UNIX software at Nevis can be generally grouped into these categories:

UNIX system commands

These are programs that are part of almost any UNIX system installation. To get information about a UNIX command, use man For example, to get information about the grep command, type man grep.

If you want to learn about the UNIX operating system and its commands, look in UNIXhelp. For a popular beginner's introduction to UNIX, see UNIX is a Four-Letter Word.

Utilities

The GNU Consortium is the standard source for free UNIX utility software, including the utilities available in Linux. An important GNU utility is the emacs editor. To get information about most GNU utilities, you can use the info facility which is easily available from within emacs.

The steps involved to see the GNU documentation are:

• type emacs to invoke the editor
• (if this is your first time using emacs) learn the basic navigation commands by typing C-h t <-- this means to hold down the "Ctrl" key, type "h", let go of the "Ctrl" key, and type "t".
• invoke info by typing C-h i.

Physics and research-related software

These programs are not necessarily part of a standard Linux installation, including Geant4, ROOT, CLHEP, PAW, OpenOffice, gv, gsview, and latex. There are also a set of compiler tools available, which are useful for large projects or for using our condor batch farm. The setup command is required to use some of the programs.

Electronic Mail

E-mail is such an important tool for a research scientist that it has been given a section all its own.
