OK I need to parse a rather large logfile and delete specific lines.
The file is called logfile and is simply a large text file.

Is there some simple way to read in the file and delete specific lines
that contain DSL:[EMAIL PROTECTED] and the rerun the process to delete
[EMAIL PROTECTED] -or-
Delete all lines that contain: "DSL:" and the text :No such user"
