Remove lines from a text file if it contains a string

I am trying to remove all the lines from a text file that contains a partial string using the below PowerShell code:

 Get-Content C:\new\temp_*.txt | Select-String -pattern "H|159" -notmatch | Out-File C:\new\newfile.txt

The actual string is H|159|28-05-2005|508|xxx, it repeats in the file multiple times, and I am trying to match only the first part as specified above. Is that correct? Currently I am getting empty as output.

Why is this failing and how can I resolve it?

Solution

  • Escape the | character using a backtick

    get-content c:\new\temp_*.txt | select-string -pattern 'H`|159' -notmatch | Out-File c:\new\newfile.txt
