Need to quickly see all of the environment variables on your system? Use the `Get-ChildItem` cmdlet with the `Env:` drive to easily list them all with their values.

Alternatively, you can also use the Environment class functions `GetEnvironmentVariables()` and `GetEnvironmentVariable('EnvironmentVariableName')` to get the same information.
'@
$tip.Example = @'
# List all environment variables and their values.
Get-ChildItem Env:

# You can do the same thing using one of the aliases for Get-ChildItem.
gci Env:
dir Env:

# List a specific environment variable. e.g. the PATH environment variable.
Get-ChildItem Env:Path

# Alternatively, you can use the Environment class functions.
[Environment]::GetEnvironmentVariables()
[Environment]::GetEnvironmentVariable('Path')
