PowerShell is an interactive Command-Line Interface (CLI) and automation engine designed by Microsoft to help design system configurations and automate administrative tasks
- Get-Help : use this command to get help with any other command. E.g. to know how the Get-Process command works, type: Get-Help -Name Get-Process
- To get help using wildcard – Get-Help – Name Get-*
- Set-Execution-Policy: Microsoft has by default disabled scripting by default in an effort to prevent malicious code from executing in a PowerShell environment. So Set-Execution-Policy command to control the level of security surrounding PowerShell scripts. 4 levels of security are possible
- Restricted – restricted is the default execution policy and locks PowerShell down so that commands can be entered only interactively. PowerShell commands are not allowed to run
- All Signed – Here the scripts will be allowed to run, but only if they are signed by a trusted publisher
- Remote Signed – Here any locally created scripts and the remote ones only if they are signed by a trusted partner
- Unrestricted – no restrictions and all scripts can run.
- Get-Execution-Policy : get the current execution policy
- Get-Service: provides a list of all the services that are installed on the system. For a specific service, append the – Name switch and the name of the service (can use wildcards)
- ConvertTo-HTML : create a report to send to someone
- Export-CSV: Export data from PowerShell into a CSV file to open with Excel
- Select-Object: Allows to specify specific properties for inclusion. E.g. create a CSV file and use the command – Select-Object with Name to select certain properties
- GET-EventLog:
- Get-Process: similar to Get-Service command
- Stop-Process: to stop a particular process
more to come – executing PowerShell commands through Ansible.
