如何在Ruby脚本中向Shell脚本传递含空格的文件名？

我想在Ruby脚本里调用Shell脚本并传递一个带空格的文件名，试了好几种方法都不行，以下是部分尝试：

尝试1：手动转义空格 #

filename = "/Users/gscar/Pictures/_Photo Processing Folders/Watched folder for import to Photos/2024.03.25-16.09.59.gs.O.orf"
filename = filename.gsub(' ', '\ ')
'exiftool -Camera:DriveMode #{filename}'

尝试2：硬编码转义后的路径 #

result = %x{exiftool -Camera:DriveMode /Users/gscar/Pictures/_Photo\ Processing\ Folders/Watched\ folder\ for\ import\ to\ Photos/2024.03.25-16.09.59.gs.O.orf}

执行后提示：

8 files could not be read

尝试3：用引号包裹路径 #

system 'exiftool -Camera:DriveMode "/Users/gscar/Pictures/_Photo Processing Folders/Watched folder for import to Photos/2024.03.25-16.09.59.gs.O.orf"'

执行后无输出。

命令行直接执行正常 #

直接在终端运行以下两种命令都能正常返回结果：

➜ exiftool -Camera:DriveMode "/Users/gscar/Pictures/_Photo Processing Folders/Watched folder for import to Photos/2024.03.25-16.09.59.gs.O.orf"
Drive Mode                      : Single Shot; Electronic shutter

➜ exiftool -Camera:DriveMode /Users/gscar/Pictures/_Photo\ Processing\ Folders/Watched\ folder\ for\ import\ to\ Photos/2024.03.25-16.09.59.gs.O.orf
Drive Mode                      : Single Shot; Electronic shutter

最终尝试的错误代码 #

我想实现的功能类似下面的代码，但执行报错：

filename = "/Users/gscar/Pictures/_Photo Processing Folders/Watched folder for import to Photos/2024.03.25-16.09.59.gs.O.orf"
gsubfilename = filename.gsub(' ', '\ ')
`"exiftool -Camera:DriveMode #{gsubfilename}"`

报错信息：

sh: exiftool -Camera:DriveMode /Users/gscar/Pictures/_Photo\ Processing\ Folders/Watched\ folder\ for\ import\ to\ Photos/2024.03.25-16.09.59.gs.O.orf: No such file or directory

但这条命令在Shell里执行完全正常。

疑问 #

请问问题出在哪里？另外，mini_exiftool似乎无法处理DriveMode字段。
