I do have to send a report regarding pasting some clipboard content into a web rich editor and I need a way to dump/restore the clipboard content to (probably) HTML.
I realise you've already found this, but for the benefit of people who turn up here from Google, the solution given for RTF data at Getting RTF data out of Mac OS X pasteboard (clipboard) works fine for getting HTML out of the clipboard, too.
That is, the command
osascript -e 'the clipboard as «class HTML»' | perl -ne 'print chr foreach unpack("C*",pack("H*",substr($_,11,-3)))'
