OSX/Linux，降低终端的输出速度 [英] OSX/Linux, slow down the output from terminal

问题描述

我正在打印屏幕上很长的文本文件，该文件在屏幕上滚动得非常快，是否可以减慢滚动速度?换句话说，有一个系统设置可以控制将输出显示到屏幕(OSX/Linux)的速度.

I'm printing to screen a long text file that scrolls very very quickly on my screen, is there a way to slow down the scrolling? In other words is there a system setting that controls the speed at which output is displayed to screen (OSX/Linux).

推荐答案

简单答案:否.

扩展版本:还有其他解决方案.您可以从以下任一选项中进行选择:

Extended version: There are other solutions. You could pick from one of the following:

• 使用管道.使用管道可以重定向终端输出并以自己的速度对其进行检查.适当的符号是|.将输出重定向到诸如less或more之类的程序.两者都允许您通过按回车键滚动显示输出，也可以随时按q退出.例如，要处理较长的目录列表，可以使用

• Use pipes. Using pipes allows you to redirect terminal output and to review it in your own speed. The appropiate symbol is |. Redirect the output to programs like less ore more. Both allow you to scroll through the output via pressing return, you can exit any time by pressing q. For instance, for handling a long directory listing, you could use

ls | more

将输出重定向到文件中.如果您的输出缓存在文件中，则该文件是永久性的，并允许您使用选择的编辑器将其打开以查看(和编辑)它.符号是>.

touch log.txt # create the file
ls > log.txt
nano log.txt # use nano text editor to view

script允许您记录整个终端sessoins.对于您的用例来说，这可能是一个过大的杀伤力，但确实很有用.在手册页中:

script allows you to record entire terminal sessoins. This might be an overkill for your use-case, but is really useful. From the man page:

script为您在终端上打印的所有内容制作一个打字稿.它是 对于需要交互式会议的硬拷贝记录的学生很有用 作为作业证明，因为可以打印出打字稿文件 稍后使用lpr(1).

script makes a typescript of everything printed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr(1).
