Set-ProgrammerAlias.ps1


  1. <# 
  2. .SYNOPSIS 
  3.     This script creates a function to set aliases for all Cmdlets which omit the '-' 
  4. .DESCRIPTION 
  5.     This script defines a function which uses Get-Command to find all
  6.     cmdlets. For each of them, it then creates an alias which omits
  7.     the "-". This function  was oritinally written by Jeffrey Snover for
  8.     Monad back in the day, but I updated it slightly for PowerShell V2. 
  9.     Updated after a comment to be a tad shorter.
