Really?
$ M=0; N=0; for W in `find /usr -xdev 2>/dev/null`; do M=$(($M+1));
N=$(($N+${#W}+1)); done; echo $M $N

vs.
$ /bin/echo `find /usr -xdev 2>/dev/null`
bash: /bin/echo: Argument list too long
For the first case, the shell never tries to pass the list as command
arguments.
It builds the list internally, limited only by memory size, and
processes the
words one by one.
Is that peculiar to bash? I thought the `command` construct was
expanded by shells into the command line before being evaluated.
