Today, I came across a weird behavior by PowerShell that it doesn’t validate the parameter names 🙁
Below is the sample code that explains the behavior i am speaking about:
PS C:> type .Test-Commandline-Parameters.ps1
param([switch]$Debug)
Write-Host $Debug
PS C:> .Test-Commandline-Parameters.ps1 -debug
True
PS C:> .Test-Commandline-Parameters.ps1 -debugging
False
PS C:> .Test-Commandline-Parameters.ps1 -debu
True
PS C:> .Test-Commandline-Parameters.ps1 -de
True
PS C:> .Test-Commandline-Parameters.ps1 -d
True
PS C:> .Test-Commandline-Parameters.ps1 -debeg
False
PS C:> .Test-Commandline-Parameters.ps1 -deer
False
PS C:>
