Ubuntu系统下用命令行快速打开各类型文件的方法(xdg-open)
<p><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>在Ubuntu下，通常用命令行打开文本文件，比如用命令gedit、more、cat、vim、less。但当需要打开其他格式文件时，比如pdf、jpg、mp3格式文件，咱们通常做法是进入到文件所在的目录，双击打开，很影响效率。事实上，可以通过命令xdg-open(opens a file or URL in the user's preferred application)打开这些格式文件，甚至是网页，像打开文件一样简单。 </span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>先举两个例子： </span></p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>

代码如下:</p>
</div>
<p class="msgborder" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
