Try:

or

<pre><code>lock() {

 gnome-screensaver-command --lock
}

The second solution allows you to use arguments.

blocks|key|1366173|text|其他答案很好地回答了这个问题，但您的示例看起来第二个命令依赖于第一个命令是否成功退出。您可能希望在您的别名中尝试short-circuit+evaluation：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1366174|alias+lock='gnome-screensaver+&&+gnome-screensaver-command+--lock'|code-block|syntax|javascript|1366175|现在，除非第一个命令成功，否则甚至不会尝试第二个命令。在此SO+question中对短路评估进行了更好的描述。|1366176|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Short-circuit_evaluation|1|https://stackoverflow.com/questions/89154/benefits-of-using-short-circuit-evaluation^0|1K|O|0|0|0|T|B|1|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@$A|V|B|W|1|X]]|C|$]]|$1|D|3|E|5|F|7|Y|8|@]|9|@]|C|$G|H]]|$1|I|3|J|5|6|7|Z|8|@]|9|@$A|10|B|11|1|12]]|C|$]]|$1|K|3|-4|5|6|7|13|8|@]|9|@]|C|$]]]|L|$M|$5|N|O|P|C|$Q|R]]|S|$5|N|O|P|C|$Q|T]]]]

The other answers answer the question adequately, but your example looks like the second command depends on the first one being exiting successfully. You may want to try a <a href="http://en.wikipedia.org/wiki/Short-circuit_evaluation" rel="noreferrer">short-circuit evaluation</a> in your alias: 

<pre><code>alias lock='gnome-screensaver &amp;&amp; gnome-screensaver-command --lock'
</code></pre>

Now the second command will not even be attempted unless the first one is successful. A better description of short-circuit evaluation is described in this <a href="https://stackoverflow.com/questions/89154/benefits-of-using-short-circuit-evaluation">SO question</a>.

blocks|key|1365859|text|这不管用吗？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1365860|alias+whatever='gnome-screensaver+;+gnome-screensaver-command+--lock'|code-block|syntax|javascript|1365861|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|$]]

Does this not work?

<pre><code>alias whatever='gnome-screensaver ; gnome-screensaver-command --lock'
</code></pre>

blocks|key|1581017|text|这将一个接一个地运行两个命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1581018|alias+lock='gnome-screensaver+;+gnome-screensaver-command+--lock'|code-block|syntax|javascript|1581019|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|$]]

This would run the 2 commands one after another:

<pre><code>alias lock='gnome-screensaver ; gnome-screensaver-command --lock'
</code></pre>

blocks|key|1365963|text|所以使用分号：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1365964|alias+lock='gnome-screensaver;+gnome-screen-saver-command+--lock'|code-block|syntax|javascript|1365965|如果您想要为第一个命令提供参数，这将不能很好地工作。或者，在$HOME/bin目录中创建一个简单的脚本。|1365966|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|$]]

So use a semi-colon:

<pre><code>alias lock='gnome-screensaver; gnome-screen-saver-command --lock'
</code></pre>

This doesn't work well if you want to supply arguments to the first command.
Alternatively, create a trivial script in your $HOME/bin directory.

blocks|key|1581367|text|在11年前的讨论中加入我的2分，试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1581368|alias+lock="gnome-screensaver+\gnome-screensaver-command+--lock"|offset|length|style|CODE|1581369|entityMap^0|0|0|1S|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

Adding my 2 cents to the 11 year old discussion try this:

<code>alias lock="gnome-screensaver \gnome-screensaver-command --lock"</code>

<pre><code>function lock() {

The above translated perfectly for me in bash as:
<pre><code>bottom() {

 printf '\n%.0s' {1..100}
}
alias c=&quot;bottom&quot;

<hr />
All I wanted to do was clear the screen (<code>c</code> <a href="/questions/tagged/alias" class="post-tag" title="show questions tagged &#39;alias&#39;" rel="tag">alias</a>) and have the bash prompt appear at the bottom, not top of terminal window. I had solved this long ago (too long ago... forgot what I did), but now I've put the function in .bash_profile and it's off to the races! For now, I am also executing the function so that when I open a new term. window, the prompt, and only the prompt, appears at the bottom. Thanks much for the suggestion. I'm not sure if I just miss this kind of stuff or miss getting paid for it... probably both. :-)

I'd like to define an alias that runs the following two commands consecutively. 

<pre><code>gnome-screensaver
gnome-screensaver-command --lock
</code></pre>

Right now I've added

<pre><code>alias lock='gnome-screensaver-command --lock'
</code></pre>

to my .bashrc but since I lock my workstation so often it would be easier to just type one command.

Multiple commands in an alias for bash

我想定义一个可以连续运行以下两个命令的别名。gnome-screensavergnome-screensaver-command --lock现在我已经添加了alias lock='gnome-screensaver-command --lock'到我的.bashrc，但由于我经常锁定我的工作站，所以只键入一条命令会更容易。
