Lab 1 and Lab 2: Unix Tutorial
Lab 1 and Lab 2:
Unix Tutorial

  1. Setup accounts : for both CS-NT and CSA. You need the CS-NT account to log into CS NT, and CSA accout is required to log into CSA server.
  2. Unix account: Important softwares that allow you to access your unix account from a window machine (such as Putty, CRT, XWin) can be downloaded from PCSC . The host name is csa.bu.edu if you need to log into CSA unix server.
  3. csmail - Every computer science class has its own mailing list. To join one, type csmail -a csXXX (e.g. csmail -a cs101b1) at the prompt. To remove yourself from a mailing list, use the -r option instead (i.e. csmail -r cs101b1).
  4. web-ok - Set up your home page on csa. You have to use this command for the future labs.
  5. pine - Start the unix emailing software.
  6. mkdir directoryname - make a directory
  7. mv file_or_directoryname - move a file or a directory.
  8. cp filename_or_directoryname - copy a file (copy -r to copy a directory and all files and subdirectories inside it recursively).
  9. rm file_or_directoryname - remove a file (rm -r to remove a directory and all files and subdirectories inside it recursively).
  10. pico filename - a notepad-like editing software.
  11. cat filename - list the content of a file till the end of the file
  12. less filename - list the content of a file. You can use arrow key to move forward and backward. Strike q key to quit.
  13. cd directoryname - to return to your home directory, cd some_dir to go inside a directory named "some_dir".
  14. ls - list the content of the current directory (-l to list the details, -a to show hidden files).
  15. pwd - list the path of the current directory.
  16. chmod xxx_code filename_or_directoryname - change permission. A file permission is a 3 8-bit numbers indicating how the file could be accessed by whom. The first number applies to the owner, second to the group (e.g. ugrad), third to public (i.e. everybody). An 8-bit number could be represented by a three digit binary number in a format of "rwx" where r is read permission, w is write permission, and x is execution permission. x permission on a directory is neccessary for access, and any file with any x permission on will have a "*" next to it when "ls"ed to indicate that it is an executable file. For example, binary number "110" (2^2*1+2^1*1+2^0*0) is equal to 6 which represents read and write permission. Most of the case, you would want to set a public file (e.g. html file) 644 so you can edit it and everyone can read. A public directory should set to 755 so people can access it. Avoid setting anything to 777 or anyone could write and delete that particular file/directory.
  17. finger - finger -l login@cs.bu.edu to retrieve the information of a particular user specified by 'login'.
  18. history - list out your previous commands entered at the prompt.
  19. man -- You can consult the manpage or help manual of a command using "man" or "-help" option (e.g. man chmod, csmail -help).
