Out:= -graphics-), use Display to create the file output.eps in the directory you started Mathematica from. When the output of a command is graphics (i.e. To create an EPS file use the Disiplay command as shown in the following example. For general use (printing and use in other applications), the encapsulated postscript (EPS) format is recommended. Mathematica allows you to generate a number of different output file types. To print or save graphics output use the Display command to create an output file. Printing or Saving Graphics with Mathematica for UNIX Then type the command math at the UNIX prompt to start Mathematica in text mode or type the command mathematica to start Mathematica with the graphical notebook interface. Using this technique to check for drive existence depends on device driver implementation and may not always work.To use Mathematica on UNIX, first source the Mathematica setup file in a SSH program of your choice using the command: In the case of checking for drive existence, however, caveats exist:Īn Abort, Retry, Fail? error occurs if the drive is not formatted. This behavior is documented in a Microsoft knowledge base article ( ) and I have confirmed its behavior on FreeDOS 1.1 and in a Windows 7 command shell.ĮXTRA: The KB article indicates this technique can also be used to see if a drive is present. Checking for its existence is equivalent to a check for the directory's existence. It turns out that to support constructs like appending >NUL on command statements, there is a sort of virtual file named "NUL" in every directory. Fortunately, there is an obscure workaround: C:\> IF NOT EXIST C:\FOLDER\NUL ECHO C:\FOLDER missing.Ĭ:\> IF EXIST C:\FOLDER\NUL ECHO C:\FOLDER exists. The EXIST function returns the same result for both missing and present folders.
Unfortunately, the above does not work for directories. The solution when the resource is a file it is pretty straight-forward as indicated by others: C:\> IF EXIST C:\CONFIG.SYS ECHO C:\CONFIG.SYS exists.
