Question

Like in C and other languages, you can give to the script/.exe arguments when you physically execute the script. For example:

myScript.exe Hello 10 P

Whereby Hello, 10 and P are passed to some variable in the program itself.

Is this possible in Powershell? and if so, how do you give those args to a given $variable

Thanks!

Answer 1

Define your script with a param block like so:

-- Start of script foo.ps1 --
param($msg, $num, $char)

"You passed in $msg, $num and $char"

You can further type qualify parameters as well e.g:

-- Start of script foo2.ps1 --
param([string]$msg, [int]$num, [char]$char)

"You passed in $msg, $num and $char"

You can also specify default values and required values e.g.:

-- Start of script foo3.ps1 --
param([string]$msg=$(throw "Msg param is required"), [int]$num, [char]$char="P")

"You passed in $msg, $num and $char"

You can get even fancier with advanced functions (specify attributes to validate parameters, etc). But this should get you going.
