有一种方法可以删除最右边的列：

# Preview files on the rightmost column?
# And collapse (shrink) the last column if there is nothing to preview?
set preview_files false
set preview_directories false
set collapse_preview true

但是如何删除显示父目录的最左边的列？

我知道我可以set viewmode=multipane用来获取单列。但在这种情况下，当我使用两个选项卡时，我会在同一个屏幕中为两个选项卡获得两列。我希望每个选项卡都有一个屏幕，但我希望每个屏幕都由单列组成。我该如何做到这一点？

我有四个工作区和八个更改工作区的快捷方式。快捷键如下。

工作区快捷方式

我在 Xfce 面板中以 2x2 网格排列了四个工作区，如下所示。

工作区和工作区切换器

即使我可以使用 + 和 + 切换工作区，但我无法Super使用←+Super和+切换工作→区Super↑Super↓

如何再次使用快捷方式切换到上下工作区？

所以，我尝试了以下

xclip -se c -t image/png -i imagefile.jpg

这确实将图像复制到剪贴板，我可以将其粘贴到gimp中，或将其粘贴到新的图像文件中，如下所示。

xclip -se c -t image/png -o > newimage.jpg

但是，当我尝试粘贴以这种方式复制的图像时，我无法将其粘贴到 Facebook Messenger 或帖子中。这是为什么？我该如何解决这个问题？

注意我使用 xfce4-screenshooter，它有一个选项可以将屏幕截图保存到剪贴板。如果我使用它，我可以将该图像数据粘贴到 Facebook Messenger 和帖子中。所以，这一定是我的过程或xclip本身的问题。xfce4-screenshooter 使用什么？

假设我想像以下命令一样进行符号链接：

ln -s /home/user/dots/cmus/cmus.theme /home/user/cmus/cmus.theme

但是要使上述命令起作用，我需要确保该目录/home/user/cmus已经存在。否则会出错。有没有办法解决这个问题mkdir -p？

为了使我的问题清楚，我将放下我的用例。我想创建一个 shell 脚本，它将我的点文件符号链接到适当的位置。到目前为止，我有以下内容：

DIR=$HOME/projects/dotFiles

DOTFILES=(
    "bin"
    ".bashrc"
    ".bash_profile"
    ".gitconfig"
    ".profile"
    ".tmux.conf"
    ".xinitrc"
    ".config/cmus/cmus.theme"
    ".config/compton.conf"
    ".config/dunst"
    ".config/feh"
    ".config/mpv"
    ".config/nvim"
    ".config/ranger"
    ".local/share/fonts"
)

for dotfile in "${DOTFILES[@]}";do
    rm -rf "${HOME}/${dotfile}"
    ln -sf "${DIR}/${dotfile}" "${HOME}/${dotfile}"
done

但是，我不知道如何在不事先明确创建目录的情况下解决我指定的问题。

fzf有一些键绑定，下面列出了其中一些作为示例：

  • Alt-C :cd进入所选目录
  • Ctrl-T ：选择一个文件

我想添加一个键标，以便我可以使用 fzf 启动选定的文件，也许使用xdg-openor mimeopen。

我有一个为我从这个存储库下载的电力线修补的 monaco 字体。现在对于许可问题，此字体没有免费版本。无论如何，我使用 tmuxU+2502作为垂直分割的分隔符。现在，我拥有的 monaco 字体没有这个字形。

我有另一种字体，官方最新版本的Inconsolata，它有一个漂亮的字形版本。不久前我遇到了这篇文章，其中一个答案是使用 fontforge 或类似的字体编辑器手动修补具有该字形的字体。

如何将一个字形从另一种字体添加到一种字体？

我一直在使用以下从终端启动程序：

program_name >/dev/null 2>&1 &

但是最近我遇到了这个网页，推荐了以下方法：

program_name </dev/null &>/dev/null &

现在，我知道第一个是什么意思了。这意味着将stderr 指向stdout 并将stdout 指向/dev/null，即stderr 和stdout 现在都指向null。

但是第二个是什么意思？哪一个更适合从终端无头启动程序？

我正在使用 mupdf-gl，并且使用xprop我没有得到WM_CLASS. 但如果我使用 mupdf-x11，我会得到WM_CLASS.

mupdf-gl 的 xprop 的输出：

bindsym XF86AudioNext exec --no-startup-id playerctl next
bindsym XF86AudioPrev exec --no-startup-id playerctl previous

出于某种原因，一定是由上述配置中的某些原因引起的，当一个窗口变成全屏时，屏幕会随机冻结，但计算机工作正常：声音仍然有效，键绑定有效，我可以用我的键绑定注销，等等。这种情况是随机发生的，即并非每次将窗口设为全屏时，但它主要发生在 chromium-browser 和 mpv 上，主要是在播放视频时（虽然不是 youtube）。

我怎样才能摆脱这个问题？

这是ls -al命令输出：

-rw-rw-r--您可以看到文件权限和文件所有者之间有一个数字enan。该数字是文件的硬链接数。在输出中显示可能对某些情况有用，但现在，我不需要它，有时它会分散我的注意力。你可以看到，我有办法从输出中删除最后修改的日期，ls -al因为我现在不需要它。

那么，如何从ls -al命令输出中删除硬链接的数量？在命令的输出中显示硬链接的数量和最后修改日期的重要性是什么？我的意思是，如果你们中的任何人使用这些信息，请告诉我为什么以及如何这样做，因为我不想无意中影响我应该使用的行为。

默认情况下，tmux 会越过窗格的边缘。例如，假设有两个窗格，pane 1并且pane 2. 假设你在pane 1并且你做到Ctrl+b →了，你在pane 2。如果你再次这样做Ctrl+b →，你会再次在pane 1。如何禁用该功能，所以当我从最后一个窗格导航时，我哪儿也不去？

我有几个具有这些名称的文件：

file1, A.ext  
file1, The.ext

我需要将那里的名称更改为

A file1.ext  
The file1.ext

那就是我需要将文章从末尾移到开头删除逗号。我该怎么做？

我已经研究了 rename 命令，但我没有使用 perl 正则表达式的经验，我想出了这个不起作用的荒谬命令，我离开它是为了显示我的绝望：

rename 's/(?<=[A-Z a-z \s]*),\sA//' *

我最近开始使用cmus 。添加音乐目录后，如果我更改任何音乐文件的任何标签（如专辑名称等），cmus 中的信息不会改变。就算我再做:clear一遍:add ~/Music。如何在 cmus 中刷新此缓存？
