I'm pretty new when it comes to scripting with powershell (or in general whe it comes to scripting). The problem that i have, is that i got a bunch of variables i want to output in one line. Here is not the original but simplified code:
$a = 1
$b = 2
$c = $a; $b;
Write-output $c
The output looks like this:
1
2
You may guess how i want the output to look like:
12
I've searched the net to get a solution but nothing seem to work. What am i doing wrong?
Right now you're only assigning $a to $c and then outputting $b separately - use the @() array subexpression operator to create $c instead:
$c = @($a; $b)
Then, use the -join operator to concatenate the two values into a single string:
$c -join ''
You can make things easier on yourself using member access or Select-Object to retrieve property values. Once the values are retrieved, you can them manipulate them.
It is not completely clear what you really need, but the following is a blueprint of how to get the desired system data from your code.
# Get Serial Number
$serial = Get-CimInstance CIM_BIOSElement | Select-Object -Expand SerialNumber
# Serial Without Last Digit
$serialMinusLast = $serial -replace '.$'
# First 7 characters of Serial Number
# Only works when serial is 7 or more characters
$serial.Substring(0,7)
# Always works
$serial -replace '(?<=^.{7}).*$'
# Get Model
$model = Get-CimInstance Win32_ComputerSystem | Select-Object -Expand Model
# Get First Character and Last 4 Characters of Model
$modelSubString = $model -replace '^(.).*(.{4})$','$1$2'
# Output <model substring - serial number substring>
"{0}-{1}" -f $modelSubString,$serialMinusLast
# Output <model - serial number>
"{0}-{1}" -f $model,$serial
Using the syntax $object | Select-Object -Expand Property will retrieve the value of Property only due to the use of -Expand or -ExpandProperty. You could opt to use member access, which uses the syntax $object.Property, to achieve the same result.
If you have an array of elements, you can use the -join operator to create a single string of those array elements.
$array = 1,2,3,'go'
# single string
$array -join ''
The string format operator -f can be used to join components into a single string. It allows you to easily add extra characters between the substrings.
"$a$b", the semi colon in Powershell means statement termination. So, since$cis a reference to$a, it prints out 1 due to the semicolon sperating the two variables of$aand$b. So, you're basically saying, print$a, then print$b.
