egrep --color=always 'zsh\.'

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

        % apt-file search zsh. | egrep
      --color=always 'zsh\.'
      
      ... if using egrep, the above makes sure that the dot is taken
      literally.  I have a function that ends up trying to create the
      above:
      
          % func 'zsh\.'
      
      ... which will attempt:
      
        apt-file search "$1" | egrep
      --color=always $1
    
    ... and it works fine unless I want to
      force a literal char, as above.  zsh is removing the quotes as she
      properly does, but in this case I need to preserve them since
      egrep needs them.  I know I've done this before.  Something in the
      (Q) continuum?  It has to be egrep since I normally want the regex
      interpretation, it's just this odd case where I need a regex char
      forced literal.   I know it's doable.
