Greetings.  I have written a small shell script to modify the login prompt 
at certain intervals, just for entertainment purposes.  The when I run the 
script from the shell prompt it runs fine, but when I execute it as cron 
job, I receive several errors in via email.  I am using Vcron as the cron 
daemon.

The crontab entry is as follows:

*/15 * * * *     root    /etc/init.d/issue

The script /etc/init.d/issue contains the following:
********************************************************
#!/bin/bash

R=$(cat /etc/gentoo-release | awk '{ print $5,$6 }')
C=$(cat /proc/cpuinfo | grep 'model name' | awk '{ print $4,$5,$6 }')
CS=$(cat /proc/cpuinfo | grep 'cpu MHz' | awk '{ print $4 }')
CB=$(cat /proc/cpuinfo | grep 'bogomips' | awk '{ print $3 }')
K=$(uname -r)
H=$(/bin/hostname -f)
M=$(( `dmesg | grep "Dentry" | awk '{print $9}'` / 1024 ))
KS=`dmesg | grep "Swap" | awk '{print $3}'`
S=$(( ${KS%k} / 1024 ))
U=$(uptime)
F=$(fortune 40% calvin 30% hitchhiker 10% chalkboard 10% starwars 10% bofh-
excuses)
