在此之前我先把code写在下面。code中如果你在程序中出现问题就看code前的注意,我在执行时出现以下错误。

1:在我标注红色字体的是最容易出错的地方,因为它直接影响你的捕抓当前窗口的大小,也只有这个地方要你改的,但该起来容易,主要是在分析,看分析这个code?

2:但你按照程序的如入是会出现这个错误,就是“xwininfo 帮助信息”。原因出在哪儿?

3:出错原因就是你的当前终端会话标题,把下面的红色字体,改为你当前终端会话标题,但又不能乱改。怎么改才合理?

4:使用"xwininfo -root -tree" 这个命令,来获取你的当前终端会话窗口,看下面一行,就是我的当前会话id   窗口名   (括号里的你不用管)  WidthxHeight+0+0 +x+y,(其中的x和y就是程序里的了),这样就找到了我的当前会话窗口了,然后把code的红色字体改了你的当前会话名,就可以了。java基础教程

#!/bin/bash

# A simple shell script wrapper to record current terminal session of a linux

# desktop. May work under other Unix like operating systems too.

# Tested on RHEL 6.x, Debian 6.x, and Ubuntu Linux

怎么使用代码?这里我原文里的不翻译了。

Open a terminal.
Open Tab.
Run script as:
./script.sh foo.ogv

Switch to tab # 1 and run your command.
When done switch back to tab #2 and press CTRL + C to save recording to foo.ogv.

To run foo.ogv type:
gnome-open foo.ogv
or
mplayer foo.ogv
