MongoDB remove GridFS objects from shell
You can delete gridFS file by deleting both chunks and files from shell. for example
db['fs.chunks'].remove({files_id:my_id});db['fs.files'].remove({_id:my_id});Those commands will do such trick.
You want to use db.fs.delete(_id); instead.
UpdateSorry, that apparently doesn't work from the shell, only through the driver. GridFS is a specification for storage implemented by the drivers. Looks like it doesn't have much built-in functionality from the shell, as such.
Update 2 There is also a command line tool, mongofiles (http://www.mongodb.org/display/DOCS/GridFS+Tools), which allows you to delete files by name. mongofiles delete <filename>. It comes with a warning that it will delete all of the files by that name, so it's not as granular as by id.
