What do you think about using <code>screen</code> for this? You could run <code>screen</code> via ssh to start the command (<code>concat.sh</code>) and then you'd be able to return to the screen session if you wanted to monitor it (could be handy, depending on what concat does).

To be more specific, try this:

<pre><code>ssh -t $username@$node screen -dm -S testing ./monitor/concat.sh
</code></pre>

You should find that the prompt returns immediately, and that <code>concat.sh</code> is running on the remote machine. I'll explain some of the options:

<ul>
<li><code>ssh -t</code> makes a TTY. screen needs this.</li>
<li><code>screen -dm</code> makes it start in "detached" mode. This is like "background" for your purposes.</li>
<li><code>-S</code> testing gives your screen session a name. It is optional but recommended.</li>
</ul>

Now, once you've done this, you can go to the remote machine and run this:

<pre><code>screen -r testing
</code></pre>

This will attach you to the screen session which contains your program. From there you can control it, kill it, see its output, and so on. Ctrl-A, then d will detach you from the screen session. <code>screen -ls</code> will list all running sessions.

There are some situations when you want to execute/start some scripts on a remote machine/server (which will terminate automatically) and disconnect from the server.

eg: A script running on a box which when executed 

<ol>
<li>takes a model and copies it to a remote server</li>
<li>creates a script for running a simulation with the model and push it to server </li>
<li>starts the script on the server and disconnect </li>
<li>The duty of the script thus started is to run the simulation in the server and once completed (will take days to complete) copy the results back to client.</li>
</ol>

I would use the following command:

<pre><code>ssh remoteserver 'nohup /path/to/script `&lt;/dev/null` &gt;nohup.out 2&gt;&amp;1 &amp;'
</code></pre>

@CKeven, you may put all those commands on one script, push it to the remote server and initiate it as follows:

<pre><code>echo '#!/bin/bash 
rm -rf statuslist 
mkdir statuslist 
chmod u+x ~/monitor/concat.sh 
chmod u+x ~/monitor/script.sh 
nohup ./monitor/concat.sh &amp; 
' &gt; script.sh

chmod u+x script.sh

rsync -azvp script.sh remotehost:/tmp

ssh remotehost '/tmp/script.sh `&lt;/dev/null` &gt;nohup.out 2&gt;&amp;1 &amp;'
</code></pre>

Hope this works ;-)

Edit:
You can also use
ssh user@host 'screen -S SessionName -d -m "/path/to/executable"'

Which creates a detached screen session and runs target command within it

blocks|key|441472|text|对我来说，唯一有效的方法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|441473|screen+-dmS+name+sh+my-script.sh|code-block|syntax|javascript|441474|当然，这取决于屏幕，如果您需要stdin或stdout，您可以稍后进行附加。屏幕将在my-script.sh结束时自行终止。|441475|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

For me, only this worked:

<pre><code>screen -dmS name sh my-script.sh
</code></pre>

This, of course, depends on screen, and lets you attach later, if you ever want stdin or stdout. Screen will terminate itself when my-script.sh ends.

blocks|key|349175|text|下面是一个更常见的决定，需要一些努力才能找到，它对我来说真的很有效：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|349176|#!/usr/bin/bash

theStuff="date;+hostname;+cd+/usr/local;+pwd;+/usr/local/bin/top"

Below is a much more common decision that required some efforts to find, and it really works for me:

<pre><code>#!/usr/bin/bash
theScreenSessionName="test"
theTabNumber="1"
theStuff="date; hostname; cd /usr/local; pwd; /usr/local/bin/top"

echo "this is a test"

ssh -f user@server "/usr/local/bin/screen -x $theScreenSessionName -p $theTabNumber -X stuff \" 
$theStuff
\""
</code></pre>

It sends $theStuff list of commands to the tab No $theTabNumber of the screen session $theScreenSessionName preliminarily created at the 'server' on behalf of 'user'.

Please be aware of a trailing whitespace after
-X stuff \"
that is sent to overcome a 'stuff' option's glitch. The whitespace and $theStuff in the next line are appended by 'Enter' (^M) keystrokes. DON'T MISS 'EM!

The "this is a test" message is echoed in the initial terminal, and $theStuff commands are really executed inside the mentioned screen/tab.

I'm currently trying to ssh into a remote machine and run a script, then leave the node with the script running. Below is my script. However, when it runs, the script is successfully run on the machine but ssh session hangs. What's the problem?

<pre><code>ssh -x $username@$node 'rm -rf statuslist
 mkdir statuslist
 chmod u+x ~/monitor/concat.sh
 chmod u+x ~/monitor/script.sh
 nohup ./monitor/concat.sh &amp;
 exit;'
</code></pre>
