Both Power Shell and Bash Shell provide one intelligent command line interface (CLI) by using their configuration management tool. Note that power shell is similar to bash most commands used in bash can be used in power shell such as 'rm','ls', and 'cp'.Both the shell include commands for managing files navigating directories and launching other programs. So what is the major difference between the power shell and bash shell, so note that the power shell is a command shell and associated scripting language for the majority of windows operating systems. while bash is a command shell and associated scripting language for the Linux operating system. power shell was introduced in 2006 with its first version while the bash shell is much older and was introduced in 1989 and also user interface of the bash shell is a text-based command line interface while that of the power shell is a graphical command line interface CLI. Also, note that in the power shell it treated input and output as an object while in the bash shell it accepts input and output as text structure. Power shell can be executed on any version of windows from windows 10 to windows 97 while bash shell was majority prepared for the Linux operating system from the first day.

So this is the major difference between the power shell and the bash shell. So let's go back to the history of PowerShell back then Microsoft windows was not considered good at task automation compared to Linux. It was because of the limited funtalinity of the command prompt, so in 2002 Microsoft started working on it and in 2006 it was launched.
