while read...
... < file
works bad when file doesn't end with newline char.

This should work:
Code:
#!/bin/sh
# Usage: count.sh FILE

wc -l <"$1"  # not print the name of FILE

DONE=false
until $DONE; do
    read s || DONE=true
    words=0
    for w in $s; do
        words=$((words+1))
    done
    echo $words
done <"$1"

Code:
./count.sh FILE | head -1

for number of lines,
Code:
count.sh FILE | tail -n+2

for numbers of words in each line.

It's, of course, easier to use awk.
