SCTB: Appendix

Version 0.80

The programs described below are not part of the sctb distribution. Some were developed at NRL, and some were developed externally. Programs developed at NRL are distributed without charge and without support, subject to the usual disclaimer. For policies regarding distribution of other software please see the accompanying links.

Programs developed outside NRL:

• Perl is, officially, "a language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information." In practice, it provides a platform independent combination of C, awk, and sed, retaining a shell script's access to the command line and underlying OS commands. Perl is available for almost all computers and operating systems.
  
  
• Shell programming (either csh, tcsh, sh, bash, ksh, or your favorite) is a good way to make quick and dirty output processing scripts as in the examples. Using fgrep, sed, awk, head, tail, and bc, amazing things can be achieved. They can almost always be achieved more easily in perl.
  
  
• gnuplot is a ``command-line driven interactive function plotting utility'' which runs on just about every platform. The 3.7 version includes a set of routines which allow you to fit data to more or less arbitrary analytical functions.
