Docker containers are great for many reasons, but one of the biggest advantages is that they can be stopped and started at any time. This means that you can easily remove a container if it’s no longer needed or you want to upgrade or reconfigure your system.

So when it comes time to clean up after using Docker, it’s important to remove all of the containers first before starting the process of removing Docker…

HDFS is the Hadoop Distributed File System. It’s a distributed storage system for large data sets which supports fault tolerance, high throughput, and scalability. It works by dividing data into blocks that are replicated across multiple machines in a cluster. The blocks can be written to or read from in parallel, facilitating high throughput and fault tolerance. HDFS provides RAID-like redundancy with automatic failover. HDFS also supports compression, replication, and encryption. The most common use case for HDFS is storing large collections of data such as image and video files, logs, sensor data, and so on. Creating Directory Structure with…

A number is a combination of 0-9 digits—the Bash variables stores all value in the form of strings. Even if the stored value is in string format, we can perform all the arithmetical operations if the stored value is a valid number. As a best practice, we should verify the values of variables before performing the arithmetic operations. A number can be an integer number, a floating point number, or a positive/negative number that prefixes with a “+ and -” symbol. In this tutorial, we have discussed a few methods to verify that the variable contains only digits, integers, and…
