I\'m using powershell to \"grep\" my source code for a particular string. If the string is in the file, I would like the name of the file, not the line of code that contains th
I don't think I completely understand what you're trying to do. If you want the output grouped by file, you can pipe into Format-Table with the -GroupBy parameter:
gci . -include "*.sql" -recurse `
    | select-string -pattern 'someInterestingString' `
    | Format-Table -GroupBy Path
If you want to get only the names of the files that match without any other info, you can use Select-Object with the -Unique parameter:
gci . -include "*.sql" -recurse `
    | select-string -pattern 'someInterestingString' `
    | Select-Object -Unique Path
If you're interested in only the file name, regardless whether the name itself appears multiple times in your hierarchy, then you can select the Filename property instead.
Note: The Get-Member cmdlet is a great help in figuring out what properties exist on an object:
gci . -include "*.sql" -recurse `
    | select-string -pattern 'someInterestingString' `
    | Get-Member
You can also use its alias gm instead.
When I'm doing this I just use the -List parameter - yes it does display the line of code but you only get one line per file (no matter how many matches there are):
PS> Get-ChildItem . -r *.cs | Select-String XmlNode -list

If you want the path:
PS> Get-ChildItem . -r *.cs | Select-String XmlNode -list | 
    Format-Table Path
Path
--------
C:\Users\Keith\Pscx\Src\PscxSnapin\Commands\SnapinHelp\CmdletInfo.cs
C:\Users\Keith\Pscx\Src\PscxSnapin\Commands\SnapinHelp\GetSnapinHelpCommand.cs
C:\Users\Keith\Pscx\Src\PscxSnapin\Commands\SnapinHelp\ParameterInfo.cs
C:\Users\Keith\Pscx\Src\PscxSnapin\Commands\Xml\XmlCommandBase.cs
Or if you really only want the filename:
PS> Get-ChildItem . -r *.cs | Select-String XmlNode -list | 
    Format-Table Filename
Filename
--------
CmdletInfo.cs
GetSnapinHelpCommand.cs
ParameterInfo.cs
XmlCommandBase.cs
I found it easier to do
(...|select-string "search").Path
