.IX Title "FOLD 1"
.TH FOLD 1 "2001-06-06" "perl v5.20.0" "User Contributed Perl Documentation"
.\" For nroff, turn off justification.  Always turn off hyphenation; it makes
.\" way too many mistakes in technical documents.

.SH "NAME"
fold \- wrap each input line to fit specified width
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
\&\fBfold\fR [\fB\-bs\fR] [\fB\-w\fR \fIwidth\fR] [\fIfile\fR ...]
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fIfold\fR command reads lines from the specified files (or standard
input if none are specified) and writes them to the standard output with
newlines inserted into lines longer than the specified column width.
.PP
The default column width is 80, but this may be overridden using the
\&\fB\-w\fR flag.  For historical reasons, the width may be specified directly,
as in \f(CW\*(C`fold \-72\*(C'\fR, omitting the \fB\-w\fR.
.PP
The \fB\-s\fR flag causes breaks to occur after whitespace rather than in
the middle of a word.  This produces a ragged right edge, but is much
nicer to look at.
.PP
The \fB\-b\fR flag makes the program ignore embedded backspaces, tabs, and
carriage returns when deciding where to split.  This makes it run about
thirty times faster.  You might want to get used to using \fB\-b\fR.
.PP
Current locale settings will be honored in determining what 
is meant by \*(L"whitespace\*(R" and \*(L"word characters\*(R".
.SH "BUGS"
.IX Header "BUGS"
\&\s-1POSIX 1003.2\s0 states that a newline will never be inserted
immediately before or after a backspace or a carriage return,
but this is not checked for.
