Returning two lines if they both match strings
Hi

I have a problem where I have a large amount of files that I need to scan and return a line and its following line, but only when the following line begins with a string.

String one - line one must begin with 'Bill'
String two - line two must begin with 'Jones'.

If these two criteria are matched, it returns the two lines. Repeat for the whole file.

ie. original file:

Code:
Edith Blue
Edith Green
Edith Red
Bill Blue
Jones Red
Edith Green
Bill Green
Edith Red
Jones Green
Bill Blue


I'd want it to return only:

Code:
Bill Blue
Jones Red

Any ideas? No idea where to begin with this, I only have basic scripting skills with sed/awk etc... At the moment I am using this to get the filename and its following line, but it is giving me too much useless information that I have to strip off with other sed commands.

Code:
grep -A 1 "^Bill" * > test.txt

I guess there's a far more elegant way of getting only the lines I need. Any help would be lovely!

elvfmt

ELVFMT(1)							   User commands							 ELVFMT(1)

NAME

       elvfmt - adjust line-length for paragraphs of text

SYNOPSIS

       elvfmt [-w width | -width] [-s] [-c] [-i chars] [-C] [-M] [file]...

VERSION

       This page describes the Elvis 2.2_0 version of elvfmt.  See elvis(1).

DESCRIPTION

       elvfmt  is  a  simple  text formatter.  It inserts or deletes newlines, as necessary, to make all lines in a paragraph be approximately the
       same width.  It preserves indentation and word spacing.

       If you don't name any files on the command line, then elvfmt will read from stdin.

       It is typically used from within vi(1) or elvis(1) to adjust the line breaks in a single paragraph.  To do this, move the cursor to the top
       of the paragraph, type "!}elvfmt", and hit <Return>.

OPTIONS

       -w width or -width
	      Use a line width of width characters instead of the default of 72 characters.

       -s     Don't join lines shorter than the line width to fill paragraphs.

       -c     Try to be smarter about crown margins.  Specifically, this tells elvfmt to expect the first line of each paragraph to have a differ-
	      ent indentation than subsequent lines.  If text from the first input line is wrapped onto the second output line, then  elvfmt  will
	      scan ahead to figure out what indentation it should use for the second output line, instead of reusing the first line's indentation.

       -i chars
	      Allow  the indentation text to include any character from chars, in addition to spaces and tabs.	You should quote the chars list to
	      protect it from the shell.

       -C and -M
	      These are shortcuts for combinations of other flags.   is short for  and is useful for reformatting C/C++ comments.   is short for
	      and is useful for reformatting email messages.
