Hi Dwight,

I was fiddling with the script that you sent, this seems to work OK
will all the sed versions that I've tried:

1,/<.BLOCKQUOTE>/{
  /<.BLOCKQUOTE>/s//<font face="verdana" size="2">When installation
completes,
click <a href=..\\..\\Update.asp>here <\/a>to
return.<\/font><\/BLOCKQUOTE>/
}

NB the second line of the script will wrap in posting.

The 1,/<.BLOCKQUOTE>/ { ... } ensures that only the first occurrence
of <.BLOCKQUOTE> is changed, which is (I think) what you were trying
to achieve.

In fact, as sed in Cygwin is GNU sed you can also use 0,/RE/ as the
address range (other seds don't usually support this).  This format
is very useful if the /RE/ can appear in the first line, in which
case 1,/RE/ won't find it, because sed doesn't attempt to match the
second part of an address range against the current line and will
only attempt to match it against the next line.
