Still having some trouble deleting firstword

First off, I want to say thank inpavan for the help. To answer inpavens question regarding what I am trying to delete, I am trying to delete two words within a file. The file is about 80 lines in length. I do not want to delete any line just the words discovery and named.

1. The sed 's/yourword//g' yourfile > newfile - To delte the words only worked to delete either word, but only one word at a time.

2. The use of sed 's/firstword.*secondword//g' filename worked only to delete the secondword, the first word was ignored.

I am trying to figure out how to delete two words at the same time.

Again thanks for the help.

SPELL(1)						      General Commands Manual							  SPELL(1)

NAME
spell, spellin, spellout - find spelling errors SYNOPSIS
spell [ option ] ... [ file ] ... /usr/src/cmd/spell/spellin [ list ] /usr/src/cmd/spell/spellout [ -d ] list DESCRIPTION
Spell collects words from the named documents, and looks them up in a spelling list. Words that neither occur among nor are derivable (by applying certain inflections, prefixes or suffixes) from words in the spelling list are printed on the standard output. If no files are named, words are collected from the standard input. Spell ignores most troff, tbl and eqn(1) constructions. Under the -v option, all words not literally in the spelling list are printed, and plausible derivations from spelling list words are indi- cated. Under the -b option, British spelling is checked. Besides preferring centre, colour, speciality, travelled, etc., this option insists upon -ise in words like standardise, Fowler and the OED to the contrary notwithstanding. Under the -x option, every plausible stem is printed with `=' for each word. The spelling list is based on many sources, and while more haphazard than an ordinary dictionary, is also more effective in respect to proper names and popular technical words. Coverage of the specialized vocabularies of biology, medicine and chemistry is light. Pertinent auxiliary files may be specified by name arguments, indicated below with their default settings. Copies of all output are accu- mulated in the history file. The stop list filters out misspellings (e.g. thier=thy-y+ier) that would otherwise pass. Two routines help maintain the hash lists used by spell. Both expect a list of words, one per line, from the standard input. Spellin adds the words on the standard input to the preexisting list and places a new list on the standard output. If no list is specified, the new list is created from scratch. Spellout looks up each word in the standard input and prints on the standard output those that are missing from (or present on, with option -d) the hash list. FILES
D=/usr/dict/hlist[ab]: hashed spelling lists, American & British S=/usr/dict/hstop: hashed stop list H=/usr/dict/spellhist: history file /usr/lib/spell deroff(1), sort(1), tee(1), sed(1) BUGS
The spelling list's coverage is uneven; new installations will probably wish to monitor the output for several months to gather local addi- tions. British spelling was done by an American. SPELL(1)
