Subject: $stdin

Hello,

first excuse me my bad english.

i have write a little send_mail script. now i pipe the messagetext from
another program, like cat /var/mailtext| send-mail.rb

the program source:

smtp_message = ""
  
 temp = $stdin
  
 temp.each do |f|
    smtp_message += f
 end

this is runing very well, but when no text is in the pipe, the program
is waiting for input.

my question is, how can i ask, if text in $stdin, without the program is
waitung for input.

ciao

Stefan
