Gnome-Terminal 中是否有命令,或者任何可选项卡式 shell 可以打开新选项卡?

Gnome-Terminal 中是否有命令,或者任何可选项卡式 shell 可以打开新选项卡?

我并不是在寻找键盘快捷键,而是想要以下命令:

  • 新窗户
  • 新标签
  • 关闭当前标签或窗口
  • 最大化 Shell 窗口
  • 最小化 Shell 窗口
  • 将 Shell 移至其他工作空间
  • 切换标签

基本上就是类似这样的操作。记住,我不需要快捷方式,而是需要实际的命令。这样做的原因是我可以利用别名功能。

答案1

默认情况下,您无法在 Gnome-Terminal 中执行此操作,至少使用原始命令不行。

但是,您可以编写脚本来调用可以执行此操作的键盘快捷键。请注意,您需要xdotoolsudo apt install xdotool

  • 新窗户:使用 启动一个新的终端窗口nw
    我们只需 就可以做到这一点gnome-terminal
    添加.bashrc

    echo "alias nw=gnome-terminal" >> ~/.bashrc
    
  • 新标签:使用启动新标签页nt
    我们可以使用xdotool getactivewindow $(xdotool key ctrl+shift+t)
    添加.bashrc

    echo "alias nt='xdotool getactivewindow $(xdotool key ctrl+shift+t)'" >> .bashrc
    
  • 关闭标签:再次点击关闭当前选项卡或窗口ct
    xdotoolxdotool getactivewindow $(xdotool key ctrl+shift+w)
    添加.bashrc

    echo "alias ct='xdotool getactivewindow $(xdotool key ctrl+shift+w)'" >> .bashrc
    
  • 最大化窗口:最大化整个窗口maw
    我们可以wmctrl在这里使用:wmctrl -r :ACTIVE: -b toggle,maximized_vert,maximized_horz
    添加.bashrc

    echo "alias maw='wmctrl -r :ACTIVE: -b toggle,maximized_vert,maximized_horz'" >> .bashrc
    
  • 最小化窗口:最小化整个窗口miw
    我们可以再次使用xdotoolxdotool windowminimize $(xdotool getactivewindow)
    添加.bashrc

    echo "alias miw='xdotool windowminimize $(xdotool getactivewindow)'" >> .bashrc
    
  • 移至工作区mtw <id>
    :使用以下命令将窗口移动到另一个工作区:仅仅在 shell 脚本中是不可能实现的,而且远远超出了我的个人经验。我建议使用 Serg 的脚本来实现这个目的,因为它现在确实有效。啊,Compiz 的好处。

介绍

本答案中提供的脚本允许用户通过一个命令和选项列表来控制其终端窗口。它使用简单,并且与任何具有类似键绑定的终端仿真器兼容gnome-terminal。移动选项也可以用于其他终端,但不保证这些终端可以打开选项卡。

该脚本涵盖了标签页打开、窗口打开、向下移动到工作区、向右移动到工作区、通过整数引用的特定工作区、最小化、最大化和取消最大化窗口。该脚本唯一没有涵盖的是关闭标签页/窗口,因为每个 shell/终端仿真器已经有了相应的命令 -exit或者通过CtrlD快捷方式。

!!!注意:您需要xdotool切换工作区和打开标签页。通过 安装sudo apt-get install xdotool。如果您不想安装额外的软件包,请记住工作区和标签页切换不起作用,但其他选项则会。

用法:

的所有参数windowctrl.py都是可选的,因此它们可以单独使用,也可以一起使用。如-h选项所示。

$ ./windowctrl.py -h                                                                               
usage: windowctrl.py [-h] [-w] [-t] [-m] [-M] [-u] [-v VIEWPORT] [-r] [-d]

    Window control for terminal emulators. Originally written
    for gnome-terminal under Ubuntu with Unity desktop but can 
    be used with any other terminal emulator that conforms to 
    gnome-terminal keybindings. It can potentially be used for 
    controlling other windows as well via binding this script
    to a keyboard shortcut.

    Note that --viewport and --tab options require xdotool to be
    installed on the system. If you don't have it installed, you 
    can still use the other options. xdotool can be installed via
    sudo apt-get install xdotool.


optional arguments:
  -h, --help            show this help message and exit
  -w, --window          spawns new window
  -t, --tab             spawns new tab
  -m, --minimize        minimizes current window
  -M, --maximize        maximizes window
  -u, --unmaximize      unmaximizes window
  -v VIEWPORT, --viewport VIEWPORT
                        send window to workspace number
  -r, --right           send window to workspace right
  -d, --down            send window to workspace down

补充说明

  • 您问“Gnome-Terminal 中是否有命令,或者是否有任何可选项卡的 shell 可以打开新选项卡?” Gnome Terminal 手册没有列出这样的选项。shell 是命令行实用程序。选项卡是 GUI 应用程序的功能。有终端多路复用器,如screen或 ,tmux它们可以有“选项卡”或分割窗口,这有点接近“可选项卡的 shell”,但这不是您问的同一类型的行为。基本上,您的问题的答案是“否”。总是有替代方案,我的答案提供了其中之一。它根据终端窗口的性质来处理它 - X11 GUI 窗口。

  • 这个答案与别名有什么关系?嗯,首先别名可能有点混乱,特别是在引用和解析来自多个命令的多个输出时。此脚本为您提供了一个集中的命令,带有标志/开关,可在窗口上执行离散任务。它还使别名更简单。您可以这样做alias nw='windowctrl.py --window'。更短,更整洁。
