While I would agree with the above, Unix shells make a distinction =20
between different types of quote characters, and if you are talking =20
about command-line programming or scripts, there is an advantage to =20
quoting things in a fashion that the shell will be happy with.

Double-quotes (") permit variable, history, and alias expansion of the =20=

quoted terms, whereas single forward quotes (') give you a string =20
literal and disable expansion.  Backquotes (`) are used to perform =20
command substitution and are a synonym for "$(command)" syntax; =20
something like "echo `ls`" would be a simple example.
