MongoDB is a popular NoSQL database that provides high-performance and scalable storage solutions. In this blog post, we will explore how to install and work with MongoDB on a Linux system using the Bash command-line interface.

Installing MongoDB

Before getting started, ensure that you have Bash installed on your Linux system. To install MongoDB, follow the steps below:

Open Terminal by pressing Ctrl + Alt + T or searching for “Terminal” in your system’s applications.
Update the package list by running the following command:
```
sudo apt update
```
Install MongoDB by executing the following command:
```
sudo apt install mongodb
```
Once the installation completes, start the MongoDB service using the following command:
```
sudo systemctl start mongodb
```

Congratulations! You have successfully installed MongoDB on your Linux system.

Interacting with MongoDB

MongoDB provides a command-line interface called mongo to interact with the database. To access the MongoDB shell, follow the steps below:

Open Terminal and execute the following command:
```
mongo
```
This will connect you to the local MongoDB instance.
In the MongoDB shell, you can execute various commands to manage databases, collections, and documents. Here are a few essential commands:
- To show all available databases, use:
```
show databases
```
- To switch to a specific database or create a new one, use:
```
use <database_name>
```
- To show all collections in the current database, use:
```
show collections
```
- To perform queries or insert documents into a collection, use the MongoDB query language. For example:
```
db.<collection_name>.find()
db.<collection_name>.insertOne({key: "value"})
```
