.SH NAME
|
|
fold \- wrap each input line to fit in specified width
|
|
.SH SYNOPSIS
|
|
.B fold
|
|
[\-bs] [\-w width] [\-\-bytes] [\-\-spaces] [\-\-width=width] [file...]
|
|
.SH DESCRIPTION
|
|
This manual page
|
|
documents the GNU version of
|
|
.BR fold .
|
|
.B fold
|
|
prints the specified files, or the standard input when no files are
|
|
given or the filename `\-' is encountered, on the standard output. It
|
|
breaks long lines into multiple shorter lines by inserting a newline
|
|
at column 80. It counts screen columns, so tab characters usually
|
|
take more than one column, backspace characters decrease the column
|
|
count, and carriage return characters set the column count back to zero.
|
|
.SS OPTIONS
|
|
.TP
|
|
.I "\-b, \-\-bytes"
|
|
Count bytes rather than columns, so that tabs, backspaces, and
|
|
carriage returns are each counted as taking up one column, just like
|
|
other characters.
|
|
.TP
|
|
.I "\-s, \-\-spaces"
|
|
Break at word boundaries. If the line contains any blanks, the line
|
|
is broken after the last blank that falls within the maximum line
|
|
length. If there are no blanks, the line is broken at the maximum
|
|
line length, as usual.
|
|
.TP
|
|
.I "\-w, \-\-width width"
|
|
Use a maximum line length of
|
|
.I width
|
|
columns instead of 80.
|
|
.PP
|
|
The long-named options can be introduced with `+' as well as `\-\-',
|
|
for compatibility with previous releases. Eventually support for `+'
|
|
will be removed, because it is incompatible with the POSIX.2 standard.
