Why can't cron run one of my scripts [SOLVED]

Question

I'm confused why cron can't run one of my scripts which runs just fine interactively.  I see no errors in messages.log or crond.log.
My crontab:
$ crontab -l
# * * * * command to be executed
#| | | | |
#| | | | +----- day of week (0 - 6) (Sunday=0)
#| | | +------- month (1 - 12)
#| | +--------- day of month (1 - 31)
#| +----------- hour (0 - 23)
#+------------- min (0 - 59)
#MAILTO=""
25 20 * * * ~/bin/cpuz s
Here is the code to that script:
run() {
tmpfile=/tmp/.sensors_unique.txt # temp output
verbose=/tmp/.verbose_unique.txt # verbose temp output with three decimals
logfile=/scratch/unique.csv # data file to write
sensors >$tmpfile && sensors -u >$verbose
phys=$(grep Physical $tmpfile | cut -c 18-21)
c0=$(grep "Core 0" $tmpfile | cut -c18-21)
c1=$(grep "Core 1" $tmpfile | cut -c18-21)
c2=$(grep "Core 2" $tmpfile | cut -c18-21)
c3=$(grep "Core 3" $tmpfile | cut -c18-21)
vcc=$(grep in0_input $verbose | cut -c14-18)
fan1=$(grep fan1 $tmpfile | cut -c24-27)
pwm1=$(cat /sys/class/hwmon/hwmon3/device/pwm1)
per1=$(echo "scale=2; $pwm1/2.55" | bc)
fan3=$(grep fan3 $tmpfile | cut -c24-27)
pwm3=$(cat /sys/class/hwmon/hwmon3/device/pwm3)
per3=$(echo "scale=2; $pwm3/2.55" | bc)
fan4=$(grep fan4 $tmpfile | cut -c24-27)
pwm4=$(cat /sys/class/hwmon/hwmon3/device/pwm4)
per4=$(echo "scale=2; $pwm4/2.55" | bc)
fan5=$(grep fan5 $tmpfile | cut -c24-27)
pwm5=$(cat /sys/class/hwmon/hwmon3/device/pwm5)
per5=$(echo "scale=2; $pwm5/2.55" | bc)
dts=$(date +"%m-%d-%y %r")
[[ ! -f $logfile ]] && echo "dts,vcc,temp,core0,core1,core2,core3,120mm_rpm,120mm_pwm,140mm_rpm,140mm_pwm,comment" > $logfile
echo "$dts,$vcc,$phys,$c0,$c1,$c2,$c3,$fan4,$pwm4,$fan5,$pwm5,$comment" >> $logfile
if [ -n "$output" ]; then
echo "Vcore : $vcc"
echo "back : $fan1 ($pwm1/255) = $per1 %"
echo "top : $fan3 ($pwm3/255) = $per3 %"
echo "120mm : $fan4 ($pwm4/255) = $per4 %"
echo "140mm : $fan5 ($pwm5/255) = $per5 %"
fi
case "$1" in
s)
limit=600 # number of times to run
wait=2 # delay in sec before taking a new reading
echo running in silent mode...
x=0
while [ "$x" -lt "$limit" ]; do
x=$(( $x + 1 ))
run
sleep "$wait"s
done
v)
export output="not null"
export -f run
/usr/bin/watch run
echo "usage $0 {s|v}"
echo
echo "s) silent mode/logfile only"
echo "v) verbose mode/logfile + output"
exit 0

Answer 1

I hate to suggest something obvious to someone with 4000 posts (and such a scary avatar), but have you tried it with the full path: /home/user/... ?
Are you sure the script is not being run at all?
(edit -- never mind, I see the file lines in there)
