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

LEARN ABOUT DEBIAN

fixnt

fixnt(1)							      Debian								  fixnt(1)

NAME

       fixnt - Filter for the Windows NT postscript printer driver.

SYNOPSIS

       fixnt < BADFILE.ps > GOODFILE.ps

DESCRIPTION

       The  Windows  NT  postscript  driver has a tendency to make broken postscript files, that are incompatible with psutils.  fixnt is a filter
       that fixes these problems, allowing the use of psnup(1).

       The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout.  It has no other form  for	invocation
       and takes no options on the command-line.

OPTIONS

       fixnt  takes no options.

BUGS

       fixnt does not check for NTPSOct94.  For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
	      sed 's/NTPSOct94/NTPSOct95/g'
       This is particularly important for Windows NT 3.5 users.

AUTHOR

       fixnt   was   written   by   Holger   Bauer   <Holger.Bauer@topmail.de>,  Michael  Rath	<rath@itsm.uni-stuttgart.de>,  and  Akim  Demaille
       <demaille@inf.enst.fr>.

REPORTING BUGS

       Report bugs to the Authors, but avoid sending large postscript files.

       Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
