"Unable to find specified file" - Powershell - windows

Question

I wrote this function in my powershell profile:
function start {
if ($args[0] == "blender") {
Invoke-Item 'C:\Program Files\Blender Foundation\Blender 2.90\blender.exe'
}
}
It gives me the error below on line 1, at character 1:
Unable to find specified file
The file path is correct, since if I copy and paste the code Invoke-Item ... in my powershell it opens Blender normally. What can the problem be?
Thank you!

Answer 1

This happens, as your function name collides with Start-Process.:
get-alias -Name start
CommandType Name Version Source
----------- ---- ------- ------
Alias start -> Start-Process
Renaming the function is the first step for correction like so,
function start-myApps {
if ($args[0] == "MyApplication") {
Invoke-Item 'C:\Program Files\MyApplication\MyApplication.exe'
}
}
But that isn't enough, as it gives another an error:
Start-MyApps "MyApplication"
= : The term '=' is not recognized as the name of a cmdlet, function, script file, or operable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
At line:2 char:19
+ if ($args[0] == "MyApplication") {
+ ~
+ CategoryInfo : ObjectNotFound: (=:String) [], ParentContainsErrorRecordException
+ FullyQualifiedErrorId : CommandNotFoundException
This one is caused because Powershell's equality comparison operator is -eq, not ==.
The working version has different name and operator like so,
function start-myApps {
if ($args[0] -eq "MyApplication") {
Invoke-Item 'C:\Program Files\MyApplication\MyApplication.exe'
}
}
