FMT(1)FMT(1)NAMEfmt - simple text formatters
SYNOPSISfmt [-cs] [-w width | -width] [inputfile]...
DESCRIPTIONfmt 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 stan‐
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 com‐
reformats the text between the cursor location and the end of the para‐
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 para‐
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
-w width | -width
Fill output lines to up to width columns.
See environ(5) for a description of the LC_CTYPE environment variable
that affects the execution of fmt.

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