Trying to use sed in some stuff and i never want to have to write this kinda crap again so..
grep '^D' Filename | sed -e 's/\(^.\{43\}\)0\(.*\)/\1M\2/g'
That looks for any line in “Filename” that starts with D… then if the 44th character is 0, replace it with an M.
kgo.
grep "^D" Filename | sed -e 's/.*/&XX/'
That looks for anything in Filename and adds “XX” to the end of the line..
