Overview GNU Spell is a spell checking program which prints each misspelled word on a line of its own. It is designed as a clone of the standard Unix spell program, and implemented as a wrapper for Ispell. Spell accepts as its arguments a list of files to read from. In addition, when called with no file name arguments, Spell assumes that it should process standard input. Spell is most useful when used in conjunction with other programs, because its output is minimalistic.
Human users are usually more comfortable with verbose output.
