合并视频和字幕然后删除现有文件的脚本（非递归）
Sum*_*ukh 7 command-line video nautilus-script
我一直在使用mkvmerge合并视频文件和字幕，我正在使用以下命令
mkvmerge -o output.mkv video.mp4 subtitles.srt
哪个工作正常，但您可能会猜到这真的很慢
- 我必须在存储电影的每个目录中打开终端。
- 然后我必须在命令中复制并粘贴文件的名称
- 然后我必须重命名输出文件
- 然后删除我使用的原始文件
这是一个漫长的过程。
我想要的理想情况。
- 我将进入包含同名电影文件和字幕文件的文件夹。
- 我选择一个电影文件和一个字幕文件，右键单击并在它们上运行 nautilus 脚本。
- 他们合并了
- 原始文件被删除。
- 使用带有
mkv扩展名的原始文件的名称重命名合并的文件
这不需要递归，我不希望我的硬盘创建和删除 100 个文件。电影文件和字幕文件通常具有相同的名称，但有时会在字幕文件中固定“_en”后缀。如果您有其他方法可以做到这一点，我也同意。
我决定获得一些使用 Bash 的经验并编写了以下脚本，该脚本具有以下功能：
- 它可以处理所有文件和文件夹，放入当前目录。
- 如果有多个字幕或视频文件（示例文件除外），脚本将要求手动交互。
- 在所有其他情况下，脚本会自动将所有文件和文件夹移动到备份目录（请注意运行它的位置！），该目录将移动到用户的垃圾文件夹中，而不是被删除。
- 它可以处理多种类型的视频和字幕扩展。
- 它用于
mkvmerge将视频与字幕文件合并，也用于notify-send在 GUI 中显示一些消息。它还用于gvfs-trash移动用户垃圾文件夹中的文件。 - 它可以用作Nautilus 脚本或常规 shell 脚本，但需要 GIU 环境，而
notify-send命令存在于脚本主体中。 - 输出文件的名称可以基于目录名称（默认）或源视频文件的名称。
- 此外，当仅选择两个文件（一个视频和一个字幕文件）时，它们将被合并，文件夹的其余内容将被保留。输出文件将以源视频文件命名。此选项仅在脚本用作 Nautilus 脚本时可用。

设置：
创建可执行文件并将上述内容粘贴到其中。让我们调用这个文件
merge-video-sub：
Run Code Online (Sandbox Code Playgroud)touch merge-video-sub chmod +x merge-video-sub nano merge-video-subln -s将此文件复制（或）到文件夹中~/.local/share/nautilus/scripts，使其可用作当前用户的 Nautilus 脚本。目前我找不到如何使它在系统范围内作为 Nautilus 脚本可用的方法。
将文件复制到
~/bin（并添加export PATH=$PATH:~/bin到~/.bashrcif的底部）以使其可用作当前用户的 shell 命令。将文件复制到其中
/usr/local/bin以使其可用作 shell 命令系统范围。简短的方法是
curl将脚本从我的 PasteBin直接放入nautilus/scripts文件夹：
Run Code Online (Sandbox Code Playgroud)curl https://pastebin.com/raw/HrLTibuR | sed -e 's/\r$//' > $HOME/.local/share/nautilus/scripts/merge-video-sub chmod +x $HOME/.local/share/nautilus/scripts/merge-video-sub
