Scripts, Of Various Kinds
These scripts are not specific to any particular platform, though they will generally require some combination of open source tools such as ksh, perl and others.
Any file that does not have an extension is presumed to be a Korn Shell (ksh) script. Compatability with Bourne Shell (sh) or Borne Again Shell (bash), while not having been tested, is probably not illusive.
If you're unlucky enough to be under Windows, you can get ksh as part of the UWIN Toolkit from AT&T Research, which I recommend for doing anything command-line oriented under Windows.
General UNIX command line familiarity is recommended.
