Overwriting file with sftp

I have a script, which runs through cronjob every night 9 PM. It is supposed to do following tasks --
1- Connect to ftp.testsite.com via user redtest
2- Fetch file red_bill.txt to my local server, where my script is residing.
3- Rename red_bill.txt to red_bill.V01.txt everyday on sftp server.
4- Make a copy of red_bill.txt on my local server
5- Send status mail to team.
Everything is ok, except 3. It seems, there is existing red_bill.V01.txt from previous night, so it is not able to overwrite that file. Can somebody help me with this script.
Code:
#!/bin/sh
HOST='ftp.testsite.com'
USER='redtest'
FILE='red_bill.txt'
cat > /tmp/script_file_$$ <<EOF
    get ${FILE}
    rename ${FILE} red_bill.V01.txt
    exit
EOF
 sftp -b /tmp/script_file_$$ $USER@$HOST
exit_status=$?
rm -f /tmp/script_file_$$
if [ $exit_status != 0 ];then
   echo "SFTP file transfer is failed for file $FILE" |mailx -s "FTP Redtest status"  xxxx@xxxx.com
else
echo "SFTP file transfer is successfull for file $FILE" |mailx -s "FTP Redtest status" xxxx@xxxx.com
cp $FILE $FILE.`date +%m%d%y`
fi

NAME
Git-ftp - FTP done the Git way SYNOPSIS
git-ftp [actions] [options] [url]... DESCRIPTION
This manual page documents briefly the git-ftp program. Git-ftp is a FTP client using Git to determine which local files to upload or which files should be deleted on the remote host. It saves the deployed state by uploading the SHA1 hash in the .git-ftp.log file. There is no need for Git (http://git-scm.org) to be installed on the remote host. Even if you play with different branches, git-ftp knows which files are different and only handles those files. No ordinary FTP client can do this and it saves time and bandwith. Another advantage is Git-ftp only handles files which are tracked with Git (http://git-scm.org). ACTIONS
init Initializes the first upload to remote host. push Uploads files which have changed since last upload. catchup Uploads the .git-ftp.log file only. We have already uploaded the files to remote host with a different program and want to remember its state by uploading the .git-ftp.log file. show Downloads last uploaded SHA1 from log and hooks `git show`. add-scope <scope> Creates a new scope (e.g. dev, production, testing, foobar). This is a wrapper action over git-config. See SCOPES section for more information. remove-scope <scope> Remove a scope. help Prints a usage help. OPTIONS
-u [username], --user [username] FTP login name. If no argument is given, local user will be taken. -p [password], --passwd [password] FTP password. If no argument is given, a password prompt will be shown. -k [[user]@[account]], --keychain [[user]@[account]] FTP password from KeyChain (Mac OS X only). -a, --all Uploads all files of current Git checkout. -c, --commit Sets the SHA1 hash of last deployed commit by option. -A, --active Uses FTP active mode. -s <scope>, --scope <scope> Using a scope (e.g. dev, production, testing, foobar). See SCOPE and DEFAULTS section for more information. -l, --lock Enable remote locking. -D, --dry-run Does not upload or delete anything, but tries to get the .git-ftp.log file from remote host. -f, --force Does not ask any questions, it just does. -n, --silent Be silent. -h, --help Prints some usage information. -v, --verbose Be verbose. -vv Be as verbose as possible. --syncroot Specifies a directory to sync from as if it were the git project root path. --connections Number of simultanious connections (Linux only). --version Prints version. URL
The scheme of an URL is what you would expect protocol://host.domain.tld:port/path Below a full featured URL to host.exmaple.com on port 2121 to path mypath using protocol ftp: ftp://host.example.com:2121/mypath But, there is not just FTP. Supported protocols are: ftp://... FTP (default if no protocol is set) sftp://... SFTP ftps://... FTPS ftpes://... FTP over explicit SSL (FTPES) protocol DEFAULTS
Don't repeat yourself. Setting defaults for git-ftp in .git/config $ git config git-ftp.<(url|user|password)> <value> Everyone likes examples $ git config git-ftp.user john $ git config git-ftp.url ftp.example.com $ git config git-ftp.password secr3t $ git config git-ftp.connections 10 $ git config git-ftp.syncroot path/dir After setting those defaults, push to john@ftp.example.com is as simple as $ git ftp push SCOPES
Need different defaults per each system or environment? Use the so called scope feature. Useful if you use multi environment development. Like a development, testing and a production environment. $ git config git-ftp.<scope>.<(url|user|password)> <value> So in the case below you would set a testing scope and a production scope. Here we set the params for the scope "testing" $ git config git-ftp.testing.url ftp.testing.com:8080/foobar-path $ git config git-ftp.testing.password simp3l Here we set the params for the scope "production" $ git config git-ftp.production.user manager $ git config git-ftp.production.url live.example.com $ git config git-ftp.production.password n0tThatSimp3l Pushing to scope testing alias john@ftp.testing.com:8080/foobar-path using password simp3l $ git ftp push -s testing Note: The SCOPE feature can be mixed with the DEFAULTS feature. Because we didn't set the user for this scope, git-ftp uses john as user as set before in DEFAULTS. Pushing to scope production alias manager@live.example.com using password n0tThatSimp3l $ git ftp push -s production You can also create scopes using the add-scope action. All settings can be defined in the URL. Here we create the production scope using add-scope $ git ftp add-scope production ftp://manager:n0tThatSimp3l@live.example.com/foobar-path Deleting scopes is easy using the remove-scope action. $ git ftp remove-scope production IGNORING FILES
Add file names to .git-ftp-ignore to be ignored. Ignoring all in Directory config: config/* Ignoring all files having extension .txt in ./ : *.txt This ignores a.txt and b.txt but not dir/c.txt Ingnoring a single file called gargantubrain.txt: gargantubrain.txt EXIT CODES
There are a bunch of different error codes and their corresponding error messages that may appear during bad conditions. At the time of this writing, the exit codes are: 1 Unknown error 2 Wrong Usage 3 Missing arguments 4 Error while uploading 5 Error while downloading 6 Unknown protocol 7 Remote locked 8 Not a Git project KNOWN ISSUES &; BUGS The upstream BTS can be found at <http://github.com/resmo/git-ftp/issues>.
