Top Forums UNIX for Beginners Questions & Answers Spliting a line after 255 characters. Post 302996734 by Corona688 on Monday 1st of May 2017 02:19:29 PM

If none of the columns are text strings, you may be able to use the fold command to split upon spaces:
Code:
fold -w 255 -s < inputfile > outputfile

to avoid splitting in an awkward place.

FOLD(1) 						    BSD General Commands Manual 						   FOLD(1)

NAME
fold -- fold long lines for finite width output device SYNOPSIS
fold [-bs] [-w width] [file ...] DESCRIPTION
fold is a filter which folds the contents of the specified files, or the standard input if no files are specified, breaking the lines to have a maximum of 80 characters. The options are as follows: -b Count width in bytes rather than column positions. -s Fold line after the last blank character within the first width column positions (or bytes). -w width Specifies width to use as a line width, instead of the default 80 characters. ENVIRONMENT
LC_CTYPE EXIT STATUS
The fold utility exits 0 on success, and >0 if an error occurs. SEE ALSO
expand(1), fmt(1) STANDARDS
The fold utility conforms to IEEE Std 1003.1-2008 (``POSIX.1''). BUGS
If underlining is present it may be messed up by folding. Width should be a multiple of 8 if tabs are present, or the tabs should be expanded using expand(1) before using fold. BSD
