Full Discussion: Using sed to split hex string
Top Forums UNIX for Beginners Questions & Answers Using sed to split hex string Post 303037249 by drl on Saturday 27th of July 2019 08:15:18 AM

Hi.
Code:
echo "1C 50 A9 D3 8B B0 24 9C 14 1C 50 A9 D3 8B B0 24" |
fold -12 |
sed '2~2a\
'

producing:
Code:
1C 50 A9 D3 
8B B0 24 9C 

14 1C 50 A9 
D3 8B B0 24

Where the GNU extension '2~2' starts with line 2, then after each 2nd line adds a newline.

On a system like:
Code:
OS, ker|rel, machine: Linux, 3.16.0-7-amd64, x86_64
Distribution        : Debian 8.11 (jessie) 
bash GNU bash 4.3.30
fold (GNU coreutils) 8.23
sed (GNU sed) 4.2.2

Best wishes ... cheers, drl

hex2bdf-split

HEX2BDF-SPLIT(1)					      General Commands Manual						  HEX2BDF-SPLIT(1)

NAME

       hex2bdf-split - Convert a GNU Unifont .hex file into single-width BDF fonts.

SYNOPSIS

       hex2bdf-split n < input_font.hex > halfwidth_output_font.bdf
       hex2bdf-split y < input_font.hex > fullwidth_output_font.bdf

DESCRIPTION

       hex2bdf-split  reads  a sorted GNU Unifont .hex file (sorted with the Unix sort utility) from stdin and writes a BDF version of the font to
       stdout.	This utility was adapted from the original hex2bdf script to accomodate charcell behavior in older  X11  implementations.   It	is
       present	for  historical  reasons,  but will probably be removed in a future distribution.  Dependency on this program is discouraged.  The
       main software application written to use the GNU Unifont, the international editor Yudit, does not need a split font.  In addition, the GNU
       Unifont now has a TrueType version that makes most other use of the BDF version obsolete.

       hex2bdf-split  takes  one  argument:  "y" or "n".  If "n" is specified, the output font is set to half-width (8 pixels wide) and "-h-" (for
       half-width) appears as the X Logical Font Descriptor (XLFD) ADD_STYLE_NAME value.  If "y" is specified, the output font	is  set  to  full-
       width (16 pixels wide), and "-f-" (for full-width) appears as the X Logical Font Descriptor (XLFD) ADD_STYLE_NAME value.

FILES

       *.hex GNU Unifont font files
