Ok, the following alias ought to work:

alias tsize "(cd $HOME ; echo '#include <sys/stat.h>\
main(argc,argv) int argc;char **argv;{int t=0;struct stat s;\
while(--argc){stat(*(++argv),&s);t+=s.st_size;}\
printf("%d",t);}' >foo.c ; cc -o foo foo.c) ; $HOME/foo"

A bit slow for those small jobs but if you're talking Gb files it'll
work great :-).

I use shell scripts called "bytes" and "blocks".  They are:

bytes:
   /bin/ls -l $* | awk '{sum = sum + $4} END {print sum}'

blocks:
   du -s $* | awk '{total += $1} END {print total}'

(System V users may need to adjust the field number in the first one.)

The "blocks" script gives me total blocks used by specified files and
directory subtrees.
