fmt - simple text formatters
fmt [-cs] [-w width | -width] [inputfile...]
fmt is a simple text formatter that fills and joins lines
to produce output lines of (up to) the number of characters
specified in the -w width option. The default width is 72.
fmt concatenates the inputfiles listed as arguments. If none
are given, fmt formats text from the standard input.
Blank lines are preserved in the output, as is the spacing
between words. fmt does not fill nor split lines beginning
with a `.' (dot), for compatibility with
nroff(1). Nor does it fill or split a set of contiguous
non-blank lines which is determined to be a mail header, the
first line of which must begin with "From".
Indentation is preserved in the output, and input lines with
differing indentation are not joined (unless -c is used).
fmt can also be used as an in-line text filter for vi(1).
The vi command:
reformats the text between the cursor location and the end
of the paragraph.
-c Crown margin mode. Preserve the indentation of the
first two lines within a paragraph, and align the left
margin of each subsequent line with that of the second
line. This is useful for tagged paragraphs.
-s Split lines only. Do not join short lines to form
longer ones. This prevents sample lines of code, and
other such formatted text, from being unduly combined.
-w width | -width
Fill output lines to up to width columns.

variable that affects the execution of fmt.

The -width option is acceptable for BSD compatibility, but
it may go away in future releases.
