Powershell replace spaces and special characters with hyphen

Question

I want to replace any special characters and spaces in a string with hyphen. Below is my code:

$c = 'This_is my code !@# characters are not $ allowed% remove spaces ^&*(){}[]/_:;,.?/"'''
$c = $c -replace [regex]::Escape('!@#$%^&*(){}[]/:;,.?/"'),('-')
Write-Host $c

Is there any direct way to find all special characters, spaces and replace with a single character hyphen

Answer 1

\W will replace any non word character. it will not replace a-z, A-Z, 0-9

$c = 'This_is my code !@# characters are not $ allowed% remove spaces ^&*(){}[]/_:;,.?/"'''
$c -replace '\W','-'
