       while list-1; do list-2; done
       until list-1; do list-2; done
              The while command continuously executes the list list-2 as  long
              as the last command in the list list-1 returns an exit status of
              zero.  The until command is  identical  to  the  while  command,
              except  that  the test is negated; list-2 is executed as long as
              the last command in list-1 returns a non-zero exit status.   The
              exit  status  of the while and until commands is the exit status
              of the last command executed in list-2, or zero if none was exe‐
              cuted.

本想裝Ubuntu 15.4,但我後來先試Linux Mint 17.1,只因好奇它為何是下載排第一,
裝完之後發現運行還比Win7快,而且它裝完就有LibreOffice,
而且最重要的是,它也直接裝了解碼器,片片是直接點了就播...

外老是教用PlayOnLinux+Office2010,我是還沒試,
網路上有教學,這應該是最簡單的方法了...
