Full Discussion: Returning two lines if they both match strings
Top Forums Shell Programming and Scripting Returning two lines if they both match strings Post 302865419 by CarloM on Friday 18th of October 2013 11:35:16 AM

Code:
$ awk '{if ((lastword=="Bill") && ($1=="Jones")) {print lastline ORS $0} lastword=$1; lastline=$0}' file
Bill Blue
Jones Red

EDIT: Actually, slightly neater (and conforming more closely to your requirements):
Code:
awk '{if ((lastline ~ /^Bill/) && ($0 ~ /^Jones/)) {print lastline ORS $0} lastline=$0}' file

setmaillist

setmaillist(1)						      General Commands Manual						    setmaillist(1)

NAME

       setmaillist - create a binary mailing list

SYNOPSIS

       setmaillist bin tmp

DESCRIPTION

       setmaillist reads a mailing list from its standard input.

       setmaillist writes the mailing list in a binary format to tmp; it then moves tmp to bin.  tmp and bin must be on the same filesystem.

       If there is a problem creating tmp, setmaillist complains and leaves bin alone.

       The binary mailing list format is portable across machines.

       setmaillist always creates bin world-readable.

MAILING LIST FORMAT

       The mailing list read by setmaillist is a series of lines.  NUL bytes are not allowed.

       If a line begins with a dot or slash, setmaillist takes the entire line as an include file name.

       If  a line begins with an ampersand, setmaillist takes the rest of the line as a recipient address.  If a line begins with a letter or num-
       ber, setmaillist takes the entire line as a recipient address.  Each recipient address must include a fully qualified domain name.  Recipi-
       ent addresses longer than 800 bytes are not allowed.

       setmaillist ignores blank lines and lines beginning with #.  It also ignores spaces and tabs at the ends of lines.

       For example,

	  god@heaven.af.mil
	  djb@silverton.berkeley.edu

       is a mailing list with two addresses.
