Instead of a while, can you use cron? It is usually more efficient than having a resident process sleeping.

Code:
#!/bin/ksh
# usage.shl
for dir in /directory1/subdir directory2/subdir
do
echo "$dir $( du $dir |wc -l)" 
done > ./message
mailx -s 'dir usage' me@mycompany.com < ./message

Using crontab

Code:
# five minutes after every hour
5 * * * * *  /path/to/usage.shl 2 > /path/to/usage.log

no crontab
Code:
#!/bin/ksh
# usage.shl

while :
do
 for dir in /directory1/subdir directory2/subdir
 do
   echo "$dir $( du $dir |wc -l)" 
 done > ./message
 mailx -s 'dir usage' me@mycompany.com < ./message
 sleep 3600
done

This execution time will drift over time because sleep is not guranteed to "wake up" precisely because of system load.

bundle

BUNDLE(1)						      General Commands Manual							 BUNDLE(1)

NAME

       bundle - collect files for distribution

SYNOPSIS

       bundle file ...

DESCRIPTION

       Bundle  writes  on  its	standard output a shell script for rc(1) or a Bourne shell which, when executed, will recreate the original files.
       Its main use is for distributing small numbers of text files by mail(1).

       Although less refined than standard archives from ar(1) or tar(1), a bundle file is self-documenting and complete;  little  preparation	is
       required on the receiving machine.

EXAMPLES

       bundle mkfile *.[ch] | mail kremvax!boris
	      Send  a  makefile  to Boris together with related and files.  Upon receiving the mail, Boris may save the file sans postmark, say in
	      gift/horse, then do

       cd gift; rc horse; mk

SOURCE

       /rc/bin/bundle

SEE ALSO

       ar(1), tar(1), mail(1)

BUGS

       Bundle will not create directories and is unsatisfactory for non-text files.
       Beware of gift horses.
