MongoDB Getting started with MongoDB Making the output of find readable in shell
Example
We add three records to our collection test as:
> db.test.insert({"key":"value1","key2":"Val2","key3":"val3"})
WriteResult({ "nInserted" : 1 })
> db.test.insert({"key":"value2","key2":"Val21","key3":"val31"})
WriteResult({ "nInserted" : 1 })
> db.test.insert({"key":"value3","key2":"Val22","key3":"val33"})
WriteResult({ "nInserted" : 1 })
If we see them via find, they will look very ugly.
> db.test.find()
{ "_id" : ObjectId("5790c5cecae25b3d38c3c7ae"), "key" : "value1", "key2" : "Val2
", "key3" : "val3" }
{ "_id" : ObjectId("5790c5d9cae25b3d38c3c7af"), "key" : "value2", "key2" : "Val2
1", "key3" : "val31" }
{ "_id" : ObjectId("5790c5e9cae25b3d38c3c7b0"), "key" : "value3", "key2" : "Val2
2", "key3" : "val33" }
To work around this and make them readable, use the pretty() function.
> db.test.find().pretty()
{
"_id" : ObjectId("5790c5cecae25b3d38c3c7ae"),
"key" : "value1",
"key2" : "Val2",
"key3" : "val3"
}
{
"_id" : ObjectId("5790c5d9cae25b3d38c3c7af"),
"key" : "value2",
"key2" : "Val21",
"key3" : "val31"
}
{
"_id" : ObjectId("5790c5e9cae25b3d38c3c7b0"),
"key" : "value3",
"key2" : "Val22",
"key3" : "val33"
}
