FMT(1)
NAME
fmt − simple text formatter
USAGE
fmt [ name ... ]
DESCRIPTION
Fmt is a simple text formatter that reads the concatenation of input files (or standard input) and produces, on standard output, a version of its input with lines as close to 72 characters in length as possible. Spacing at the beginning of the input lines, as well as blank lines and interword spacing, are preserved in the output.
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, the command !}fmt will reformat a paragraph, making the lines even.
The program is designed to be simple and fast. For more complex operations, the standard text processors are probably more appropriate.
