1. Use PowerShell to Get-Help
If you need help with a PowerShell cmdlet, you can use the Get-Help cmdlet. For example, if you want to know more about the Get-Process cmdlet, you can use the following command:
Get-Help Get-Process
This will display all the information about the cmdlet, including a description, syntax, and examples.
2. Use Aliases
PowerShell has a lot of cmdlets, and it can be difficult to remember them all. That’s where aliases come in handy. Aliases are alternate names for cmdlets that you can use.
For example, the Get-Process cmdlet can be aliased as gp. So, if you forget the name of the cmdlet, you can just use gp instead. To view all the aliases for a cmdlet, you can use the Get-Alias cmdlet.
3. Use Tab Completion
Tab completion is a feature in PowerShell that allows you to automatically complete commands and parameters. For example, if you want to use the Get-Process cmdlet, you can start typing “get-pro” and then press the Tab key.
4. Commenting lines, condensing two lines into one line by preceding the line with a hashmark
To comment out a line in PowerShell, simply precede it with a hash mark (#). This will tell PowerShell to ignore that particular line.
If you want to condense two lines of PowerShell code into one, you can do so by preceding the second line with a hashmark. This is useful if you want to save space or if you want to make your code more readable.
Here is an example of how this would look:
Line 1: Get-Process
Line 2: # Get-Service
This would execute the Get-Process cmdlet and ignore the Get-Service cmdlet.
5. Listing all files in the current directory and recursively through folders
One of the advantages of Powershell is its ability to run scripts securely on a system. By default, Powershell will not run any scripts unless they are signed by a trusted publisher.
This means that any script you download from the internet or receive from an untrusted source will not be able to run on your system unless you change the execution policy.
You can do this by opening Powershell and running the following command:
Set-ExecutionPolicy RemoteSigned
This will allow scripts that are signed by a trusted publisher to run on your system. Scripts that are not signed will still not be able to run.
If you want to be able to run all scripts, regardless of whether or not they are signed, you can set the execution policy to Unrestricted. However, this is not recommended as it can leave your system vulnerable to malicious scripts.
