Grep with multiple instances of same pattern

Hi,

This is my text file I'm trying to Grep.

Apple Location Greenland Rdsds dsds fdfd ddsads http Received Return Immediately Received End

My Grep command:

grep only--matching 'Location.*Received'
e.

Because the keyword Received appears twice, the Grep command will stop at the last one:
Location Greenland Rdsds dsds fdfd ddsads http Received Return Immediately Received

I want it to stop after the first one:
Location Greenland Rdsds dsds fdfd ddsads http Received


How is that possible?

Thanks

POE::Filter::Grep(3pm)					User Contributed Perl Documentation				    POE::Filter::Grep(3pm)

NAME
POE::Filter::Grep - select or remove items based on simple rules SYNOPSIS
#!perl use POE qw( Wheel::FollowTail Filter::Line Filter::Grep Filter::Stackable ); POE::Session->create( inline_states => { _start => sub { my $parse_input_as_lines = POE::Filter::Line->new(); my $select_sudo_log_lines = POE::Filter::Grep->new( Put => sub { 1 }, Get => sub { my $input = shift; return $input =~ /sudo[d+]/i; }, ); my $filter_stack = POE::Filter::Stackable->new( Filters => [ $parse_input_as_lines, # first on get, last on put $select_sudo_log_lines, # first on put, last on get ] ); $_[HEAP]{tailor} = POE::Wheel::FollowTail->new( Filename => "/var/log/system.log", InputEvent => "got_log_line", Filter => $filter_stack, ); }, got_log_line => sub { print "Log: $_[ARG0] "; } } ); POE::Kernel->run(); exit; DESCRIPTION
POE::Filter::Grep selects or removes items based on simple tests. It may be used to filter input, output, or both. This filter is named and modeled after Perl's built-in grep() function. POE::Filter::Grep is designed to be combined with other filters through POE::Filter::Stackable. In the "SYNOPSIS" example, a filter stack is created to parse logs as lines and remove all entries that don't pertain to a sudo process. (Or if your glass is half full, the stack only selects entries that DO mention sudo.) PUBLIC FILTER METHODS
In addition to the usual POE::Filter methods, POE::Filter::Grep also supports the following. new new() constructs a new POE::Filter::Grep object. It must either be called with a single Code parameter, or both a Put and a Get parameter. The values for Code, Put, and Get are code references that, when invoked, return true to select an item or false to reject it. A Code function will be used for both input and output, while Get and Put functions allow input and output to be filtered in different ways. The item in question will be passed as the function's sole parameter. sub reject_bidoofs { my $pokemon = shift; return 1 if $pokemon ne "bidoof"; return; } my $gotta_catch_nearly_all = POE::Filter::Grep->new( Code => &reject_bidoofs, ); Enforce read-only behavior: my $read_only = POE::Filter::Grep->new( Get => sub { 1 }, Put => sub { 0 }, ); modify modify() changes a POE::Filter::Grep object's behavior at run-time. It accepts the same parameters as new(), and it replaces the existing tests with new ones. # Don't give away our Dialgas. $gotta_catch_nearly_all->modify( Get => sub { 1 }, Put => sub { return shift() ne "dialga" }, ); SEE ALSO
