Hi,
You can also do this in sed, which I use when I need speed:
(sed "s/^/file1*/" file1;sed "s/^/file2*/" file2)|sort -t* -k2
Cheers,

Or just do it in awk:
awk '{printf("%s*%s\n",FILENAME,$0)}' file1 file2 | sort -t*
- -k2,999
Gotta say I was surprised that the '*' delimeter in the sort
command didn't need to be escaped with \, but it doesn't.
-- The shell will expand the * if it's on its own, but this will only
match files starting with -t (that would probably have been created by a
typo :-)
Cheers,
Ken
