perhaps, but I'd do it with sed, since I like sed.
give this a try
history | sed 's/^ *[^ ]* *//' | sort -u > sortedhistory.txt
The sed line says match any number of spaces " *" followed by
any number of non-spaces "[^ ]*" followed by any number of spaces " *" again
and replaces them with nothing "//". Which just gets rid of the numbering.
then sort -u will take care of uniqueness for you.
have fun,
greg
