Hi,
I know how to use awk to search some expressions like five consecutive numbers, , this is easy.
However, how do I make awk print the pattern that is been matched?
For example:
input: usa,canada99292,japan222,france59664,egypt223
output:99292,59664 (6 Replies)

Hi, I have 2 files that I have modified to basically match each other, however I want to determine what (if any) line in file 1 does not exist in file 2. I need to match column $1 and $2 as a single string in file1 to $1 and $2 in file2 as these two columns create a match.

tap::parser::multiplexer
TAP::Parser::Multiplexer(3) User Contributed Perl Documentation TAP::Parser::Multiplexer(3)NAME
TAP::Parser::Multiplexer - Multiplex multiple TAP::Parsers
VERSION
Version 3.28
SYNOPSIS
use TAP::Parser::Multiplexer;
my $mux = TAP::Parser::Multiplexer->new;
$mux->add( $parser1, $stash1 );
$mux->add( $parser2, $stash2 );
while ( my ( $parser, $stash, $result ) = $mux->next ) {
# do stuff
}
DESCRIPTION
"TAP::Parser::Multiplexer" gathers input from multiple TAP::Parsers. Internally it calls select on the input file handles for those
parsers to wait for one or more of them to have input available.
See TAP::Harness for an example of its use.
METHODS
Class Methods
"new"
my $mux = TAP::Parser::Multiplexer->new;
Returns a new "TAP::Parser::Multiplexer" object.
Instance Methods
"add"
$mux->add( $parser, $stash );
Add a TAP::Parser to the multiplexer. $stash is an optional opaque reference that will be returned from "next" along with the parser and
the next result.
"parsers"
my $count = $mux->parsers;
Returns the number of parsers. Parsers are removed from the multiplexer when their input is exhausted.
"next"
Return a result from the next available parser. Returns a list containing the parser from which the result came, the stash that corresponds
with that parser and the result.
my ( $parser, $stash, $result ) = $mux->next;
If $result is undefined the corresponding parser has reached the end of its input (and will automatically be removed from the multiplexer).
When all parsers are exhausted an empty list will be returned.
if ( my ( $parser, $stash, $result ) = $mux->next ) {
if ( ! defined $result ) {
# End of this parser
}
else {
# Process result
}
}
else {
# All parsers finished
}
