Also, if you don't want to have a script available on the remote server, try the following:

<pre><code>ssh thehost 'cd /tmp; ls; echo Hello world, I am `hostname`'
</code></pre>

and for SCP-less copying:

<pre><code>ssh localhost 'cat /bin/bash' &gt; local_bash

blocks|key|4077801|text|如果您的目标仅是传输文件，则应使用scp。但是，要在远程主机上执行一些命令而不在该远程主机上使用特定脚本，您可以简单地使用如下所示的标准输入：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4077802|!/bin/sh

If your goal is only to transfer files, you should use scp. But to execute some commands on the remote host without having a specific script on that remote host, you can simply use the stdin like this:

<pre><code>!/bin/sh
ssh -o PreferredAuthentications=publickey brjones@server.com &lt;&lt; EOT
cd ~/folder
echo "hello" &gt; hello.txt

You should use <code>ssh</code> in this way to execute scripts on remote machines,

<pre><code>ssh user@server exec /path/to/script/script.sh
</code></pre>

where <code>script.sh</code> is available on the server on the given path from the <code>user</code> login.

<hr>

If the script is not present on the server but available on your local machine (and you do not have common NFS shared space between the two machines), you should send the script with <code>scp</code> like this,

<pre><code>scp script.sh user@server:/path/to/script/
</code></pre>

<hr>

Now, for your specific case of getting a server file you should just execute,

<pre><code>scp user@server:/path/to/file/filename .
</code></pre>

like some other answers already suggest.

blocks|key|1604439|text|脚本中的ssh不是这样工作的。但是，它确实能够通过将命令指定为ssh的参数来在远程服务器上执行命令，例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1604440|ssh+brjones@server.com+do_foo.sh|1604441|将在服务器上运行do_foo.sh脚本|1604442|然而，对于您的情况，看起来您真正想要的是SCP。|1604443|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

ssh in a script doesn't work like that. However it does have the capability to execute a command on a remote server by specifying the command as an argument to ssh, like:

ssh brjones@server.com do_foo.sh

will run the do_foo.sh script on the server

However for your situation it looks like what you are really looking for is SCP.

blocks|key|4077878|text|除了铁门的回答之外，当然你还可以通过以下命令从你的本地脚本中输入命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4077879|ssh+thehost+<+commands.sh|code-block|syntax|javascript|4077880|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In addition to the answer by Tiemen, of course you can pipe the commands from your local script with:

<pre><code>ssh thehost &lt; commands.sh
</code></pre>

scp? Remote is an appliance with a read only file system. I don't want to leave the script behind, or use multiple invocations of ssh to clean it up after or multiple invocations to execute it one line at a time. The list goes on...

<a href="https://stackoverflow.com/questions/305035/how-to-use-ssh-to-run-shell-script-on-a-remote-machine">great solution here by Yarek T:</a>

You might have to play around a bit with quoting or escapes but it gets the job done, with a single connection to the remote and the script remaining local.

If you want to invoke a script on remote host, which present on localhost

<code>ssh remote Password@remoteHostname &lt; localScript.sh</code>

If you want to invoke a script which is already on remote host

<code>ssh remote Password@remoteHostname "$PATH_OF_SCRIPT/remoteScript.sh"</code>

I would like to create a script that automatically logs into a remote server and grabs a file on the server. The script already logs into the server however the commands are not run on that machine. Once I disconnect from the remote server, the commands are run on the client machine. 

<pre><code>!/bin/sh
ssh -o PreferredAuthentications=publickey brjones@server.com
cd ~/folder
"i would like to grab file and copy it to client machines folder"
</code></pre>

EDIT: I am not sure if you noticed but I am used a passwordless connection to the remote server using ssh and keygeneration. I appreciate the ideas but I am looking to possibly pipe commands or run commands on the remote server with the script on the client. I realize that the remote server does not have access to the client script, however I was curious if it was possible to pipe the commands through the ssh connection.
