sudo mkdir /New_Location/Program-Files/Java # Generates New Program Directory
sudo cp -a /usr/lib/jvm/* /New_Location/Program-Files/Java # Moves Program to new folder
sudo rm -rf /usr/lib/jvm # Removes opt directory
sudo ln -s /New_Location/Program-Files/Java /usr/lib/jvm # Creates Symbolic Link
此时最好重新启动，这应该会清除缓存。
Best way I can think of is to use a symbolic link
note that not all programmes are installed to the same directory and /opt may not be the best thing to move. (see end for example of moving only one folder/program)
This is what I did with EasyPeasy (Ubuntu 10.04)
Follow this code carefully some of the commands can delete important files if used incorrectly.
First you need to make sure /opt (or your distros default apt-get install directory) is empty. If you have data in the opt folder, which you most likely do, you can move it to somewhere else first for safe keeping:
sudo mkdir /New_Location/newtmp # Generates Temporary Folder for Programs
sudo cp -a /opt/* /New_Location/newtmp # Moves Programs to Temp folder
Once backed up you can remove the original directory:
sudo rm -rf /opt/ # Removes opt directory
You can then create your new Program Files folder in a drive with lots of space and create a symbolic link:
sudo mkdir /New_Location/Program-Files # Generates New Program Directory
sudo ln -s /New_Location/Program-Files /opt # Creates Symbolic Link
Finally move all your old program files to your new folder and clean up the temporary data:
sudo cp -a /New_Location/newtmp/* /New_Location/Program-Files # Moves Programs to Program Files Folder
sudo rm -rf /New_Location/newtmp/ # Removes Temp folder
If you only wanted to move a single program which is taking up a hunk of your space you could use the same process.
eg: to move Java (JVM approx 300MB) do the following. check directory of java using disk usage analyser. mine is /usr/lib/jvm
sudo mkdir /New_Location/Program-Files/Java # Generates New Program Directory
sudo cp -a /usr/lib/jvm/* /New_Location/Program-Files/Java # Moves Program to new folder
sudo rm -rf /usr/lib/jvm # Removes opt directory
sudo ln -s /New_Location/Program-Files/Java /usr/lib/jvm # Creates Symbolic Link
Its best at this point to do a restart which should clear the cache.
You can't: the installation path is hard-coded in packages (see for example: http://packages.ubuntu.com/oneiric/i386/mono-runtime/filelist). This path is usually /usr instead of /opt, but it depends of the packages. If you want to override the default directory, you must extract manually the content of the packages. But, it can not work: config files, even binary files sometimes, will continue to use the old path. So you must update them in order for the packages to work correctly.

我能想到的最好方法是使用符号链接
，请注意，并非所有程序都安装到同一目录，并且 /opt 可能不是最好的移动方式。 （请参阅末尾，了解仅移动一个文件夹/程序的示例）
这是我使用 EasyPeasy (Ubuntu 10.04) 所做的
。请仔细遵循此代码，如果使用不正确，某些命令可能会删除重要文件。
首先，您需要确保 /opt （或您的发行版默认 apt-get 安装目录）为空。如果您的 opt 文件夹中有数据（您很可能这样做），您可以先将其移动到其他位置以进行安全保存：
备份后，您可以删除原始目录：
然后您可以在驱动器中创建新的 Program Files 文件夹大量空间并创建符号链接：
最后将所有旧程序文件移动到新文件夹并清理临时数据：
如果您只想移动一个占用大量空间的程序，您可以使用相同的方法过程。
例如：
要移动 Java（JVM 约 300MB），请执行以下操作。
使用磁盘使用分析器检查 java 目录。
我的是 /usr/lib/jvm
此时最好重新启动，这应该会清除缓存。

你不能：安装路径是硬编码在包中的（例如： http://packages.ubuntu.com/oneiric/i386/mono-runtime/filelist）。该路径通常是 /usr 而不是 /opt，但这取决于软件包。如果要覆盖默认目录，则必须手动提取包的内容。但是，它无法工作：配置文件，有时甚至是二进制文件，将继续使用旧路径。因此，您必须更新它们才能使软件包正常工作。
