Delete 5 days older files from sftp

As one of our requirement was to connect to remote Linux server through SFTP connection and delete some files which are older than 7 days.

I used the below piece of code for that,

Code:

SFTP_CONNECTION=`sftp user_id@host ... 
cd DESIRED_DIR;
find /path/to/files* -mtime +5 -exec rm -rf {} \;
bye
END`

But unfortunately, "find" command does not work with "SFTP" connection, and as a result, iam unable to remove files from remote server.

I even can not use "SSH" for security purpose. And the script is fired from "ksh".

So my question is, how can we delete files from remote server through "SFTP".

Or, is there any alternative command of "ls" which does the exactly same thing as,

Code:

"find /path/to/files* -mtime +5 -exec rm -rf {} \;"

sftp-server

SFTP-SERVER(8)						    BSD System Manager's Manual 					    SFTP-SERVER(8)

NAME

     sftp-server -- SFTP server subsystem

SYNOPSIS

     sftp-server [-ehR] [-d start_directory] [-f log_facility] [-l log_level] [-u umask]

DESCRIPTION

     sftp-server is a program that speaks the server side of SFTP protocol to stdout and expects client requests from stdin.  sftp-server is not
     intended to be called directly, but from sshd(8) using the Subsystem option.

     Command-line flags to sftp-server should be specified in the Subsystem declaration.  See sshd_config(5) for more information.

     Valid options are:

     -d start_directory
	     specifies an alternate starting directory for users.  The pathname may contain the following tokens that are expanded at runtime: %%
	     is replaced by a literal '%', %h is replaced by the home directory of the user being authenticated, and %u is replaced by the user-
	     name of that user.  The default is to use the user's home directory.  This option is useful in conjunction with the sshd_config(5)
	     ChrootDirectory option.

     -e      Causes sftp-server to print logging information to stderr instead of syslog for debugging.

     -f log_facility
	     Specifies the facility code that is used when logging messages from sftp-server.  The possible values are: DAEMON, USER, AUTH,
	     LOCAL0, LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7.  The default is AUTH.

     -h      Displays sftp-server usage information.

     -l log_level
	     Specifies which messages will be logged by sftp-server.  The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
	     DEBUG2, and DEBUG3.  INFO and VERBOSE log transactions that sftp-server performs on behalf of the client.	DEBUG and DEBUG1 are
	     equivalent.  DEBUG2 and DEBUG3 each specify higher levels of debugging output.  The default is ERROR.

     -R      Places this instance of sftp-server into a read-only mode.  Attempts to open files for writing, as well as other operations that
	     change the state of the filesystem, will be denied.

     -u umask
	     Sets an explicit umask(2) to be applied to newly-created files and directories, instead of the user's default mask.

     For logging to work, sftp-server must be able to access /dev/log.	Use of sftp-server in a chroot configuration therefore requires that
     syslogd(8) establish a logging socket inside the chroot directory.
