But if that loop ever stops running, the 'file' will block.
Ah, effectively a "replinishing" pipe. That would work. The downside, as you mentioned, is that it must be supported by a running process.
It would be nice to have a native file type (again, like an SQL view) that contains "instructions" to materialize data, but only materializes such data when it is read.
I am trying to add a permanent route on my server, but whenever i reboot it dissapears.
Please does anyone know the correct command to use.
route add XXX.XXX.XXX.XXX DDD.DDD.DDD.DDD
the above is what i have done.

On AIX 5.2 as root, installed Seamonkey and have to type

To set up a permanent alias, I did the following

alias seamk='/seakey/seamonkey/seamonkey'
and saved it to /home/alias_file

Hi guys,
I'm running Solars 8 on a V100 server at home for testing.
If I switch user to root and do:
# echo $PATH
This is the output:
/usr/sbin:/usr/bin
I'm using rsync over ssh and need to add /usr/local/bin and /user/local/sbin.
I do this by running the line:

I set my TERM variable to work with SMIT and everything works fine but when I logged out and log in again I have to set the variable again.
How can I set a permanent variable into the system so it will be as I wish even if a reboot is needed?
I set variables this way:

I try to understand the meaning of an inode. I wonder whether

dbix::class::resultsource::view
DBIx::Class::ResultSource::View(3) User Contributed Perl Documentation DBIx::Class::ResultSource::View(3)NAME
DBIx::Class::ResultSource::View - ResultSource object representing a view
SYNOPSIS
package MyApp::Schema::Result::Year2000CDs;
use base qw/DBIx::Class::Core/;
__PACKAGE__->table_class('DBIx::Class::ResultSource::View');
__PACKAGE__->table('year2000cds');
__PACKAGE__->result_source_instance->is_virtual(1);
__PACKAGE__->result_source_instance->view_definition(
"SELECT cdid, artist, title FROM cd WHERE year ='2000'"
);
__PACKAGE__->add_columns(
'cdid' => {
data_type => 'integer',
is_auto_increment => 1,
},
'artist' => {
data_type => 'integer',
},
'title' => {
data_type => 'varchar',
size => 100,
},
);
DESCRIPTION
View object that inherits from DBIx::Class::ResultSource
This class extends ResultSource to add basic view support.
A view has a "view_definition", which contains a SQL query. The query can only have parameters if "is_virtual" is set to true. It may
contain JOINs, sub selects and any other SQL your database supports.
View definition SQL is deployed to your database on "deploy" in DBIx::Class::Schema unless you set "is_virtual" to true.
Deploying the view does not translate it between different database syntaxes, so be careful what you write in your view SQL.
Virtual views ("is_virtual" true), are assumed to not exist in your database as a real view. The "view_definition" in this case replaces
the view name in a FROM clause in a subselect.
EXAMPLES
Having created the MyApp::Schema::Year2000CDs schema as shown in the SYNOPSIS above, you can then:
$2000_cds = $schema->resultset('Year2000CDs')
->search()
->all();
$count = $schema->resultset('Year2000CDs')
->search()
->count();
If you modified the schema to include a placeholder
__PACKAGE__->result_source_instance->view_definition(
"SELECT cdid, artist, title FROM cd WHERE year = ?"
);
and ensuring you have is_virtual set to true:
__PACKAGE__->result_source_instance->is_virtual(1);
You could now say:
$2001_cds = $schema->resultset('Year2000CDs')
->search({}, { bind => [2001] })
->all();
$count = $schema->resultset('Year2000CDs')
->search({}, { bind => [2001] })
->count();
SQL EXAMPLES
is_virtual set to false
$schema->resultset('Year2000CDs')->all();
SELECT cdid, artist, title FROM year2000cds me
is_virtual set to true
$schema->resultset('Year2000CDs')->all();
SELECT cdid, artist, title FROM
(SELECT cdid, artist, title FROM cd WHERE year ='2000') me
METHODS
is_virtual
__PACKAGE__->result_source_instance->is_virtual(1);
Set to true for a virtual view, false or unset for a real database-based view.
view_definition
__PACKAGE__->result_source_instance->view_definition(
"SELECT cdid, artist, title FROM cd WHERE year ='2000'"
);
An SQL query for your view. Will not be translated across database syntaxes.
deploy_depends_on
__PACKAGE__->result_source_instance->deploy_depends_on(
["MyApp::Schema::Result::Year","MyApp::Schema::Result::CD"]
);
Specify the views (and only the views) that this view depends on. Pass this an array reference of fully qualified result classes.
OVERRIDDEN METHODS
from
Returns the FROM entry for the table (i.e. the view name) or the SQL as a subselect if this is a virtual view.
OTHER METHODS
new
The constructor.
