We can plot this using the command: plot "results" w l The command plot "results" only plots stars, no line. The command help is also useful. For 3D plots, i.e. a table with three columns, we use the command splot. 10.5 Unix and Linux Unix (and Linux) are not used as often as Windows platforms, although for scientific programming they are popular development platforms. The Unix operating system is a command line system with several graphical interfaces. Especially in Linux, the graphical interfaces are well developed so that you get a windows like look and feel. Although you can easily browse through the directories, create new directories and move data around with a few mouse clicks, it may be interesting to know at least a few Unix commands: • ps: list of my processes, • kill -9 id : kill the process with id id,
10.5. UNIX AND LINUX 241 • top: list all processes and resource use, • mkdir: make a new directory, • rmdir: remove an (empty) directory, • pwd: name of the current directory, • cd dir: change directory to dir, • ls: list the files in the current directory • cp from to: copy the file from to the file or directory to. if the file to exists, it is overwritten, unless you use cp -i from to, • mv from to: move the file from to the file or directory to. If the file to exists, it is overwritten, unless you use mv -i from to, • rm files: remove all the files in the list files. rm * removes everything (be careful) chmod mode files : change the user mode for files. See http://www.physics.wm.edu/unix_intro/outline.html for on-line help.
