FYI if you want the output of that command to be put at the end of the file use a forward tick `` in place of the double quotes "".

Is there any way to append a newline character at the end of a file(coma-separated file), through shell script?

dbd::gofer::transport::corostream5.18
DBD::Gofer::Transport::corostream(3) User Contributed Perl Documentation DBD::Gofer::Transport::corostream(3)
NAME
DBD::Gofer::Transport::corostream - Async DBD::Gofer stream transport using Coro and AnyEvent
SYNOPSIS
DBI_AUTOPROXY="dbi:Gofer:transport=corostream" perl some-perl-script-using-dbi.pl
or
$dsn = ...; # the DSN for the driver and database you want to use
$dbh = DBI->connect("dbi:Gofer:transport=corostream;dsn=$dsn", ...);
DESCRIPTION
The BIG WIN from using Coro is that it enables the use of existing DBI frameworks like DBIx::Class.
KNOWN ISSUES AND LIMITATIONS
- Uses Coro::Select so alters CORE::select globally
Parent class probably needs refactoring to enable a more encapsulated approach.
- Doesn't prevent multiple concurrent requests
Probably just needs a per-connection semaphore
- Coro has many caveats. Caveat emptor.
STATUS
THIS IS CURRENTLY JUST A PROOF-OF-CONCEPT IMPLEMENTATION FOR EXPERIMENTATION.
Please note that I have no plans to develop this code further myself. I'd very much welcome contributions. Interested? Let me know!

Example code:
#!perl
use strict;
use warnings;
use Time::HiRes qw(time);
BEGIN { $ENV{PERL_ANYEVENT_STRICT} = 1; $ENV{PERL_ANYEVENT_VERBOSE} = 1; }
use AnyEvent;
BEGIN { $ENV{DBI_TRACE} = 0; $ENV{DBI_GOFER_TRACE} = 0; $ENV{DBD_GOFER_TRACE} = 0; };
use DBI;
$ENV{DBI_AUTOPROXY} = 'dbi:Gofer:transport=corostream';
my $ticker = AnyEvent->timer( after => 0, interval => 0.1, cb => sub {
warn sprintf "-tick- %.2f
", time
} );
warn "connecting...
";
my $dbh = DBI->connect("dbi:NullP:");
warn "...connected

for (1..3) {
warn "entering DBI...
";
$dbh->do("sleep 0.3"); # pseudo-sql understood by the DBD::NullP driver
warn "...returned
";
}
warn "done.";
Example output:
$ perl corogofer.pl

done. at corogofer.pl line 39.
You can see that the timer callback is firing while the code 'waits' inside the do() method for the response from the database. Normally
that would block.
