I'm trying to upload a .json file to my db with mongoimport. i'm using this chain of commands (without the sensitive info):
mongoimport <host uri that starts with: mongodb+srv://...> --authenticationDatabase "admin" --authenticationMechanism= "SCRAM-SHA-1" --collection "..." --file "C:\Users\Jose Miguel\Documents\tinto programa\tinto-programas-3\database\DATA\JSON\2022\JUNIO\JUNIO 2022.json" --username "..." --password "...."
The complete error is the following:
error parsing command line options: error parsing positional arguments: cannot use both --file and a positional argument to set the input file
what could be wrong? i've already read the documentation and everything seems to be in its right place.
EDIT: as per #Joe suggestions, I have edited my command chain to look like this:
mongoimport <connection string, now without quotes> --authenticationMechanism "SCRAM-SHA-1" --authenticationDatabase=admin --collection=<collection_name> --file "C:\Users\Jose Miguel\Documents\tinto programa\tinto-programas-3\database\DATA\JSON\2022\JUNIO\JUNIO 2022.json" --username=<...> --password=<...>
A positional argument is one that is separated from the rest of the command by whitespace, and not introduced with a preceding option that starts with a dash.
Mongoimport can take at most 2 positional arguments: a connection string and a file
Check <host uri that starts with: mongodb+srv://...>, if there are any spaces or shell-reactive characters, escape and/or quote the string
Many of the options to mongoimport can use either = or space to separate the option from its argument, however --authenticationMechanism= "SCRAM-SHA-1" may be interpreted as an empty string for auth mechanism, with "SCRAM-SHA-1" as a positional argument. Use either --authenticationMechanism="SCRAM-SHA-1" or --authenticationMechanism "SCRAM-SHA-1"
I am trying to use the dynamic database name in the below bash script, but it fails with an error saying invalid escape sequence.
#!/bin/bash
...
...
db_name=test
db_existence=$(mongo mongodb+srv://$db_credentials$mongoatlas_host --eval 'db.getMongo().getDBNames().indexOf(\"$db_name\")' --quiet)
I also tried using double quotes with --eval and single quotes for DB name as in the below script, but still, it gives the same invalid escape sequence error.
db_existence=$(mongo mongodb+srv://$db_credentials$mongoatlas_host --eval "db.getMongo().getDBNames().indexOf(\'$db_name\')" --quiet)
It uses the variable name as it is if I don't use \ escape character with db_name.
I can't hardcode the DB name as my database name is coming from another command.
I think that I might be missing something very fundamental in terms of bash scripting.
Please help.
Use one of those:
--eval "db.getMongo().getDBNames().indexOf('$db_name')"
--eval 'db.getMongo().getDBNames().indexOf("'$db_name'")'
--eval "db.getMongo().getDBNames().indexOf(\"$db_name\")"
I have tried running the shell command:
mongoexport -d=local_db -c=ColName -q= '{ "FieldName":{"$ne":"null"}}' --out=NameofJson.json --jsonArray
But I return the error:
too many positional arguments: ['{ FieldName:{$ne:null}}']
What is the correct Syntax?
Get rid of the extra whitespace after -q:
-d=local_db -c=ColName -q='{ "FieldName":{"$ne":"null"}}' --out=NameofJson.json --jsonArray
If you are processing this in Linux please see Buzz Moschetti's answer. In windows the command was:
mongoexport -d=local_db -c=ColName -q="{ 'FieldName':{'$ne':null}}" --out=NameofJson.json --jsonArray
Im trying to do a mongoexport to CSV but only selecting certain records with a query. Here's my command (windows 7 cmd):
mongoexport --host foo.com --port 27017 --username bar -p --db foo --csv --fields col1,col2,col3 --collection bar --out dump_q.csv --query '{"recent":"yes"}'
However after entering the password, I get an error:
assertion: 16619 code FailedToParse: FailedToParse: Expecting '{': offset:0
The command works fine without the query argument but I cant figure out whats wrong with the query:
--query '{"recent":"yes"}'
Any help much appreciated
Summary of answer:
Make sure you use double quotes on enclose the query and single quotes to enclose strings e.g.
--query "{'recent':'yes'}"
Also make sure you don't have a space in your query otherwise the command prompt will parse it as another argument. So don't have:
--query "{'recent': 'yes'}"
(notice the space in-between)
Queries which include nested fields don't work such as:
--query "{'folder.recent':'yes'}"
You'll need to use double quotes to contain the query string (and either single quotes or two quotes to escape inside of the string)
--query "{'recent':'yes'}"
Complete:
mongoexport --host foo.com --port 27017 --username bar -p
--db foo --csv --fields col1,col2,col3
--collection bar --out dump_q.csv --query "{'recent':'yes'}"
From mongoexport documentation:
--query , -q
Provides a JSON document as a query that optionally limits the documents returned in the export.
