powershell general usage

• you need to provide path for the ps script for it to work; dot-source it even if in the current directory: .\test.ps1
• NOT case-sensitive; nothing is including variable names defined by you
• Variable
  • prefix name with ‘$’ symbol
  • $v = “hello” and use it as $v everywhere
  • not when you use Set-Variable
  • no need to specify type; if required [int]$number = 1
• functions have to be defined before you can use them, literally the order in the ps file
• End of line is end of command; multi-line use backtick ` to indicate the command continues on next line (no space after backtick)
• Semi-colon ; can be used to separate multiple commands on the same line
• Comment character #; multi-line comments <# ……. #>
• [] brackets can be used to specify the object. [String] represents the string object
