Re: punctuation marks ?

Hello,

Depends on where you use them :-)

The typical usage is:
  "   string with variable substitutions
  '   literal string (suppress substitutions)
  `   execute the command and use the result

So: 'pwd' gives you those three characters, while `pwd` gives you the current
directory.

These work in bash and perl, and probably most of the shells.

In LaTeX, they are left and right quotes, so you should quote like `this' or
like ``this'' (" is not used at all).

One common set of names is:
  "   double quote
  '   single quote
  `   back quote
