[CentOS] Retriving attachment from eml files

Hello,
 
I have over 2000 emails (eml files) each one of them have attached html.
I need to get one line of that attachment and I need to process that as
a text.
 
Does anyone know which command will show me attachment of eml file as
output and decode that ?
 
Thanks in advance,
 Paul
