A pipe is a form of redirection in Linux used to connect the STDOUT of one command into the STDIN of a second command. It allows us to narrow the output of a string of commands until we have an easily digestible amount of data. The pipe character is the | symbol and is placed between any two commands. Pipes are one of the most used command-line features that Linux has. Every article showing Linux commands will almost inevitably include pipes. 

One of the most popular command-line utilities is the find command, mainly because of its simplicity and versatility. It's the default option to search for files across multiple UNIX based systems with a wide range of parameters and variables to narrow down our searches. It helps look for files matching a specific name, date, size, or even owner to provide a frame to append other commands to the list of files found. The basic structure of the find command is as follows. 

Knowing your server's IP address(s) can be useful information to have for various reasons. After all, other than your domain, the server's IP is the main address used to reach the server. Knowing a server's IPs may be necessary when making changes to: DNS, networking, and security. A server may have a single IP, or multiple IPs, but sometimes, you may need a quick method to double-check since it's easy to forget.

What is SmartCTL?

Every modern hard drive has an option to monitor its current status and health via SMART attributes. SMART stands for Self-Monitoring, Analysis, and Reporting Technology. The SMART test can be performed on your HDD to detect any potential problems with the hardware itself. Tests such as these are run using SmartCTL. According to the Linux man page, SmartCTL is a command-line utility designed to perform SMART tasks. Examples of these tasks would be printing error logs or enabling and disabling automatic SMART testing. 

What is Bash?

Bash, or the Bourne Again SHell, is based on the Bourne shell. It is the default shell command language interpreter for GNU Linux/Unix and is accessed via a terminal. The shell was the original method for interacting with the operating system before GUIs were implemented. It has the ability to execute single commands, understand regular expressions, as well as scripts written in the bash language. It is currently the default interactive shell on most all modern Linux distributions.

In this article, we will discuss how and why a VPS server or Dedicated server might block an IP address and how to resolve it.
