watch - execute a program periodically [ˌpɪriˈɑːdɪkli] , showing output fullscreen
  wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add -
  #不下载 ,

-O  file  ,not number 0
      --output-document=file
          The documents will not be written to the appropriate files, but all will be concatenated together and written to file.
          If - is used as file, documents will be printed to standard output, disabling link conversion. (Use ./- to print to a
          file literally named -.)


          Use of -O is not intended to mean simply "use the name file instead of the one in the URL;" rather, it is analogous to
          shell redirection: wget -O file http://foo is intended to work like wget -O - http://foo > file; file will be truncated
          immediately, and all downloaded content will be written there.
