Grep specific records from a file of records that are separated by an empty line
Hi everyone.
I am a newbie to Linux stuff. I have this kind of problem which couldn't solve alone. I have a text file with records separated by empty lines like this:
I want to grep records that have both 'Email' and 'Age' like in the last one and put that record in another file. How to do that?
Thanks in advance

Reason: Added code tags.
I have a file which is 5 million records. And each records has 412 fields has delimited by "|". So that makes each records to be 2923 bytes long. I wanted to extract specific records like top 100 or 2500 - 5000, 50001 - 10000 etc. from this file.
I tried using head command for top 100 records,... (1 Reply)
I am trying to cut the first 10 characters from a file only if the file has 'xyz' in field 185-188.
I tried this
cat filename | cut -c1-10
but this gives me all the records regardless of what is in field 185-188.
Is this doable ?
Thanks in advance for responses. (2 Replies)

email::sender
Email::Sender(3pm) User Contributed Perl Documentation Email::Sender(3pm)NAME
Email::Sender - a library for sending email
VERSION
version 0.110005
SYNOPSIS
my $message = Email::MIME->create( ... );
# produce an Email::Abstract compatible message object,
# e.g. produced by Email::Simple, Email::MIME, Email::Stuff
use Email::Sender::Simple qw(sendmail);
use Email::Sender::Transport::SMTP qw();
use Try::Tiny;
try {
sendmail(
$message,
{
from => $SMTP_ENVELOPE_FROM_ADDRESS,
transport => Email::Sender::Transport::SMTP->new({
host => $SMTP_HOSTNAME,
port => $SMTP_PORT,
})
}
);
} catch {
warn "sending failed: $_";
};
OVERVIEW
Email::Sender replaces the old and sometimes problematic Email::Send library, which did a decent job at handling very simple email sending
tasks, but was not suitable for serious use, for a variety of reasons.
Most users will be able to use Email::Sender::Simple to send mail. Users with more specific needs should look at the available
Email::Sender::Transport classes.
Documentation may be found in Email::Sender::Manual, and new users should start with Email::Sender::Manual::QuickStart.
IMPLEMENTING
Email::Sender itelf is a Moose role. Any class that implements Email::Sender is required to provide a method called "send". This method
should accept any input that can be understood by Email::Abstract, followed by a hashref containing "to" and "from" arguments to be used as
the envelope. The method should return an Email::Sender::Success object on success or throw an Email::Sender::Failure on failure.
