Problem with output file generated by script when scheduled as a cron job

Hello --

I have created a script that is designed to output to file several commands that I am planning on running on our system. The script in question is as follows:

#!/bin/bash

# The commands that follow are designed to run checks on the SamFS system on the

# spinning disk arrays, and tape libraries.

# Remove the existing samfs_system_check.txt file before proceeding further.

rm -rf samfs_system_check.txt

# Insert the date and time the commands that will be run to the output file.

date > samfs_system_check.txt

sleep 5

# Run the 'samcmd a' command to generate information on the current status
