russo@dragon:~>bash --version
GNU bash, version 2.05.0(1)-release (sparc-sun-solaris2.7)
Copyright 2000 Free Software Foundation, Inc.
russo@dragon:~>uname -a
SunOS dragon 5.7 Generic_106541-07 sun4u sparc SUNW,Ultra-Enterprise
russo@dragon:~>PS1='PS1$ '
PS1$ PS2=''
PS1$ echo 'abc                             <----------------here I hit return
PS1$ def'
abc
def
PS1$
