仅控制台环境中 CentOS 缓冲区/剪贴板的使用

我有 CentOS 8 最小安装。没有图形用户界面。如果我在控制台上，假设我已经输入了一条命令，例如nice-command-with-switches-that-does-stuff我满意的命令。现在，我想选择控制台上的该行的全部或部分，以便我可以vi script.sh将此信息粘贴到脚本中我想要的位置。

显然，做echo 'nice-command-with-switches-that-does-stuff' >> script.sh可以工作，但前提是我想要文件末尾的文本（但情况并非总是如此）。

有没有一种通用的方法可以让我有选择地在我正在工作的控制台上标记一些文本并将其存储在缓冲区/剪贴板中以在其他地方使用（例如在内部vim或nano其他编辑器中），并且在相反的方向上，我可以猛拉vi 内部的一些文本，然后我可以保留这些文本，直到我在 vi 外部提取然后将其粘贴到控制台上？

答案1

  • 您可以选择屏幕上的文本，然后通过 gpm 服务使用鼠标复制/粘贴它。我不确定它是否默认启用，如果不是，dnf install gpm; systemctl enable gpm; systemctl start gpm.

  • 其次，您可以使用screen/tmux复制屏幕的任何部分（包括回滚历史记录），然后粘贴到您想要的任何位置。

可能还有其他方法，但这两种方法是最明显的。纯 Linux 文本终端的功能非常有限。
