coolcommand fold - how to create line breaks at maximum characters or bytes
Description To create line breaks on a line in a file using either the number of characters or bytes: # fold [-bs] [ -w width\| -width] [file] where: -b : count width in bytes rather than column positions. -s : if a segment of a line contains a blank character within the first width column positions (or bytes), break the line after the last such blank character meeting the width constraints. If there is no blank character meeting the requirements, the -s option will have no effect for that output segment of the input line. -w width\|-width : specify the maximum line length, in column positions (or bytes if -b is specified). If width is not a positive decimal number, an error is returned. The default value is 80. Example to put a line break after 80 characters on a line have been reached: # fold -w 80 myfile Example to put a line break after 100 bytes on a line have been reached: # fold -b 100 myfile Description: Fold utily will break the lines to have maximam char (-w option) or bytes (-b option).
Example fold -w 80 myfile
