Basic LINUX/UNIX Commands

• startx (start X-windows)
    
• exit (to exit completely once you have exit the windows
    system)
    
• ls (lists the files of the current directory or other
    directories)
    
• cd (change directory to home directory)
    e.g. If your home directory is /u/ugrad/mikep and you execute
    the command cd from another directory
    in the system, you'll be returned to /u/ugrad/mikep
    
• cd directory-name (change directory to directory-name)
    
• mkdir directory-name (creates an new directory with
    name directory-name)
    e.g. mkdir work (create directory with name work)
          cd work (change directory to work)
    
• mv file1 file2 (move file1 to file2,
    same as rename)
    e.g. mv file1 cs111 (move file1 to subdirectory cs111)
    
• rm file1 (remove file1, [color="#ff00ff"]be careful:
    once removed, is removed)
    
• rm -i file1 (remove file, but it will ask for confirmation)
    
• whois gives information about a domain.
    e.g. whois gate.net
    
• whoami (display username)
    
• whereis command-name (returns the path of command-name)
    
• man command-name (prints how command-name works)
    
• hostname (prints the hostname)
    
• cp file1 file2 (copies file1 to file2)
    
• pwd (prints the working directory, i.e. "where
    we are")
    
• pico prog1.c (use the pico text editor to modify
    prog1.c; emacs, and vi can be used also)
    
• gcc prog1.c (compile prog1.c, the executable
    is a.out), cc instead of gcc should also work.
    
• gcc -o prog1 prog1.c (same as above but the name of
    the executable is prog1)
    
• ./prog1 (run prog1; it should be used when
    just the name of the executable is not enough)
