I am curious how to produce a distinct file list based on this example.
** This example produces a list of all .ps1 and .psm1 files that contain the text "folders", but without the text ".invoke" on the same line.
$text='folders'
dir C:\Workspace\mydirectorytosearch1\ -recurse -filter '*.ps*1' | Get-ChildItem | select-string -pattern $text | where {$_ -NotLike '*.invoke(*'}
dir C:\Workspace\mydirectorytosearch2\ -recurse -filter '*.ps*1' | Get-ChildItem | select-string -pattern $text | where {$_ -NotLike '*.invoke(*'}
This is cool and works well but I get duplicate file output (same file but different line numbers).
How can I keep my file output distinct?

You can use Select-String similar to grep in UNIX or findstr.exe in Windows. Select-String is based on lines of text. By default, Select-String finds the first match in each line and, for each match, it displays the file name, line number, and all text in the line containing the match.
Use Select-String Cmdlet in Windows PowerShell If we want to search for multiple patterns, we can separate the parameter values with a comma under the Pattern parameter.
When you need to search through a string or log files in Linux we can use the grep command. For PowerShell, we can use the grep equivalent Select-String . We can get pretty much the same results with this powerful cmdlet. Select-String uses just like grep regular expression to find text patterns in files and strings.
You can eliminate duplicates wit Select-String and the Unique parameter:
$text='folders'
Get-ChildItem C:\Workspace\mydirectorytosearch1\,C:\Workspace\mydirectorytosearch2\ -Recurse -Filter '*.ps*1' |
Select-String -Pattern $text | Where-Object {$_ -NotLike '*.invoke(*'} |
Select-Object Path -Unique
