fmt - simple text formatter
fmt [goal [maximum]] [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 out-
put a version of its input with lines as close to the goal length as pos-
sible without exceeding the maximum. The goal length defaults to 65 and
the maximum to 75. The spacing at the beginning of the input lines is
preserved in the output, as are blank lines and interword spacing.
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(1) editor (e.g. vi(1)) the command
will reformat a paragraph, evening the lines.
The fmt command appeared in 3BSD.
The program was designed to be simple and fast - for more complex opera-
tions, the standard text processors are likely to be more appropriate.
