2.5.2 The Pipe command

   As you can see, this is a somewhat difficult way of using pipes,
needing a lot of typing especially compared to the UNIX pipes. There is
a solution for that.
   Andy Finkel, a former Commodore software engineer wrote a command
called `Pipe' (not to be confused with `PIPE:') that simplifies the use
of the `PIPE:' device. Unfortunately, this command did not make it into
the 2.04 release. However, Commodore has given the permission to
distribute this, and a few other commands, freely. (Sources: Fish disk
673, Aminet, `util/cli/finkelshelltools.lha')
   For some reason Commodore did not include these commands in the later
OS releases, although they work fine even with OS 3.1 (V40). Thus all
users are required to get them from the above sources if they wish to
use them.
   The Pipe command usage is simple. The commands to be run with their
inputs and outputs piped together are given as arguments to the
command, separated by the | (vertical bar) character:
         1> Pipe List SYS: | More
             or
         1> Pipe List: SYS: NOHEAD | Sort IN: OUT: | More
Notice how Sort needs `IN:' and `OUT:'. These devices don't actually
exist, but the Pipe command simulates them with the PIPE:. This is
necessary because C:Sort can not use the `standard IO', but insists on
files.
   The separator character | can be configured to be something else
with the local variable __PCHAR.
