PowerShell vs Bash – What’s the Difference?

If you have been following IT trends for any length, you will no doubt have seen a few Windows Vs. Linux articles. But comparing these OSes against each other is not always fair or logical. It is usually an apples-to-oranges comparison based on the tasks being measured.
Both Windows and Linux are very capable operating systems. Each has its own pros and cons, which we can debate. How often do you think about the scripting and automation capabilities of these OSes? We decided to take a look at some of what you can do with the scripting capabilities that come with Linux and Windows.
PowerShell: A Little History
Windows was not the best at automating tasks. This was partly due to the way it implemented its command line. It was a throwback very much to the DOS prompt that made Microsoft the huge success it is today. It was lacking features compared to Unix or later Linux systems.
PowerShell, Microsoft’s automation framework and task framework, is useful for configuration management. PowerShell uses components called cmdlets, which are built into PowerShell. Modules provide additional functionality. These modules can be installed directly from the command line via the PowerShell Gallery.

Start trainingPowerShell differs from Bash because it can interact with.NET structures natively within Windows. It can also pipe objects and data between sessions, scripts, and applications. Each object has its own set of properties which makes data handling in PowerShell even more precise. Data can be specified in numbers (integers), words, strings, Boolean (true or false), and many other formats. This allows you to be very specific in how your scripts handle data input and output.
Bash: A Little History
Unix and Linux systems have always benefitted from being structured in a multi-user terminal environment. This allows you to launch additional sessions on the system and run scripts or applications without affecting the main session that other users are currently logged in to. This is a significant change from the early Windows and DOS systems, which were single-user environments with single sessions until Windows NT was introduced in the mid 90s.
The original Unix shell was the Bourne Shell, named after Stephen Bourne. Bash (Bourne Again Shell) is an open-source successor to the Bourne Shell. Bash was widely used when Linux was first created in the early 1990s. This is why it is still in widespread use today.
Bash’s most popular features include system stability and open source. Because of this, it is available in almost every Linux distribution. These factors make it an IT professional’s most preferred scripting environment.
When to use PowerShell
Since PowerShell development was made a part of the Microsoft landscapes, Windows administration has been much easier. Sysadmins no longer have to deal with cumbersome batch files or the Windows Scheduler. Instead, they can access a new toolbox full of useful apps and functions.
PowerShell can go into the finer details to create powerful scripts. PowerShell can pull data directly from the WMI subsystem. This allows you to get real-time, detailed information about any process IDs or Handle counts.
PowerShell can be plugged into the.NET Framework, so you can create beautiful menus and winforms that look just like real applications. PowerShell can be used to query SQL Databases and to grab your favorite RSS Feeds into your PowerShell session for further manipulation. It is a great tool for system administration in Windows environments.
