In the Modules folder you'll find my modules.

Contains some handy cmdLets that I think should be included by default.

• Get-Size : itterate through a directory and return the total size (in bytes).
• Convert-Size : converts a size from one unit to another. E.g. x KiB (kibibytes) -> y MB (megabytes)
• Get-SizeConverted : Combination of the 2 above. Supports the -ShowOnlyRelevant switch, to automatically pick the most meaningful unit for that specific size.
• Update-File : the PowerShell equivalent of the unix touch command.
• Suspend-Computer and Hibernate-Computer : suspend / hibernate the local machine.
• Get-ConfirmImpact : displays the value of the ConfirmImpact property of the cmdLet binding metadata attribute.
• Get-MyPublicIP : Returns your publicly visible ip address.

See the cmdLet specific Get-Help pages for detailed info. (or the unit tests as well)
