Grep two lines at a time
Hello;

i have a log file which had Invalid, error, missing words in it.
I want to grab a line which matches either of the above words and one more line below the grepped line.

Can this be done?
I looked on other places on your forum, but there is nothing which is working.
I tried following things:

sed -n '/Invalid/ {p; n; p;}' r0035251.rpt <--- But this one does not have a case sensitive as well as multiple pattern matching.

nawk is not available on my system

grep -B <---- again not available.

egrep -i command gives me the matched line, but I am not sure how to combine it with sed to be able to display the next line too!

Can anyone help?

Thanks
Josh
thanks

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.
