I get errors running the powershell unless I use a ./ Why???

Thanks.

Thanks in advance.

You probably already figured this out, but the reason why your test script gives seemingly unusual results is that your input is an array. I.e., the comma is actually an operator which means “this is an array” so when you provide input as “one”, “two” you provided an array. Since PS is dynamically typed, your first parameter $a got an array, not a scalar.

Similarly, this explains why Jeff’s script worked – he provided 2 scalars since there was no comma separating the input.

The lesson? Don’t use commas on the command line unless you mean to provide an array.

PS > $a=”one”, “two”
PS > $a
one
two
PS > $a[0]
one
PS > $a[1]
two

I don’t know why, but powershell seems to dislike the () and , seperators.

$DateToCompare = (get-date).AddDays(-1)
$logFiles = get-childitem C:\logs -recurse | ? {$_.LastWriteTime -lt $DateToCompare}
foreach ($f in $logfiles){
Write-Host $f.name
}

I can send the results via email, however, I need the name and lastwritetime of each file on a new line in the variable sent to the email function. In vb it would be something like:

foreach f in fld.files
fileformat = fileformat & vbcrlf
next
SendMail fileformat

Anyone know how this is done in PS? Cheers J

#—
function Test($a, $b) {Write-Host “a=$a, b=$b”}
Test(“one”, “two”)
#—

I would have expected the above to display “a=one, b=two”, but instead it displays “a=one two, b=”. Why is this? How would I pass two strings to a function and get the results I expected?

Caller.ps1 code -
.{.\test.ps1}

Calling a Function that lives outside the main script.
Test.ps1 code -
function Hello {Write-Host “Hello Nitin”}

Caller.ps1 code -
. .\test.ps1
Hello

Make sure you understand when you are attempting to call a script or a function within a script that live outside the main script. This tutorial talks about calling functions but you have to follow “click here to find out how” link under Example 2. Calling a Function from another script file.

Then, I wrote caller.ps1 which contains following line -
.{‘.\test.ps1′}

Both the scripts are in the same folder. When I run caller.ps1 file, it does not show “Hello World” on screen.

Please tell me where I was wrong.
