  1. Linux & ApplicationsSean Gavin Wayne State University • multi-user environment-- log in: user name and password -- you never turn the computer on or off

  2. 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

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

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

  5. 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

  6. 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

  7. FTP – Moving Files
