occasionally i see the @ character used in scripts but i'm unsure what it is used for.  could anyone explain this please.

 

Thanks

Lee

These are all the examples I can think of quickly:

PS>$my_array=@() <--an array
PS>$my_hashtable=@{} <--a hashtable
PS>$my_here_string=@" <--a HERE string
>> some_text
>> "@
>>
PS>

So, "@" can be used in various constructs.

Thanks Marco. That helps. I'll have play around and get my head around it properly.

Cheers

Marco - I did not get this? So what is @ is it an alias for a cmdlet, what is it called and what does it do?
Thanks

In version 1, it is _part_ of two operators, the array operator and the hashtable operator.

array: @()
hashtable: @{}

In version 2, there will be an additional meaning which I won't go into here because it won't clarify anything. :)

Maybe construct is a better word than operator.

tease...

 

here ya go, its called splatting.

That is cool, but isn't that still a hashtable?  It seams to me the only real difference is that powershell will unwrap the name value pairs and pass them to the cmdlet.  The construct doesn't appear to be taking a new form.

Thanks

Precisely. I anticipate using this a lot, too.
