Can ls show total Kbytes of "foo*"?

[Rouben Rostamian]

I wonder if there is an obvious way to compute the total size of all
"foo*" files in a directory.  The only way I know how is the ridiculously 
complicated construction:

ls -1s foo* | awk 'BEGIN{size=0} {size += $1} END{print "total: " size}'

(which I alias to something.)  I run ULTRIX.  The command "ls -s" in ULTRIX
lists the files in the current directory, gives the size of each file in
kilobytes, and  also gives the total kilobytes for the files in that
directory.

It stands to reason to expect that the command "ls -s foo*" would provide
the corresponding information for all files "foo*" in the directory.
Alas, it does not work that way;  although the size of each "foo*"
is displayed, the total kilobytes for the "foo*" files is not.

Am I missing something obvious?
