I try to simply pass two parameters to a powershell function. The seccond parameter $args keeps being empty in the function. What am I missing?
$t= "wi-fi Adapter"
if (multilike $t "*wi-fi*,*wireless*,*wan miniport*" ) {
Write-Host "True"
}
function multilike($text, $args) {
foreach ($arg in $args.split) {
if ($text -like $arg) {return $true}
}
return $false
}
Two things:
$args$args is an automatic variable, using it as a declared parameter might result in unexpected behavior
Split()$someString.Split is going to emit the method signatures of the String.Split() method overloads - in order to actuall execute the method, you need to supply a(n empty) parameter list:
function multilike($text, $patterns) {
foreach($pattern in $patterns.Split())
{ # ...
Since you want to accept one-or-more strings as your second parameter argument, you might benefit from declaring it an array of strings:
function multilike {
param(
[string]$text,
[string[]]$patterns
)
foreach($pattern in $patterns) # no need to .Split() any longer
{ # ...
And then call like:
multilike $t *wi-fi*,*wireless*,"*wan miniport*"
$args.split->$args.split(), although you might want to use a variable name other thanargs
