DOUBLE QUOTES

  • To group several strings together as one argument it is necessary to use double quotes: "

  • For example:
    $ v=Hello World
    $ echo $v
      Hello
    $ v="Hello World"
    $ echo $v
      Hello World

  • NB: Variable substitutions are done inside double quotes but wildmasks are not expanded:
      e.g.   echo "*"   just prints a *
      but   echo "$v"   is the same as   echo $v
