====== Commands for Lab ======


===== Submitting Your Code Electronically to Your Turnin Directory =====


If you have your directories set up appropriately (i.e., your ''lab'' directory is in your ''cs111'' directory), you should be able to run

  turnin labx

where ''labx'' is the name of the lab you are submitting.  Using this command will ensure that all your permissions are set up appropriately.


If you want to know what's going on behind the hood, you could run this command from your ''cs111'' directory:

  cp -r labx /csci/courses/coursename/turnin/username
  
where ''labx'' is the directory of the lab you want to copy, ''coursename'' is your course name, and ''username'' is your username.
===== Creating Printable Files =====

To create a condensed, printable file of your lab, use the ''createPrintableLab'' command.

The syntax of the command is

  createPrintableLab <path_to_lab_directory>
  
For example, if you're in your ''labs'' directory, to print lab1, you'd write

  createPrintableLab lab1
  
will generate a file called ''lab1.ps'' containing all the printable files in your directory, not including subdirectories.  

==== Errors ====

If your directory contains unprintable files, like binary files (e.g., .pyc or image files), you'll see an error message about unknown or special characters.  Remove those files and run the command again.




===== Viewing a PS File: evince =====

To view a file, use the ''evince'' command.  

  evince postscriptfile.ps &

where ''postscriptfile.ps'' is the name of the file that you want evince to open.

For example

  evince lab1.ps &
  
Use the ''&'' to run the command in the background and continue to have use of your terminal.

If you can't use the terminal again, you probably need to close ''evince''.



===== Printing Files =====

To print from the command-line, you can use the ''lpr'' command.  **Do not try to print PDF files or images this way.**  The syntax of the print command is 

  lpr -P<printername> filename

For example:
  lpr -Pcslab test.ps
  
The printer name is ''cslab'' when you're in P405 or ''advlab'' if you're in P413.


The command ''lpr'' means to print the file. The option 'P' says which printer to use (one of the CS lab printers), and the argument says which file to print--in this case ''test.ps''.
