How to execute mongo commands from bash?

Question

I am trying to run this command from bash script:

 mongo 192.168.10.20:27000 --eval \"use admin && db.shutdownServer() && quit()\"

Answer 1

You can use heredoc syntax.

#! /bin/sh
mongo <

Turns out heredoc syntax throws a warning when EOF is missing at the end for bash script. This is the bash script version.

#! /bin/bash
mongo <

Here is the output, I guess this is what you expected.

MongoDB shell version: 2.4.14
connecting to: test
switched to db admin
