Problem with BASH and [ ! -t 0 ] test.

[GESBBB]

I am using this snippet of code in a bash script that is run via CRON.
 
 
<snippet>
# See if we are running via CRON
    if [ ! -t 0 ]
      then
# Use the BASH RANDOM function to generate a random number between 0 & 32767
        RESTING=$((RANDOM/60))
        sleep ${RESTING}
    fi
</snippet>
 
 
It runs fine from the console; however, when run via CRON, it outputs this error message.
 
Tput: No terminal type specified and no TERM environmental variable.
 
I have Googled about, yet I cannot find an answer. Perhaps some Bash guru can assist me.
