问题 This question already has answers here : How can I delete a newline if it is the last character in a file? (22 answers) Closed last year . I'm using sed to modify the first part of a text file.

There are a lot of them and some are touchy (well, not that much but all my users don't talk computer fluently :-) ), so I'm looking for a kind of batch (an .exe, a .bat, a .reg possibly if these parameters can only be set in the Register DB, the best being a .NET app) to set them via a single double-click before the deployment.
