NAME
fmt - simple text formatters
SYNOPSIS
fmt [
-cs] [
-w width |
-width] [
inputfile]...
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 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:
!}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 |
-width Fill output lines to up to
width columns.
OPERANDS
inputfile Input file.
ENVIRONMENT VARIABLES
