Powershell Delete String in text file

Question

I have a file that I am downloading daily what I want to do is create a script that reads the text file and deletes out any lines containing the string "---"

I started with "(get-content L:\holdings.txt) | where {$_ -ne "" | out-file holdings.txt"

This deletes all the blank lines without any issue, I then tried

$del -like "*-*"
"(get-content L:\holdings.txt) | where {$_ -ne $del | out-file L:\holdings.txt"

Which I though would delete out any of the lines of data, whilst it runs without error the line is not being deleted out...

I don't know if it's relevant but the line I want to delete will always be the second line as it is a comma delimited SQL batch file automation.

The file reads as follows

Advice Num ,Bargain Number
--------------------,-----------------

Just to try and give you a graphical representation that I am trying to resolve

Any ideas?

Solution

Solved it, a quick amendment and here it is (get-content "L:\movement.txt") -notmatch "---" | out-file "L:\movement.txt"
