Display all service names matching a string pattern

I'm trying to display the name (just the name) of all of the installed services that contain the string "SQL". For example, I want to see

• SQLAgent$SQL2008_R2
• SQLBrowser
• SQLWriter

So I try this:

Get-WmiObject Win32_Service

This displays all of the services, but as a list.

Exit Code : 0
Name      : ProtectedStorage
ProcessId : 664
StartMode : Manual
State     : Running
Status    : OK

Exit Code : 1077
Name      : QWAVE
ProcessId : 0
StartMode : Manual
State     : Stopped
Status    : OK
(etc...)

This is good, but I just want to see the name. So I type:

Get-WmiObject Win32_Service | select-object Name

And I get what I expect:

sppuino开发者_运维问答tfy
SQLAgent$SQL2008_RT
SQLBrowser
SQLWriter
SSDPSRV
(etc ..)

All is good. I take the next step of filtering the names to only include SQL related ones:

Get-WmiObject Win32_Service | select-object Name | select-string -pattern 'SQL'

And now it's confusing. Here is my output:

@{Name=BcmSqlStartupSvc}
@{Name=MSOLAP$SQL2008_R2}
@{Name=MSSQL$SQL2008_R2}
(etc ...)

Why am I getting this output, instead of just the names? What should I be typing to get just the names?

You can use Get-Service instead of get-WMIObject and do it like this"

get-service sql* | select -expand name

The easiest way to achieve that is using -Filter Parameter

Get-WMIObject Win32_Service -Filter "Name LIKE '%SQL%'" | 
Select -ExpandProperty Name

In case, you want to go with your code only, here is the way you can modify it:

Get-WmiObject Win32_Service | Select-Object -ExpandProperty Name | 
Select-String -pattern 'SQL'

Edit: LIKE operator takes a few meta characters to support matching pattern.

[] - for range matching. For example, Name LIKE '[a-f]%' will list all services starting with any letter from a to f.

^ - not. For example, Name LIKE '[^a-f]%' will list services that do not start with any letter from a to f.

_ - matches one letter. For example, Name LIKE 'S_L%' will list services that start with S and followed by any letter.

Get-Service | Where-Object {$_.Name -match "SQL"} |Select-Object Name
