  2. Talk Overview • What is Linux? • OS Layout • Using the Command line • Editing files • Networking with SSH • Conclude

  3. What is Linux? • History and People • Richard M. Stallman • No Free Unix • Linus Travolds • Alan Cox • Licensing • GPL • LGPL • BSD

  4. What is Linux? • Distribution Concept • Free Distributions • Fedora Core • Debian and Ubuntu • Gentoo • Slackware • Many, many more • Commercial Distributions • Red Hat Enterprise • Suse • Yellow Dog

  5. OS Layout • File System • Layout • Ownership • Processes • Ownership • Priority • Binary File types • Big Endian • Little Endian

  6. OS Layout: File ownership • Everything is a file • chown • chmod - demo • Owner, Group, Other • d rwx rwx rwx

  7. OS Layout: Processes • Every process is owned by a user • Root ownership • Daemon ownership • User ownership • ps demo

  8. OS layout: Big endian & Little endian • Otherwise known as the “NUXI” problem • Imagine 1025 stored in binary: • 00000000 00000000 00000100 00000001 Most significant value at lowest storage address (i.e., first) Big-Endian memory 00 00000000 01 00000000 02 00000100 03 00000001 Least significant value stored first Little-Endian memory 00 00000001 01 00000100 02 00000000 03 00000000

  9. Using the command line • What is a shell? • Bash • Tcsh • Zsh • Man(ual) pages • cd, ls, rm, mv, cp, ps, mkdir • pwd, who, w, gcc, g77, find, whereis

  10. Editors • vi • Vim • Emacs, xemacs • Nano • OpenOffice • Groff, tex, latex • dos2unix

  11. Networking with ssh • Network security using encryption • Ssh – make remote connections • Scp – copy remote files • Sftp – secure file transfer protocol • X11 forwarding using SSH

  12. Conclusion • Linux is a free (as in freedom) Unix-like operating system • There are many command line tools to learn • Documentation in the man pages • Many different programs to edit files • Ssh is a very useful tool for connecting to remote machines
