如何在不取消正在运行的进程的情况下取消“less”中“ESC-F”的效果？

当我使用 时less，有时我喜欢让事情持续一段时间，所以我使用ESC-F序列键，到目前为止，它可以完成我想要的操作。

我发现返回正常less命令的唯一方法是使用Ctrl-C.但是，当我这样做时，它会停止（取消）正在运行的进程。

我正在寻找一种在不停止正在运行的进程的情况下返回正常less功能的方法，这样我就可以查看一些内容，然后看到以下输出，而无需重新启动我的进程。

有这样的能力吗？

答案1

正确答案是Ctrl+ X。

否则，在管道操作中，如find /var/log -name "*.log" | xargs less, Ctrl+C将终止less并退出以提示。

答案2

从手册页less：

       F      Scroll  forward, and keep trying to read when the end of file is
              reached.  Normally this command would be used  when  already  at
              the  end of the file.  It is a way to monitor the tail of a file
              which is growing while it is being  viewed.   (The  behavior  is
              similar to the "tail -f" command.)

       ESC-F  Like  F,  but  as soon as a line is found which matches the last
              search pattern, the terminal bell is rung and forward  scrolling
              stops.

如果您的标准选项列表（通常在环境变量或文件中less指定，但也可能由 shell 别名或类似定义）包含，则在不退出的情况下不可能停止或函数：$LESS~/.lesskey-KlessFEsc-Fless

       -K or --quit-on-intr
              Causes less to exit immediately (with status 2) when  an  inter‐
              rupt  character  (usually  ^C) is typed.  Normally, an interrupt
              character causes less to stop whatever it is doing and return to
              its  command  prompt.  Note that use of this option makes it im‐
              possible to return to the command prompt from the "F" command.

因为Esc-F是该函数的一个变体F，所以我希望该-K选项也能对其产生相同的效果。
