I'm just looking for really good unix book on programming in all shells, and system adminstrator books, and well as just all around really good books on unix.
I know the "Unix Shell Programming" book that Neo recommends I recently purchased that it is very good.
But when I heard that Neo has around 30 books on unix I wanted to hear more about them. So if you post teh books you would recommend and not just Neo everyone's choices - and maybe even not recommeded just in case!
Thank yout

dbix::class::helper::resultset::correlaterelationship
DBIx::Class::Helper::ResultSet::CorrelateRelationship(3pUser Contributed Perl DocumentatDBIx::Class::Helper::ResultSet::CorrelateRelationship(3pm)
NAME
DBIx::Class::Helper::ResultSet::CorrelateRelationship - Easily correlate your ResultSets
VERSION
version 2.013002
SYNOPSIS
package MyApp::Schema::ResultSet::Author;
use base 'DBIx::Class::ResultSet';
__PACKAGE__->load_components(qw(Helper::ResultSet::CorrelateRelationship));
sub with_book_count {
my $self = shift;
$self->search(undef, {
'+columns' => {
book_count => $self->correlate('book')->count_rs->as_query
}
});
}
1;
And then elsewhere, like in a controller:
my $rows = $schema->resultset('Author')->with_book_count->all;
DESCRIPTION
Correlated queries are one of the coolest things I've learned about for SQL since my initial learning of SQL. Unfortunately they are
somewhat confusing. DBIx::Class has supported doing them for a long time, but generally people don't think of them because they are so
rare. I won't go through all the details of how they work and cool things you can do with them, but here are a couple high level things
you can use them for to save you time or effort.
If you want to select a list of authors and counts of books for each author, you could use "group_by" and something like "COUNT(book.id)",
but then you'd need to make your select list match your "group_by" and it would just be a hassle forever after that. The "SYNOPSIS" is a
perfect example of how to implement this.
If you want to select a list of authors and two separate kinds of counts of books for each author, as far as I know, you must use a
correlated subquery in DBIx::Class. Here is an example of how you might do that:
package MyApp::Schema::ResultSet::Author;
use base 'DBIx::Class::ResultSet';
__PACKAGE__->load_components(qw(Helper::ResultSet::CorrelateRelationship));
sub with_good_book_count {
my $self = shift;
$self->search(undef, {
'+columns' => {
good_book_count => $self->correlate('books')->good->count_rs->as_query
}
});
}
sub with_bad_book_count {
my $self = shift;
$self->search(undef, {
'+columns' => {
bad_book_count => $self->correlate('books')->bad->count_rs->as_query
}
});
}
1;
And then elsewhere, like in a controller:
my $rows = $schema->resultset('Author')
->with_bad_book_count
->with_good_book_count
->all;
This assumes that the Book resultset has "good" and "bad" methods.
See "NOTE" in DBIx::Class::Helper::ResultSet for a nice way to apply it to your entire schema.
METHODS
correlate
$rs->correlate($relationship_name)
Correlate takes a single argument, a relationship for the invocant, and returns a resultset that can be used in the selector list.
