Full Discussion: Grep with multiple instances of same pattern
Top Forums Shell Programming and Scripting Grep with multiple instances of same pattern Post 302348977 by daPeach on Sunday 30th of August 2009 03:48:56 PM

I don't believe grep is intended to do such a thing, but something like this
Code:
perl -pe 's/.*(Location.*?Received).*/$1/' your_file

can.

edit:
Well i was wrong: grep could, though
man grep says -P --perl-regexp
Interpret PATTERN as a Perl regular expression. This is highly experimental and grep -P may warn of unimplemented features

and in deed, Debian GNU/Linux says:
grep: Support for the -P option is not compiled into this --disable-perl-regexp binary

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
