Command Line Arguements

As of version 3.01, SNOMAN has a command line arguments. Currently the following are permitted in any combination and order:-

• -c command_file: Take input fom the supplied command file rather than standard input.

• -l log_file: Define the name of the logfile. WARNING: IF A FILE OF THAT NAME ALREADY EXISTS, IT WILL BE OVERWRITTEN. (But once you see what it was intended for, we hope you will agree that this is a Good Thing.)

  This feature allows you to have meaningful logfile names.

  For instance (in UNIX):

  snoman.exe supernova.log < supernova.cmd

  Even better, this allows you to have a set of SNOMAN runs that load specific command files and produce associated logfiles with comprehensible names. For instance, you might have an executable shell script that simply executes your favorite SNOMAN runs.

  In UNIX:

  snoman.exe electrons.log < electrons.cmd
  snoman.exe positrons.log < positrons.cmd
  snoman.exe neutrons.log < neutrons.cmd
  ...

  Note: this feature was the first command line argument to be introduced and was done so without a preceeding -l (since there was no other option). For backward compatibility, this is still permitted, i.e. the -l is optional.

In VMS the -c option is not support and you cannot:-

run snoman.exe -l my_file.log

Instead you have first to define a symbol like this:-

run_snoman = "$U1:[WEST.SNOMAN.3_01.CODE]snoman.exe"

and now you can:-

run_snoman -l my_file.log
