<p>All commandline applications shipped with Haiku are in <span class="path">/boot/system/bin/</span>. Your own or additionally installed commandline apps will appear there as well, or in <span class="path">~/config/bin/</span>, when installed from a .hpkg package. Otherwise you can put them into <span class="path">/boot/system/non-packaged/bin/</span> or <span class="path">~/config/non-packaged/bin/</span>. All these locations are part of the PATH variable and are therefore automatically found.<br />
|
||
The following isn't an exhaustive list of all Haiku-specific CLI apps, it serves just to highlight a few of the most useful to give you a taste. Feel encouraged to explore what's in the <span class="path">bin/</span> folders on your own a bit. Executing an app with the parameter <tt>--help</tt> shows the usage of the command and all its various options.</p>

|
||
<p>这些命令用于显示，读取，添加和删除文件的属性；需要注意的是，这些元数据仅仅可用于BFS格式的磁盘和分区，而且移动文件到其他的文件系统将会把其相关的属性移除！<br />
|
||
上面的命令在<a href="../attributes.html#attributes-terminal">终端中的属性</a>会有相关的描述。</p>

|

<p>利用这些命令，您可以对BFS的索引属性进行排序，新建，重新索引和删除等操作。由于每个卷都有自己独立的索引，所以在不同的卷之间拷贝文件时尤其要注意。<br />上述这些命令在<a href="../index.html">索引</a>主题中会有详细的描述。</p>

|

<p>The <span class="cli">package</span> command is used to manage HPKG packages. Have a look at the article <a href="https://www.haiku-os.org/guides/daily-tasks/install-applications">Installing applications</a> to learn the very basics. Usually the tool <a href="https://github.com/haikuports/haikuports/wiki">haikuporter</a> is used to create so-called recipes for automatic package building.</p>
|
||
<p><span class="cli">pkgman</span> is used to search, install, update and uninstall packages. Package repositories can be added, dropped and their package lists refreshed. A special kind of update is invoked with the parameter <tt>full-sync</tt>: It is more aggressive and also downgrades or removes packages, if necessary.<br />
|
||
For more details on a parameter, append "--help", e.g. <tt>pkgman search --help</tt>.</p>

<td valign="top"><p><span class="cli">alert</span> 该命令将会打开一个带有预定义图标，说明注记和三个按钮的典型警示窗口，并且在终端中返回已选中按钮的标题和退出状态（以0开始）。例如，下面就是一个例子：</p>
|

<pre class="terminal">alert --idea "FantasticApp(tm) installed successfully!

<td valign="top"><p>The launch_daemon starts all sorts of services and applications at boot-up. For some it was instructed to re-start them if they were quit. If you don't want that – maybe you'd like to test a modified Tracker, for example – you use <span class="cli">launch_roster</span> to <tt>stop</tt> the re-starting of the application before quitting it. Similarly, you can <tt>start</tt> it again or get <tt>info</tt> about it. Without parameter, <span class="cli">launch_roster</span> lists all apps/services that are under its control.<br />
|

For example, this will stop the re-launching of the Deskbar:</p>
|

<pre class="terminal">launch_roster stop x-vnd.be-tskb</pre>

<td valign="top"><p><span class="cli">mountvolume</span> is preferred by many to mount local partitions and disks, because its usage is so easy: just call it with the name of the partition and you're done. Try <tt>--help</tt> for more options.</p>
|
||
<p><span class="cli">mount</span> can additionally mount remote disks by using a network filesystem, like NFS4. You specify the used filesystem with the <tt>-t</tt> parameter and the remote location with the <tt>-p</tt> parameter. As filesystem parameter you can use anything you find in <span class="path">/system/add-ons/kernel/file_system</span> (and corresponding file hierarchies under <span class="path">~/config</span> or "<span class="path">non-packaged</span>", of course). You also have to create a folder as mountpoint. Here's an example:</p>
|
||
<pre class="terminal">mkdir -p /DiskStation
|
||
mount -t nfs4 -p "192.168.178.3:volume1" /DiskStation</pre></td></tr>

|

<td valign="top"><p><span class="cli">open</span>是一个非常小巧的工具。通过它，您可以以默认的程序打开任何文件，或者利用程序的签名还打开该程序而无需知道它的路径。它也可以用于打开网页，甚至“虚拟” 的目录， <tt>.</tt> 用于当前目录或者 <tt>..</tt> 用于上层目录，并且可以在 Tracker 中打开相应的文件夹。</p>
|
||
</td></tr>
|
||
<tr><td><p><span class="cli">ramdisk</span></p></td><td style="width:10px;"> </td>
|
||
<td valign="top"><p>A ramdisk is like a harddisk running only in the computer's memory. That makes it very fast but also volatile, because its contents vanishes when you shut down the computer, or it crashes or you experience a blackout.<br />
|
||
To create a ramdisk of 1 GiB, format to the name "RAMses" and mount it, you enter this in Terminal or create a script of it:</p>
|
||
<pre class="terminal">ramdisk create -s 1gb
|
||
mkfs -q -t bfs /dev/disk/virtual/ram/0/raw RAMses
|
||
mountvolume RAMses</pre>
|
||
<p>Note: When creating a ramdisk, the <span class="cli">ramdisk</span> command prints out the path to it. If you create several disks, that path <span class="path">/dev/disk/virtual/ram/0/raw</span> will change!</p>
|
||
<p>To preserve the contents, at least if no calamity like a blackout etc. strikes, a ramdisk can be set up to read/write an image on the harddisk. For that, you need to supply a file of the desired size that will be read from every time you start your ramdisk, and written to when you unmount it. To create an image file "RAMimage" of 500MiB and format it, do this:</p>
|
||
<pre class="terminal">dd if=/dev/zero of=RAMimage bs=500M count=1
|
||
mkfs -q -t bfs /dev/disk/virtual/ram/0/raw RAMimage</pre>
|
||
<p>From now on, you start the ramdisk like this:</p>
|
||
<pre class="terminal">ramdisk create RAMimage
|
||
mountvolume RAMimage</pre>
|
||
<p>It's very important to always cleanly unmount you ramdisk, either from Tracker or with <span class="cli">unmount /RAMimage</span>, or the changes won't be written back to the image file!</p>
