[Batch] Scan a .txt file for a string

[liambiscuit]

I would like to scan a file, "banned.txt", for a specific string, ex, "Liam". How do I do this, as I am pretty sure there is a command?

Liam

EDIT: Also, how do i delete this text. I remember a command in VB.NET that i used, Replace(
file,
query,
replacewith)

what have you tried? i will give you a hint. use findstr on the commandline if your requirement is that simple.

"findstr /?" in cmd.exe seems like plenty, will post again if more help is needed.
