Common screenshots and Screen recorder tools under Linux

Recording screen:

In Linux commonly used recorder screen tool has 5 kinds, can Baidu or Google under Oh, I choose is recordmydesktop, use is very convenient, the time to pay attention to the number of frames per second high, otherwise the effect is necessarily very poor.

Under Ubuntu you can enter the command to install directly:

Debianlinux users can install the software with the command "sudo apt-get install Recordmydesktopgtk-recordmydesktop", other users will need to download http://on the following website Sourceforge.net/projects/recordmydesktop

：

I choose the Scrot, is also very convenient for a software, debianlinux users with the command "sudo apt-get Installscrot" can be installed.

(The following section turns from: http://forum.ubuntu.org.cn/viewtopic.php?f=50&t=159113)
Scrot is used primarily at the command line, and it uses the IMLIB2 library to fetch and save images. In Ubuntu, you can use the sudo apt-getinstall scrot command to install Scrot. Scrot is used in the format: Scrot [Options][file].
General usage
In general, you can use Scrot to crawl the entire desktop, a specified window, and a rectangular area of the mouse drag selection.

Crawl Desktop: Scrot desktop.png, this command fetches the current entire desktop and saves it as a desktop.png file. This image file can be found in the current directory.
Grab window: scrot-bs window.png, option B allows Scrot to grab the outer frame when the window is crawled, while the S option lets the user choose what window to crawl.
Crawl area: Scrot-s rectangle.png, after this command is executed, the rectangular area dragged by the mouse is Scrot crawled down.
Advanced use
For the normal crawl use Scrot the foundation is enough to cope with. However, in some special cases, using Scrot to grab images requires some skill.

Delay Crawl: SCROT-CD menu.png, the D option in this command is used to delay the capture of the image, followed by 10 for 10 seconds delay, the preceding option C shows the countdown. This technique will fully demonstrate its magic when crawling menus or command prompts.
Generate thumbnails: scrot-t 50% thumb.png, this command generates thumbnails of the image while capturing the image. The option T will turn on this feature, followed by 50% as the scale percentage of the original.
Change quality: Scrot-q quality.jpg, the Q option in this command is used to change the quality of the captured image, which has a value between 1-100 and defaults to 75. The higher the value, the higher the image quality, and the lower the compression rate of the image, the larger the space occupied. PNG format is lossless compression, regardless of your compression level, the image quality is exactly the same (high compression level is only increased point compression time, similar to gzip-9),
So use Scrot-q 1 as much as possible. -Q 1 to-q100 their image quality is exactly the same, but the volume is too poor, so we recommend that you use this format.
Action screenshot: Scrot action.png-e ' mv $f ~/images/', which moves the captured image to the ~/images/directory. Obviously, the function of manipulating the image is turned on by the E option, where the $f represents the path/file name of the original.
The above example specifies the file name of the captured image that needs to be saved. In fact, if you do not specify a name, Scrot automatically uses a combination of the current datetime and width height to generate the file name when the image is crawled.
