Ftp bash script appends to file using cron instead of coping new file
I have a bash script that is running a mysql query and creating a csv file with a time stamp. It then uploads that to a ftp server. Everything works great when I manually run it. But then I have a cron job set to run every monday, wednesday and friday at 5am est. When the cron job runs, it appends to the last file. For example, the file that ran wednesday is called 15-07-08_report.csv. On Friday the cron job runs and instead of creating a new file called 15-07-10_report.csv, it just appends to the file called 15-07-08_report.csv. If I run it manually without the cron job, the bash script will create a new file on the ftp server called 15-07-10_report.csv and leave the file from wednesday. That what I want to happen when the cron job runs.

bash script:
Code:
#!/bin/bash
#DB server details

server_ip='mysql_server.com';

db_user='user';
db_pass='password';
db_name='db_name';


#Delete all previous csv files

rm *.csv

#create new file

csv_file="$(date -d now +%y-%m-%d)_report.csv";

touch $csv_file

#Query to be execute in MySql and save data in csv file

mysql -u$db_user -p$db_pass -h$server_ip < /var/www/html/tools/report-script/report.sql $db_name | sed 's/\t/","/g;s/^/"/;s/$/"/;s/\n//g' >> $csv_file

#Open FTP and put files there
echo "start ftp"

#Your FTP IP or URL
HOST="ftp.upload.com"

#FTP user name
USER="user_me"
echo "pass"
#FTP user password
PASSWD="my_pass"

echo "change"

#Change to directory where the original csv file is located

cd /var/www/html/tools/report-script

echo "transfer file"
ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD

!#Folder on the FTP server you want to save to.  By default it will save to the user's home directory
cd /folder

!# Turn off prompting yes or no to transfer file
prompt

!#copies the cvs file to ftp server
mput *.csv

quit
END_SCRIPT
exit 0

cron job:
Code:
0 5 * * 1,3,5 /var/www/html/tools/report-script/test_report.sh

Any help is much appreciated. I can't figure out why the behavior would be different by using cron to run the script vs running it manually. Thanks!
