我在网上搜索了这些信息，发现了不同的命令行，如下所示：
sudo apt-get remove application
sudo apt-get remove application*
sudo apt-get remove --purge application
sudo apt-get remove --purge application*
sudo apt-get purge application
sudo apt-get purge application*
那么，正确的做法是什么呢？有必要使用那个“*”吗？
之后，我还找到了这些命令：
sudo updatedb
sudo locate application
sudo rm -rf (file/folder name)
我对 Linux 很陌生，但在使用它之前，我听说 Windows 程序在卸载后会在硬盘上留下很多残留物，而 Linux 会将其全部删除。
我正在使用 Ubuntu 10.04。要卸载我正在使用的软件包sudo apt-get autoremove application_name或sudo aptitude purge application_name. 最近我安装了 texlive-full 并且由于某些原因我不得不快速卸载它。在我进入终端后updatedb，locate *texlive*输出很长：
maria@marysia-ubuntu:~$ locate *texlive*
