Command arguments
=================

   Eshell recognizes several different kinds of command arguments:

  1. Strings (also called textual arguments)

  2. Numbers (floating point or integer)

  3. Lisp lists

  4. Lisp symbols

  5. Emacs buffers

  6. Emacs process handles

   Most users need to worry only about the first two.  The third, Lisp
lists, occur very frequently, but almost always behind the scenes.

   Strings are the most common type of argument, and consist of nearly
any character.  Special characters--those used by Eshell
specifically--must be preceded by a backslash (`\').  When in doubt, it
is safe to add backslashes anywhere and everywhere.

   Here is a more complicated `echo' example:

     echo A\ Multi-word\ Argument\ With\ A\ \$\ dollar

   Beyond this, things get a bit more complicated.  While not beyond the
reach of someone wishing to learn, it is definitely beyond the scope of
this manual to present it all in a simplistic manner.  Get comfortable
with Eshell as a basic command invocation tool, and learn more about the
commands on your system; then come back when it all sits more familiarly
on your mind.  Have fun!
