fmt(1) (Directory and File Management) fmt(1)
NAME
fmt - simple text formatters
SYNOPSIS
fmt [ -cs ] [ -w width ] [ file... ]
DESCRIPTION
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 lines beginning with a ``.'' (dot), for
compatibility with nroff(1). Nor does it fill lines starting 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:
!}fmt
reformats the text between the cursor location and the end of the
paragraph.
OPTIONS
-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 Fill output lines to up to width columns.
SEE ALSO
nroff(1), vi(1)
NOTES
The -width option is acceptable for BSD compatibility, but it may go
away in future releases.
