fold

break lines into shorter lines 

Command

SYNOPSIS

fold [-bs] [-w width] [-width] [file...]

DESCRIPTION

fold reads the standard input, or each file, if you specify any. Each input line is broken into lines no longer than width column positions. If you do not specify width on the command line, the default line length is 80. The output is sent to the standard output.

Options

-b 

specifies the width in bytes rather than in column positions; that is, fold does not interpret tab, backspace, and carriage return characters.

-s 

breaks each line after the last blank within width column positions. If there is no blank that meets the requirement, fold breaks the line normally.

-w width 

specifies a maximum line length of width column positions.

-width 

is identical in effect to -w width.

DIAGNOSTICS

Possible exit status values are:

0 

Successful completion.

1 

Failure due to one of the following:

— cannot open the input file
2 

Invalid command line option or a missing width argument.
