format-table outputting blank? - powershell

Question

What I'm trying to do is look at some processes and get a list of the user of these processes. ANd the following code worked fine for me.
get-wmiobject win32_process |
where{$_.name -like "*notepad*"}|sort {$_.CommandLine}|
select #{n="User";e={$_.getowner().user}},#{n="ProcessID";e={$_.ProcessID}},{$_.CommandLine} |ft -AutoSize |Out-String -Width 300 >> C:\ListUsers.txt
Somehow I wanted to split the $_.CommandLine string in the middle of way, and output some of the split arrary(see the following code for a better idea, although the code is wrong). But the updated code just output nothing into the text file. I think I must be using the select-object or fommat-object wrong, but i don't know how i can fix it.
get-wmiobject win32_process |
where{$_.name -like "*notepad*"}|sort {$_.CommandLine}|
%{
$split = $_.CommandLine.split("\")
select #{n="User";e={$_.getowner().user}},#{n="ProcessID";e={$_.ProcessID}},#{n="Ihub";e=$split[3]},#{n="version";e=$split[3]},#{n="version";e=$split[3]} |
ft -AutoSize |Out-String -Width 300 >> C:\ListUsers.txt
}
Can anyone advise? Thanks!!

You don't need to use select and then format-table. Format-table can create calculated properties too. Also, you forgot to wrap the $split[3] in a scriptblock. I removed the two "version" properties because they were identical to "Ihub".
Try this(untested):
get-wmiobject win32_process |
where{$_.name -like "*notepad*"}|sort {$_.CommandLine} |
Format-Table -Property #{n="User";e={$_.getowner().user}},#{n="ProcessID";e={$_.ProcessID}},#{n="Ihub";e={($_.CommandLine.split("\"))[3]}} -AutoSize |
Out-String -Width 300 >> ListUsers.txt
