折腾：
期间，去试试用mongofiles去删除文件。
delete <filename>
Delete the specified file from GridFS storage.
-》如果两个文件名一样，会有啥现象？
mongodb gridfs delete file
mongofiles delete file
“delete <filename>
Delete the specified file from GridFS storage.
delete_id “<ObjectId>”
New in version 3.2.0.
Delete the specified file from GridFS storage. Specify the file using its _id.”
去试试
➜ 英语资源 mongofiles -d gridfs delete "Otto the Cat.MP3" 2018-03-29T10:16:14.924+0800 connected to: localhost successfully deleted all instances of 'Otto the Cat.MP3' from GridFS
效果：
把名字是：
“Otto the Cat.MP3”
的删除掉了：
> db.fs.files.find().pretty()
{

"chunkSize" : 261120,
"uploadDate" : ISODate("2018-03-28T06:43:08.613Z"),
"length" : 8338105,

}
{
"_id" : ObjectId("5abb5fcaa4bc711531cee35c"),
"chunkSize" : 261120,
"uploadDate" : ISODate("2018-03-28T09:26:35.121Z"),
"length" : 8338105,
"md5" : "b7660d833085e9e1a21813e4d74b0cc3",
"filename" : "/Users/crifan/dev/dev_root/company/xxx/数据/FromMaggie/英语资源/All Aboard Reading/音频/Otto the Cat.MP3"
}
{
"_id" : ObjectId("5abb6194a4bc71165f9f49f5"),
"chunkSize" : 261120,
"uploadDate" : ISODate("2018-03-28T09:34:12.537Z"),
"length" : 8338105,
"md5" : "b7660d833085e9e1a21813e4d74b0cc3",
"filename" : "Otto the Cat"
}
{
"_id" : ObjectId("5abc43a4a4bc712159a35cd9"),
"chunkSize" : 261120,
"uploadDate" : ISODate("2018-03-29T01:38:44.853Z"),
"length" : 8338105,
"md5" : "b7660d833085e9e1a21813e4d74b0cc3",
"filename" : "Otto the Cat-withMIME.MP3",
"contentType" : "audio/mpeg"
}然后再去，找2个文件名一样的去删除试试：
➜ 英语资源 mongofiles -d gridfs delete "/Users/crifan/dev/dev_root/company/xxx/数据/FromMaggie/英语资源/All Aboard Reading/音频/Otto the Cat.MP3" 2018-03-29T10:17:40.879+0800 connected to: localhost successfully deleted all instances of '/Users/crifan/dev/dev_root/company/xxx/数据/FromMaggie/英语资源/All Aboard Reading/音频/Otto the Cat.MP3' from GridFS
结果：
> db.fs.files.find().pretty()
{
"_id" : ObjectId("5abb6194a4bc71165f9f49f5"),
"chunkSize" : 261120,
"uploadDate" : ISODate("2018-03-28T09:34:12.537Z"),
"length" : 8338105,
"md5" : "b7660d833085e9e1a21813e4d74b0cc3",
"filename" : "Otto the Cat"
}
{
"_id" : ObjectId("5abc43a4a4bc712159a35cd9"),
"chunkSize" : 261120,
"uploadDate" : ISODate("2018-03-29T01:38:44.853Z"),
"length" : 8338105,
"md5" : "b7660d833085e9e1a21813e4d74b0cc3",
"filename" : "Otto the Cat-withMIME.MP3",
"contentType" : "audio/mpeg"
}再通过id去删除试试，结果报错：
➜ 英语资源 mongofiles -d gridfs delete_id ObjectId("5abb6194a4bc71165f9f49f5")
zsh: unknown file attribute: 5mongofiles delete_id unknown file attribute: 5
后来试了，加上引号即可：
➜ 英语资源 mongofiles -d gridfs delete_id 'ObjectId("5abb6194a4bc71165f9f49f5")'
2018-03-29T10:31:02.611+0800 connected to: localhost
successfully deleted file with _id ObjectId("5abb6194a4bc71165f9f49f5") from GridFS效果，果然删掉了：

"chunkSize" : 261120,
