Text UI or interactive, not command line. With a command line program you enter the program name, some options and some arguments at the shell prompt and hit enter. The program runs, sends its output (if any) to the standard output and its error message (if any) to the standard error. The shell prompt then returns. Grep is a command line program. -- John Hasler jhas...@newsguy.com Elmwood, WI USA
