+ <p>The <a href="http://web.archive.org/web/20090227001121/http://vicerveza.homeunix.net/%7Eviric/soft/ts/">Task Spooler</a>
+ project allows you to queue up tasks from the shell for batch
+execution. Task Spooler is simple to use and requires no configuration.
+ You can view and edit queued commands, and you can view the output of
+queued commands at any time.</p> </div>
+ <div id="featurecontent" class="xar-align-left">
+ <p>Task Spooler has some similarities with other delayed and batch execution projects, such as "<a href="http://web.archive.org/web/20090227001121/http://ftp.debian.org/debian/pool/main/a/at/">at</a>."
+ While both Task Spooler and at handle multiple queues and allow the
+execution of commands at a later point, the at project handles output
+from commands by emailing the results to the user who queued the
+command, while Task Spooler allows you to get at the results from the
+command line instead. Another major difference is that Task Spooler is
+not aimed at executing commands at a specific time, but rather at simply
+ adding to and executing commands from queues.</p>
+
+<p>The main repositories for Fedora, openSUSE, and Ubuntu do not contain
+ packages for Task Spooler. There are packages for some versions of
+Debian, Ubuntu, and openSUSE 10.x available along with the source code
+on the project's homepage. In this article I'll use a 64-bit Fedora 9
+machine and install version 0.6 of Task Spooler from source. Task
+Spooler does not use autotools to build, so to install it, simply run <code>make; sudo make install</code>. This will install the main Task Spooler command <code>ts</code> and its manual page into /usr/local.</p>
+
+<p>A simple interaction with Task Spooler is shown below. First I add a
+new job to the queue and check the status. As the command is a very
+simple one, it is likely to have been executed immediately. Executing ts
+ by itself with no arguments shows the executing queue, including tasks
+that have completed. I then use <code>ts -c</code> to get at the stdout of the executed command. The <code>-c</code> option uses <code>cat</code> to display the output file for a task. Using <code>ts -i</code> shows you information about the job. To clear finished jobs from the queue, use the <code>ts -C</code> command, not shown in the example.</p>
+
+<pre><div class="code">
+$ ts echo "hello world"
+6
+
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=0/1]
+6 finished /tmp/ts-out.QoKfo9 0 0.00/0.00/0.00 echo hello world
+
+$ ts -c 6
+hello world
+
+$ ts -i 6
+Command: echo hello world
+Enqueue time: Tue Jul 22 14:42:22 2008
+Start time: Tue Jul 22 14:42:22 2008
+End time: Tue Jul 22 14:42:22 2008
+Time run: 0.003336s
+</div></pre>
+
+<p>The <code>-t</code> option operates like <code>tail -f</code>,
+showing you the last few lines of output and continuing to show you any
+new output from the task. If you would like to be notified when a task
+has completed, you can use the <code>-m</code> option to have the
+results mailed to you, or you can queue another command to be executed
+that just performs the notification. For example, I might add a tar
+command and want to know when it has completed. The below commands will
+create a tarball and use <a href="http://web.archive.org/web/20090227001121/http://www.galago-project.org/specs/notification/">libnotify</a>
+ commands to create an inobtrusive popup window on my desktop when the
+tarball creation is complete. The popup will be dismissed automatically
+after a timeout.</p>
+
+<pre><div class="code">
+$ ts tar czvf /tmp/mytarball.tar.gz liberror-2.1.80011
+11
+$ ts notify-send "tarball creation" "the long running tar creation process is complete."
+12
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=0/1]
+11 finished /tmp/ts-out.O6epsS 0 4.64/4.31/0.29 tar czvf /tmp/mytarball.tar.gz liberror-2.1.80011
+12 finished /tmp/ts-out.4KbPSE 0 0.05/0.00/0.02 notify-send tarball creation the long... is complete.
+</div></pre>
+
+<!-- img src="gnome-notify-send.png" -->
+
+<p>Notice in the output above, toward the far right of the header information, the <code>run=0/1</code>
+ line. This tells you that Task Spooler is executing nothing, and can
+possibly execute one task. Task spooler allows you to execute multiple
+tasks at once from your task queue to take advantage of multicore CPUs.
