See which character each of the eight bytes in those numbers corresponds
too. Assuming that's what you were asking...
ben@magnesium:~/tmp$ cat t.c
#include <unistd.h>
int
main(void) {
long long a = 22322600044678729LL, b = 22322600044678990LL;
write(1, &a, sizeof a);
write(1, &b, sizeof b);
return (0);
}
ben@magnesium:~/tmp$ cc -Wall t.c
ben@magnesium:~/tmp$ ./a.out | hd
00000000 49 4e 20 56 49 4e 4f 00 4e 4f 20 56 49 4e 4f 00 |IN VINO.NO VINO.|
00000010
ok, who's going to give me the Perl one-liner to do that? It would
probably involve pack/unpack which I've never got on well with.
