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 ?

Email::MIME::ContentType(3pm) User Contributed Perl Documentation Email::MIME::ContentType(3pm)NAME
Email::MIME::ContentType - Parse a MIME Content-Type Header
VERSION
version 1.013
$Id: /my/pep/Email-MIME-ContentType/trunk/lib/Email/MIME/ContentType.pm 31133 2007-03-22T19:52:26.296283Z rjbs $
SYNOPSIS
use Email::MIME::ContentType;
# Content-Type: text/plain; charset="us-ascii"; format=flowed
my $ct = 'text/plain; charset="us-ascii"; format=flowed';
my $data = parse_content_type($ct);
$data = {
discrete => "text",
composite => "plain",
attributes => {
charset => "us-ascii",
format => "flowed"
}
};
FUNCTIONS
parse_content_type
This routine is exported by default.
This routine parses email content type headers according to section 5.1 of RFC 2045. It returns a hash as above, with entries for the dis-
crete type, the composite type, and a hash of attributes.
WARNINGS
This is not a valid content-type header, according to both RFC 1521 and RFC 2045:
Content-Type: type/subtype;
If a semicolon appears, a parameter must. "parse_content_type" will carp if it encounters a header of this type, but you can suppress this
by setting $Email::MIME::ContentType::STRICT_PARAMS to a false value. Please consider localizing this assignment!
