Motivation - Why Use SAS On Unix/Linux?Using SAS on UNIX/Linux Platformo Company migrating to UNIX/Linuxo Joining a company which is using SAS on the Linux platformChallengeToo many commands to learn!Why Use SAS On Unix/Linuxo Customising Linux sessions will ensure you increase work efficiency by takingadvantage of the imbedded Linux tools. In general transferring and running large fileswill be quicker in Linux compared to PC*.

TerminalWhat to expect when you login?% pwd/home/username% lsCustomise: Update .bashrc file with this line PS1 ' IV PWD EE ' will change your prompt to show thefollowing:/home/username

Terminal useful commandsHow do you find out if a version of a file has changed?/home/username diff file1.txt file2.txtCommand to compare two files.This is useful to compare outputs that have been re-run with an olderversion. This will compare line by line, hence it’s only useful tocompare different versions of the same file. This command cannotbe used to compare datasets.

Terminal useful commandsHow do I search for text in multiple files?/home/username grep -i string filename How do I run SAS in non-interactive mode/batch?/home/username sas filename How do I run code that is resource intensive?/home/username sas –memsize max mysascode.sas

Editing SAS filesHow do I edit SAS files?Linux editors for plain text can be divided into twocategories:1. Console text editors- include emacs, jed, nano, picoand vim.2. Graphical GUI editors - include gvim, gEDIT, Nedit,Slick edit, Tea and SublimeThe advantage of the GUI editor is intuitive user friendly interface while thebenefit of the console text editor is the suitability over long distancenetwork connections which may or may not provide suitable bandwidthor reliability which would both be required by the GUI editors for remoteoperation. Console based text editors. GUI editors Face to face meetingor teleconference.

What to look out for?LINUX platform is case sensitive and file directories and external filenames called within SAS are case sensitive but the SAS session isnot.Code written in PC SAS might not run on SAS because the MicrosoftWindows and Linux operating systems store text files in a differentformat. It is good practice convert a file from Microsoft Windows toLinux format by using a ‘dos2unix’ command on the terminal./home/username dos2unix mysascode.sas

Still other thingsOther things to keep in mindUse the ‘&’ at the end of Linux commands. This means thecommand will be executed in the background and you cancontinue using the terminal. Otherwise you will have to waitfor the command to execute before you can use the terminal.If you have a 3-button mouse you can copy text by highlightingthe text using your mouse. This automatically copies the textand you can paste the text by pressing down the wheel on themouse.

Terminal helpIf in doubt man it!!!Type man or fman command to access the system's reference manuals. It can beused to search for occurrences of specific text and other useful functions.

ALL ABOUT GUI/home/username sas&

Changing default behaviorSelecting and copying text

Changing default behaviorTruncation of inserted text?Text is not split at the cursor when you press ENTER or RETURN?I cannot use PC shortcuts to copy and paste texts?Modify the entries in the SAS: KEYS window

Changing default behavior

Remember my configuration settings?

CONCLUSION§ This presentation gives the basis for a lesspainful transition to using SAS on Linuxfrom PC.o There is greater flexibility in using Linux and the readeris encouraged to explore this in more detail to increasetheir productivity when using SAS on Linux.
