I am new to PowerShell, but not scripting.
Why does this script:
$usr = "john.doe"
$usrname = $usr -split ".", 0, "simplematch"
$fullname = upperInitial($usrname[0]) + upperInitial($usrname[1])
write-host "Hello $fullname"
function upperInitial($upperInitialString) {
return $upperInitialString.substring(0, 1).toupper() + $upperInitialString.substring(1).tolower()
}
return me just 'Hello John' and not 'Hello John Doe'?
It's not treating the second call of the upperInitial function as a function, it's treating it as a paramter of the first call to the function I think.
Either of these work:
$fullname = "$(upperInitial($usrname[0])) $(upperInitial($usrname[1]))"
write-host "Hello $fullname"
The above uses the subexpression operator $() to execute the functions within a double quoted string.
$fullname = (upperInitial($usrname[0])) + ' ' + (upperInitial($usrname[1]))
write-host "Hello $fullname"
This one combines the result of the two functions as you had intended, although I also added a space character because otherwise it was JohnDoe.
FunctionName $Arg1 $Arg2, not FunctionName($Arg1,$Arg2). They work like a cmdlet, not like a C# function. For a single argument function you probably won't have issues, but functions with multiple arguments will not work because parentheses have a different meaning in PowerShell. It's best to avoid looking like the C# syntax completely.
