File Extension Of Powershell Script
Long description – A script is a plain text file that contains one or more PowerShell commands. PowerShell scripts have a,ps1 file extension. Running a script is a lot like running a cmdlet. You type the path and file name of the script and use parameters to submit data and set options.

You can run scripts on your computer or in a remote session on a different computer. Writing a script saves a command for later use and makes it easy to share with others. Most importantly, it lets you run the commands simply by typing the script path and the filename. Scripts can be as simple as a single command in a file or as extensive as a complex program.

Scripts have additional features, such as the #Requires special comment, the use of parameters, support for data sections, and digital signing for security. You can also write Help topics for scripts and for any functions in the script.
