sed - insert spaces on line

Simpson — Mon, 09 Feb 2009 16:34:13 GMT

I have a file that contains a date on each line. I would like to up date the formate by doing the following:

orig_file:
20090208
20090209

new_file
2009 02 08
2009 02 09

Any help would be appreciated.
Thanks
Mike

Instead of sed, try awk:

awk '{printf("%s %s %s\n",substr($0,1,4),substr($0,5,2),substr($0,7,2))}' < orig_file > new_file

$ sed -e 's/$....$$..$$..$/\1 \2 \3/' old.txt > new.txt
