Mathbg
Use mathbg to run a Mathematica script in the background.
Name the file of commands to be read, and the new file to which results should be written.
The script is a convenient way to unsetenv DISPLAY and then run the lengthier command
nohup nice math -noinit -batchinput -batchoutput < commandfile > resultsfile &
plus give a tip about ``ps jobnumber''.
newton> mathbg USAGE: mathbg commandfile resultsfile This script runs your Mathematica commandfile in the background, at a 'nice' priority, so that it can run continuously even after you log off. No display or text will appear on the screen; all text output (STDOUT and STDERR) will go to the "resultsfile" that you name, though you can save data or images to other files using Mathematica's Display or Export or Put commands. You can check on the status of the job using the Unix command "ps". You must name your commandfile (containing the Mathematica expressesion) and the name of a (not-yet-existing) file to which text output (stdout,stderr) should be written. For example, mathbg myjob.m myjob.out
