Linux(Ubuntu) Terminal-how to view previous pages not visible anymore
提问by Namratha
When you scroll up, say to see a log, the first portion of it will not be visible since the terminal only supports a limited no. of lines. So if you want to scroll up and be able to see everything, at least a few pages up, how do you do it?
当您向上滚动时，比如说要查看日志，它的第一部分将不可见，因为终端仅支持有限的编号。行。因此，如果您想向上滚动并能够看到所有内容，至少向上翻几页，您会怎么做？

An alternative to screen is using tee to copy all output to a file while still printing it on the terminal:
screen 的替代方法是使用 tee 将所有输出复制到文件中，同时仍将其打印在终端上：
yourcommand | tee output.txt

If you are using gnome-term (the default), then you can change your settings. Either set the no. of lines to unlimited, or to a much larger buffer size than the default.
如果您使用 gnome-term（默认），那么您可以更改您的设置。要么设置号。行数为无限制，或比默认值大得多的缓冲区大小。

You can enable unlimited scroll back (or a huge amount if you want).
您可以启用无限回滚（或大量回滚，如果您愿意）。
To do this, go to
为此，请访问
File → Profile preferences → Scrolling [tab]
文件 → 配置文件首选项 → 滚动 [标签]
Then, check Unlimited, or set the number of lines desired. And of course, it only applies to the next typed lines.
然后，检查Unlimited或设置所需的行数。当然，它只适用于下一个键入的行。
