I want to print data in between two lines in a file sample.txt through more or cat command on the screen. For that I am using below sed command to give the BEGIN and END text.
Content of sample.txt
Code:
server01:~ # cat /proc/mdstat
Hello this is a text message 1
Hello this is a text message 2
Hello this is a text message 3
Hello this is a text message 4
Hello this is a text message 5
server01:~ # more sample.txt | sed -n -e '/server01:~ # cat/,$p' | sed -e '/server01:~ # df -k/,$d'
Hello this is a text message 1
Hello this is a text message 2
Hello this is a text message 3
Hello this is a text message 4
Hello this is a text message 5
The above method is working fine but since I may have more cat text for server01 in sample.txt so I want to include complete text 'server01:~ # cat /proc/mdstat' in the BEGIN or END in between the sed / / for exact matching. But it gives error when I put like below because the matching string itself contains Hash (/) :
Code:
server01:~ # more sample.txt | sed -n -e '/server01:~ # cat/proc/mdstat/,$p' | sed -e '/server01:~ # df -k/,$d'

io::async::protocol::linestream
IO::Async::Protocol::LineStream(3pm) User Contributed Perl Documentation IO::Async::Protocol::LineStream(3pm)NAME
"IO::Async::Protocol::LineStream" - stream-based protocols using lines of text
SYNOPSIS
Most likely this class will be subclassed to implement a particular network protocol.
package Net::Async::HelloWorld;
use strict;
use warnings;
use base qw( IO::Async::Protocol::LineStream );
sub on_read_line
{
my $self = shift;
my ( $line ) = @_;
if( $line =~ m/^HELLO (.*)/ ) {
my $name = $1;
$self->invoke_event( on_hello => $name );
}
}
sub send_hello
{
my $self = shift;
my ( $name ) = @_;
$self->write_line( "HELLO $name" );
}
This small example elides such details as error handling, which a real protocol implementation would be likely to contain.
DESCRIPTION EVENTS
The following events are invoked, either using subclass methods or CODE references in parameters:
on_read_line $line
Invoked when a new complete line of input is received.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
on_read_line => CODE
CODE reference for the "on_read_line" event.
METHODS
$lineprotocol->write_line( $text )
Writes a line of text to the transport stream. The text will have the end-of-line marker appended to it; $text should not end with it.
