Missing ')' in function parameter list.

Question

I can run this script fine:

param (
  [switch]$push = $false
)

Why does running this script:

param (
  [switch]$push = $false
  [string]$string
)

yield this error:

Missing ')' in function parameter list.

?

Answer 1

The error message "Missing ')' in function parameter list" is caused by the fact that the second parameter in the script is missing a comma to separate it from the first parameter. In PowerShell, parameters in a function or script must be separated by commas. To fix the error, add a comma after the first parameter like this:

param (
  [switch]$push = $false,
  [string]$string
)

This will allow the script to run without error and accept two parameters, a switch parameter named "push" with a default value of $false, and a string parameter named "string".
