如何阻止 VI 重叠并隐藏命令行输出的最后一页？
目前，当我在屏幕内的终端窗口中启动 vi 时，vi 程序会占据全屏并覆盖那里的任何输出历史记录，然后在退出时保留在那里。因此，当稍后向后滚动终端输出时，vi 窗口下的输出被屏蔽。
我目前正在 bashrc 中使用以下别名来解决这个问题...
alias vi='for i in $( seq 1 $LINES );做回声；完毕 ; vi'
到目前为止，这工作得很好，但它让我觉得有点笨拙，我担心我会遇到不可预见的情况，在某些时候它会让我失败。我想知道是否有 vi 或 screen 的命令选项或其他一些更简单、更有效的方法来实现相同的目的。
谢谢。
Currently, when I start vi in a terminal window within screen, the vi program takes up the full screen and covers up any of the output history that was there, and then remains there upon exiting. Thus, when scrolling back through my terminal output at a later time, the output under the vi window is masked.
I'm currently working around this with the following alias in my bashrc...
alias vi='for i in $( seq 1 $LINES ); do echo ; done ; vi'
This has worked just fine so far, but it strikes me as kind of kludgy and I fear I'm going to hit an unforeseen situation where it fails me at some point. I was wondering if there's a command option for either vi or screen or some other simpler, more efficient way of achieving the same.
Thanks.

如果您使用 GNU Screen，.screenrc 中的以下行应该可以解决问题：
这将确保退出 Vi 后恢复旧内容，并且不会再扰乱您的回滚历史记录。
If you use GNU Screen, the following line in your .screenrc should solve the problem:
This will ensure that the old contents is restored after you exit Vi, and it won't clutter your scrollback history anymore.
尝试将
set t_ti= t_te=添加到您的 .vimrc 文件中。要修复也出现此行为的 less，请在 .bashrc 文件中设置
export LESS=-X。注意：某些终端（例如 urxvt）能够通过如下设置为所有 ncurses 程序全局修复此问题：
urxvt*secondaryScreen: falseTry adding
set t_ti= t_te=to your .vimrc file.To fix less which also exhibits this behavior, set
export LESS=-Xin your .bashrc file.Note: Some terminals such as urxvt are able to fix this globally for all ncurses program with a settings like this:
urxvt*secondaryScreen: false
