>Description:
By default, user's crontab would have below environment variables 

LOGNAME=user1
PATH=/usr/bin:/bin
PWD=/usr/home/user1
HOME=/home/user1
USER=user1
SHELL=/bin/sh

When the script is invoked/test in command line, it worked.
When the script is invoked by cronjob, some part of the script failed to run because /usr/sbin/chown is not in the search PATH.

It is not convenient.
>How-To-Repeat:
always
>Fix:
configure user's crontab to include PATH like /etc/crontab

PATH=/etc:/bin:/sbin:/usr/bin:/usr/sbin
