Suppose there is a string named as (ai-somename-someid) and it is stored in say

$x='ai-somename-someid'

Now I want to extract (somename)from the given string and pass it into another variable by using split(I am using the below script)

$y = $x.split("-")   
$y 

It is giving me the output as

ai  
somename   
someid  

but I would like to have only

somename

  

as the output.

You can directly pass y[1] as a variable name for someone.

$x= "ai-somename-someid"
$y =  $x.split("-")
$y[1]

There's a couple of way you can do that : If you only want one item this is the most straight forward way to do it. Simply cut your string and reference the id of the element you want to save.

$x="ai-somename-someid"
$y=$x.split("-")[1]

or you could do this instead if you are interested in keeping the other parts :

$x="ai-somename-someid"
$z,$y,$v=$x.split("-")

In this exemple $z will have ai, $y somename and $v someid.

If you are only interested in keeping some of the resulting string you can do this :

$x="ai-somename-someid"
$z,$y,$null=$x.split("-")

In this exemple $z will have ai, $y somename and everything after that goes to the trash.

Or using the split operator. This is really about picking the 2nd element of an array. The count starts at 0.

'ai-somename-someid' -split '-' | select-object -index 1
somename

-split on the left side will split on whitespace.

(-split 'ai somename  someid')[1]
somename
