Unix programming?

Commands don’tneedto be efficient. If your current directory is /usr/local/games/, and you were to run the command cd ./.././../local/../local/games/., what directory would youend up in? (Give the absolute file path.)

    you need to understand what the dot and double dot mean. go back and read up, as it is VITAL!

    A single . doesn't go anywhere, so those can be removed.  The path is equivalent to ../../local/../local

    Then, "going into" a directory (the first "local/") and then going back out again with ../ does nothing, so you can remove that.   Now it's equivalent to ../../local

    And since . is /usr/local/games/ to begin with, then ../../ is the same as /usr/, so the final spot you land is in /usr/local/

    The starting directory is "/usr/local/games/" 

    . <-- the current directory (/usr/local/games/) 

    /.. <-- up one directory  (/usr/local/) 

    /. <-- again, the current directory (now /usr/local/) 

    /.. <-- up one more directory (/usr) 

    /local <-- back down to local (/usr/local/) 

    /.. <-- and back up on (/usr) 

    local/games/ <-- puts you right back where you started.
