То, что Вы хотите, является неинтерактивной очередью команды. Хорошие новости! Я записал один для Вас.

enqueue_cmd:

#!/usr/bin/perl -w

# Enqueue a job

use strict;

use Fcntl qw(:flock);

my $JOB_QUEUE_FILE = '/var/tmp/job_queue';
my $LOCK_TRIES = 5;
my $LOCK_SLEEP = 1;

my $jq;
open $jq, ">> $JOB_QUEUE_FILE" or die "!open $JOB_QUEUE_FILE: $!";

my $locked = 0;

LOCK_ATTEMPT: for (my $lock_tries = 0; $lock_tries < $LOCK_TRIES;
    $lock_tries++)
{
    if (flock $jq, LOCK_EX) {
            $locked = 1;
            last LOCK_ATTEMPT;
    }

    sleep $LOCK_SLEEP;
}

$locked or die "could not lock $JOB_QUEUE_FILE";

for (@ARGV) {
    print $jq "$_\n";
}

close $jq;

dequeue_cmd:

#!/usr/bin/perl -w

# Dequeue a jobs and run them

use strict;

use Fcntl qw(:seek :flock);
use FileHandle;

my $QUEUE_FILE = '/var/tmp/job_queue';
my $OUTPUT_FILE = '/var/tmp/job_out';
my $LOCK_TRIES = 5;
my $LOCK_SLEEP = 1;
my $JOB_SLEEP = 1;

my $locked;

my $jo;
open $jo, ">> $OUTPUT_FILE" or die "!open $OUTPUT_FILE: $!";
$jo->autoflush(1);

my $jq;
open $jq, "+< $QUEUE_FILE" or die "!open $QUEUE_FILE: $!";

my @jobs = ( );
my $job;

JOB: while (1) {

    if (-s $QUEUE_FILE == 0) {
            sleep $JOB_SLEEP;
            next JOB;
    }

    $locked = 0    

    LOCK_ATTEMPT: for (my $lock_tries = 0; $lock_tries < $LOCK_TRIES;
            $lock_tries++)
    {
            if (flock $jq, LOCK_EX) {
                    $locked = 1;
                    last LOCK_ATTEMPT;
            }

            sleep $LOCK_SLEEP;
    }
    $locked or die "could not lock $QUEUE_FILE";

    seek $jq, 0, SEEK_SET or die "could not seek to start of file";

    push @jobs, <$jq>;

    truncate $jq, 0 or die "could not truncate $QUEUE_FILE";
    seek $jq, 0, SEEK_SET or die "could not seek to start of $QUEUE_FILE";

    flock $jq, LOCK_UN;

    for $job (@jobs) {
            chomp $job;
            print $jo "## executing $job\n";
            print $jo `$job`;
    }

    sleep $JOB_SLEEP;
}

Во-первых, выполненный nohup ./dequeue_cmd &, Затем добавьте свои команды как так:

./enqueue_cmd "echo 'hello world'" "sleep 5" "date"
./enqueue_cmd "ls /var/tmp"

Вывод появляется в /var/tmp/job_out:

tail -F /var/tmp/job_out
## executing echo 'hello world'
hello world
## executing sleep 5
## executing date
Fri Dec 10 16:35:43 PST 2010
## executing ls /var/tmp
ff
job_out
job_queue
ss