+The <code>-S</code> option allows you to set how many tasks can be executed in parallel from the queue, as shown below.</p>
+
+<pre><div class="code">
+$ ts -S 2
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=0/2]
+6 finished /tmp/ts-out.QoKfo9 0 0.00/0.00/0.00 echo hello world
+</div></pre>
+
+<p>If you have two tasks that you want to execute with Task Spooler but
+one depends on the other having already been executed (and perhaps that
+the previous job has succeeded too) you can handle this by having one
+task wait for the other to complete before executing. This becomes more
+ important on a quad core machine when you might have told Task Spooler
+that it can execute three tasks in parallel. The commands shown below
+create an explicit dependency, making sure that the second command is
+executed only if the first has completed successfully, even when the
+queue allows multiple tasks to be executed. The first command is queued
+normally using <code>ts</code>. I use a subshell to execute the commands by having <code>ts</code> explicitly start a new bash shell. The second command uses the <code>-d</code> option, which tells <code>ts</code>
+ to execute the command only after the successful completion of the last
+ command that was appended to the queue. When I first inspect the queue I
+ can see that the first command (28) is executing. The second command is
+ queued but has not been added to the list of executing tasks because
+Task Spooler is aware that it cannot execute until task 28 is complete.
+The second time I view the queue, both tasks have completed.</p>
+
+<pre><div class="code">
+$ ts bash -c "sleep 10; echo hi"
+28
+$ ts -d echo there
+29
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=1/2]
+28 running /tmp/ts-out.hKqDva bash -c sleep 10; echo hi
+29 queued (file) && echo there
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=0/2]
+28 finished /tmp/ts-out.hKqDva 0 10.01/0.00/0.01 bash -c sleep 10; echo hi
+29 finished /tmp/ts-out.VDtVp7 0 0.00/0.00/0.00 && echo there
+$ cat /tmp/ts-out.hKqDva
+hi
+$ cat /tmp/ts-out.VDtVp7
+there
+</div></pre>
+
+<p>You can also explicitly set dependencies on other tasks as shown below. Because the <code>ts</code>
+ command prints the ID of a new task to the console, the first command
+puts that ID into a shell variable for use in the second command. The
+second command passes the task ID of the first task to ts, telling it to
+ wait for the task with that ID to complete before returning. Because
+this is joined with the command we wish to execute with the <code>&&</code> operation, the second command will execute only if the first one has finished <em>and</em> succeeded.</p>
+
+<p>The first time we view the queue you can see that both tasks are running. The first task will be in the <code>sleep</code> command that we used explicitly to slow down its execution. The second command will be executing <code>ts</code>,
+ which will be waiting for the first task to complete. One downside of
+tracking dependencies this way is that the second command is added to
+the running queue even though it cannot do anything until the first task
+ is complete.</p>
+
+<pre><div class="code">
+$ FIRST_TASKID=`ts bash -c "sleep 10; echo hi"`
+$ ts sh -c "ts -w $FIRST_TASKID && echo there"
+25
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=2/2]
+24 running /tmp/ts-out.La9Gmz bash -c sleep 10; echo hi
+25 running /tmp/ts-out.Zr2n5u sh -c ts -w 24 && echo there
+$ ts
+ID State Output E-Level Times(r/u/s) Command [run=0/2]
+24 finished /tmp/ts-out.La9Gmz 0 10.01/0.00/0.00 bash -c sleep 10; echo hi
+25 finished /tmp/ts-out.Zr2n5u 0 9.47/0.00/0.01 sh -c ts -w 24 && echo there
+$ ts -c 24
+hi
+$ ts -c 25
+there
+</div></pre>
+
+<h4>Wrap-up</h4>
+
+<p>Task Spooler allows you to convert a shell command to a queued command by simply prepending <code>ts</code> to the command line. One major advantage of using ts over something like the <code>at</code> command is that you can effectively run <code>tail -f</code>
+ on the output of a running task and also get at the output of completed
+ tasks from the command line. The utility's ability to execute multiple
+tasks in parallel is very handy if you are running on a multicore CPU.
+Because you can explicitly wait for a task, you can set up very complex
+interactions where you might have several tasks running at once and have
+ jobs that depend on multiple other tasks to complete successfully
+before they can execute.</p>
+
+<p>Because you can make explicitly dependant tasks take up slots in the
+actively running task queue, you can effectively delay the execution of
+the queue until a time of your choosing. For example, if you queue up a
+task that waits for a specific time before returning successfully and
+have a small group of other tasks that are dependent on this first task
+to complete, then no tasks in the queue will execute until the first
+task completes.</p></div>

+ ts - rocks. I'd been doing my batch queuing the hard way
+for 10 years with scripts, 'cron' and 'at'! I discovered 'ts' about a
+month ago. I love that you can limit the number of jobs to any number
+(like the number of cores your system has) OR have different queues
+based on FIFOs or environment variables OR ... the options are nearly
+endless.<br>
+<br>
+Or just use the default settings let 'er rip with smart defaults.<br>
+<br>
+Anyone with a PVR/MythTV box who wants to convert content from MPG2 to
+MPG4, but not overtax their system can use 'nice' and 'ts' to get there
+easily.
