本文主要记录一些自己在Ubuntu系统下用到的小技巧，希望能对大家能有帮助。
1.终端命令补全时忽略大小写敏感
$echo "set completion-ignore-case on">>~/.inputrc，然后重启终端即可生效。
2.添加快捷方式到启动器（以Eclipse为例）
新建快捷方式的配置文件：$sudo gedit /usr/share/applications/eclipse.desktop
配置内容如下，其中Icon和Exec属性分别是应用图标和可执行程序所在的路径，其他属性根据自己需要自行配置即可。
[Desktop Entry]Encoding=UTF-8Name=eclipseComment=Eclipse IDEIcon=/usr/local/adt-bundle/eclipse/icon.xpmExec=/usr/local/adt-bundle/eclipse/eclipseTerminal=falseStartupNotify=trueType=ApplicationCategories=Development;IDE;Java;
配置文件生成以后，点击Ubuntu左上方的“Dash 主页”按钮，在弹出的窗口中即可搜索到新添加的快捷方式。点击快捷方式打开应用以后，右键快捷方式，选中“锁定到启动器”，即可将该快捷方式锁定到启动器中。
3. 推荐几个国内的高速更新源
