Powershell Delete String in text file -

i have file downloading daily want create script reads text file , deletes out lines containing string "---"

i started "(get-content l:\holdings.txt) | {$_ -ne "" | out-file holdings.txt"

this deletes blank lines without issue, tried

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

which though delete out of lines of data, whilst runs without error line not being deleted out...

i don't know if it's relevant line want delete second line comma delimited sql batch file automation.
