Linux & Applications Sean GavinWayne State University multi-user environment -- log in: user name and password -- you never turn the computer on or off

Linux Linux with KDE graphic user interface navigation – where are my files? command line interface – listing, moving, finding, copying … my files applications – web browsing, text viewing, editing … my files

graphic user interface KDE GNOME makes the desktop look like a windows desktop – point and click

home – directory browser search for files help shell – terminal for entering text commands start menu – like windows icons

Command Line Interface Shell Icon – window with a “prompt” rhic15:sean> ls type keyword commands – execute programs command “ls” lists files in a directory file names have format name.xxx (no blank spaces!!) xxx – extension indicates the files function sean.tex< word processor (latex) sean.cpp, sean.f< C++ or Fortran program momLetter.txt< plain text (asci) web_page.htm< web document (html) no blank spaces, case sensitive

Favorite Unix Commands ls list files> ls > ls *.txt(list files with extension.txt) ls –l list files with size, etc.> ls –l *.cpp ls –a list all files > ls –a lpr prints files> lpr sean.txt (default printer) > lpr –Pmono1200 sean.txt (specify printer) cd change directory > cd MyDirectory > cd (  home directory) mkdir make new directory> mkdir MyNobel rm remove file> rm wrongStuff.txt rmdir remove directory> rm WrongStuff (delete contents first) cp copy file> cp old.txt new.txt (keeps old.txt) mv move file> mv old.txt new.txt (kills old.txt) more types file on screen> more money.txt pwd print working directory> pwd

FTP – Moving Files

Running Programs from Command Line can type program name at the prompt to start application: > netscape &web browser > ghostview pic.ps &postscript file viewer > gv pic2.eps &a better postscript viewer > acroread taxReturn.pdf &acrobat pdf file viewer compile and execute programs that you have written text editors: emacs, xemacs note: also find common programs are on the start menu

Summary Unix – many choices, infinite possibilities The setup at BNL, Cornell, Fermi will be different navigation in KDE graphic user interface command line interface – ls, cd, mv, cp, rm applications – netscape, ghost view, xemacs
