Unix and Samba By: IC Labs (Raj Kidambi)

What is Unix?  Unix stands for UNiplexed Information and Computing System. (It was originally spelled "Unics.")  Unix now covers a whole host of variations or “flavors”, including Linux, FreeBSD, and Solaris.

Common Unix Commands  ls - list files in a directory syntax: ls [options] [names]  cd - change directory syntax: cd [dir]  mv - moves or renames a file or directory syntax: mv [options] sources target  rm - removes a file syntax: rm [options] [files]  rm -ir - removes a directory

Unix Commands  mkdir - creates new directory syntax: mkdir [options] directories  exit - allows you to log out of your host  date - prints the current date and time  cal prints the 1997 calendar  whoami - prints who is currently logged on to your terminal.

Unix Commands  mail - brings up a simple mail editor  pwd - tells you where you are; it prints the full pathname of the current directory  If you want more details about a particular command, you can check out the Unix main page, which is basically just a manual for Unix. The command for the manual is man.To quit man, type q.

Text Editors – vi The most commonly available text editor is vi (pronounced vee-eye), which I especially recommend for Mac users. You really only need to know a few commands to get started.vi  To start vi, simply type vi at the command prompt. The thing about vi is that you have to tell it when you're adding and deleting text. You can't simply type and delete, you have to use the following commands:

Vi Commands  To add text - hit the esc key and the letter i (for insert)  To delete text - hit the esc key and the letter x (for delete)  To delete an entire line - hit the esc key and the letters dd  To save your file - hit the esc key and type :w and then hit return  To save and exit vi - hit the esc key and type :wq and hit return

Other Editors  EMACS  Pico

Samba By IC Labs (Raj Kidambi)

What is Samba  Samba is an Open Source/Free Software suite that provides seamless file and print services to SMB/CIFS clients. Samba is freely available under the GNU General Public License. ( SourceFree SoftwareGNU General Public Licensehttp://us4.samba.org/samba/samba.html What the above technical jargon means is that Samba is a free software that lets you view your Unix Account in an Explorer like Interface enabling you to Drag/Drop from one to another and/or Print.

Uses of Samba  Create, Edit and save documents directly to your account.  Drag and Drop Files  Avoid the use of FTP

Launching Samba  Click on Start -> Programs -> The Internet -> Map Shell Account. This should launch Samba.

Logging into Samba  PLEASE REMEMBER: If your User ID is your Gateway ID, then if you changed your gateway password your Unix/Samba password will still be in the old format, i.e. year/day/ssn.  Enter your User ID and your Password, if you do not know your User ID and password then you can ask the IC Lab employees and they can further assist you.  After you connect into Samba it should open up an Explorer Window with a Title of “J:\”

Using Samba  Once you are logged into your account you can drag and drop from your account to the desktop and vice versa.  When you are done working with Samba, PLEASE remember to CLOSE the window first and then hit Disconnect.

Remember – Security  Remember to DISCONNECT after completing your work, otherwise someone may tamper with your files.  You will be automatically disconnected from Samba if your computer reboots, or crashed, so please SAVE your WORK often.
