mongo shell --eval does not run

Question

由于某种原因，我无法在mongo中评估此简单字符串，我认为这是因为$exists参数。

mongo database --eval "db.products.find({'csv': {'$exists': false}}, {'original.name': true, 'original.sku': true})"

Answer 1

Your quotes are the wrong way around. Use ' on the wrapping of the statement rather than " . Just the important parts:

--eval 'db.products.find({ "csv": { "$exists": false } })'
