Editing long text file
Good morning all, I have a machine running IRIX and I need to edit a text file on the terminal that is literally thousands of lines. Does anyone know the most efficient way to edit portions of files like these? Obviously simply using the vi command isn't going to work since I get a too many lines error. Thanks a lot, James

Dear Guru's
I'm using Putty and want to edit a file. I know we generally use vi editor to do it. As I'm not good in using vi editor, I want to convert the vi into something like text pad. Is there any option in Putty to do the same ? Thanks for your response.
