fmt - simple text formatter
fmt [ -width ] [ name ... ]
Fmt is a simple text formatter which reads the concatenation of input
files (or standard input if none are given) and produces on standard
output a version of its input with lines as close to width characters
long as possible. The spacing at the beginning of the input lines is
preserved in the output, as are blank lines and interword spacing. The
default width is 72 characters.
Fmt is meant to format mail messages prior to sending, but may also be
useful for other simple tasks. For instance, within visual mode of the
ex editor (e.g. vi) the command
will reformat a paragraph, justifying the lines.
The program was designed to be simple and fast - for more complex
operations, the standard text processors are likely to be more