Your query string seems to be correctly formated. You can even ommit the double quotes around recent.
Single or double quotes don't seem to matter, as long as you are persistent in using different types on the outside and the inside.
Are you sure this is a valid query though? What is the output if you run the following in the database? What about a find()?
db.bar.count({"recent":"yes"})
mongoexport -h db.mysite.com -u myUser -p myPass -c myCollection
But the response I get is:
ERROR: too many positional options
What's that about?
I had this same problem. In my case, I was using mongoexport with the --query option, which expects a JSON document, such as:
mongoexport ... --query {field: 'value'} ...
I needed to surround the document with quotes:
mongoexport ... --query "{field: 'value'}" ...
I had the same problem. Found a group post somewhere which said to remove the space between the '-p' and the password, which worked for me.
Your sample command should be:
mongoexport -h db.mysite.com -u myUser -pmyPass -c myCollection
The same error I have encountered while importing a csv file.
But its just, the fact that the field list which you pass for that csv file import may have blank spaces.
Just clear the blank spaces in field list.
Its the parsing error.
I had the same issue with mongodump. After searching a bit, I found out that using the --out parameter to specify the output directory would solve this issue. The syntax for using the out parameter is
mongoexport --collection collection --out collection.json
Also in case your Mongodb instance isn't running, then you could use the --dbpath to specify the exact path to the files of your instance.

I had the same issue with the mongoexport utility (using 2.0.2). My fix was to use the FULL parameter name (i.e. not -d, instead use --db).
Sometimes editor will screw it up (such as evernote). I fixed the issue by retyping the command in terminal.
I was also stuck in same situation and found what was causing it.
Make sure you are exporting in CSV format by adding parameter --type csv
Make sure there are no spaces in fields name,
Example: --fields _id, desc is wrong but --fields id,desc,price is good
This also works if you place the -c option first. For me, this order does work:
mongoexport -c collection -h ds111111.mlab.com:11111 -u user -p pass -d mydb
You can also leave the pass out and the server will ask you to enter the pass. This only works if the server supports SASL authentication (mlab does not for example).
for the (Error: Too many arguments)
Dont Use Space Between the Fields
try:
mongoexport --host localhost --db local --collection epfo_input --type=csv --out epfo_input.csv --fields cin,name,search_string,EstablishmentID,EstablishmentName,Address,officeName
Dont_Try:
mongoexport --host localhost --db local --collection epfo_input --type=csv --out epfo_input.csv --fields cin,name,search_string,Establishment ID,Establishment Name,Address,office Name
Had a similar issue
$too many positional arguments
$try 'mongorestore --help' for more information
Simply fix for me was to wrap the path location in quotes " "
This Failed:
mongorestore -h MY.mlab.com:MYPORT -d MYDBNAME -u ADMIN -p PASSWORD C:\Here\There\And\Back\Again
This Worked:
mongorestore -h MY.mlab.com:MYPORT -d MYDBNAME -u ADMIN -p PASSWORD "C:\Here\There\And\Back\Again"
I had the same issue with starting mongod. I used the following command:
./mongod --port 27001 --replSet abc -- dbpath /Users/seanfoley/Downloads/mongodb-osx-x86_64-3.4.3/bin/1 --logpath /Users/seanfoley/Downloads/mongodb-osx-x86_64-3.4.3/log.1 --logappend --oplogSize 5 --smallfiles --fork
The following error message appeared:
Error parsing command line: too many positional options have been specified on the command line
What fixed this issue was removing the single space between the '--' and 'dbpath'
I had the same issue while using the "mongod --dbpath" command. What I was doing looked somewhat like this:
mongod --dbpath c:/Users/HP/Desktop/Mongo_Data
where as the command syntax was supposed to be:
mongod --dbpath=c:/Users/HP/Desktop/Mongo_Data
This worked for me. Apart from this one may take a note of the command function and syntaxes using the mongod --help command.
In my case, I had to write the port separately from the server connection. This worked for me:
mongoexport --host=HOST --port=PORT --db=DB --collection=COLLECTION
--out=OUTPUT.json -u USER -p PASS
Create a json file in the same folder where you have your mongod.exe.
eg: coll.json
and open a command prompt in this folder.
type this below in CMD.
mongoexport --db databasename --collection collectionname --out
coll.json
and you will see like a progress bar very cool exporting all data.
