 690 cancels print job 690 from the SAL printers' queue. The commandset displays the current value of all shell variables.
