This could be written as :

t = popen( "lp *.ps" ).read()

or you could make a function to do that:

def pipe_read( command ) :
	return popen( command ).read()

then call it :

t = pipe_read( "lp *.ps" )

It is common for shell scripting languages to execute external
programs rather than implement things in the shell itself.  Perl has
this backtick syntax for executing an external command.
