SDF-Specific Commands
The following is a list of commands created for use on the SDF Public Access UNIX System. Virtually all of them were written by the sysadmin, smj, and their uses are almost all SDF-centric. Very few have manpages, with most only being mentioned in obscure corners of the online documentation; hence, the descriptions for some of these commands may be inaccurate, and I may also have left some out. If you find any errors or omissions here, please correct me.
This information is now also available in the SDF tutorials, where it can be edited by any MetaARPA member.
