Delete lines containing specific character in text file

Question

How to delete lines containing a specific character in a text file with PowerShell?

Input file example:

12314+000000 00000000
20 300 1238238948023
A+A+000000 00000000
20 500 1238238948023

Output file example:

20 300 1238238948023
20 500 1238238948023

So it will delete lines containing + or specific characters or words.

Answer 1

The simplest way is to use new file to write data in it:

Get-Content "D:\test.txt" | Where-Object {$_ -notmatch '\+'} | Set-Content "D:\out.txt"

That will give:

20 300 1238238948023
20 500 1238238948023

In out.txt.
