FTP command to get most recent file

Hello Experts...
dir of FTP will list all the files in the directory. Is there any command or option of dir that will give me the most recent file only?
Since I couldn't find any such thing, I thought of creating a log file (of FTP results) and work on this log file to determine the most recent file name. Then go back to FTP and get this file. Does it sounds good?

regards,
juzz4fun

When you post it helps if we know the OS you use and the shell (ksh, bash, etc).

The reason is: in this case there is a specific answer for Linux with GNU date.

I assume there is no such FTP command that gives me only the most recent file..
To get the work done, I have created a log file which contains the dir's output as shown:

Code:
Connected to XXX.XXX.XXX.XXX.
220 EFT Server 6.4.10 Build XX.XX.XXXX.X
331 Password required for XXXXX.
230 Login OK. Proceed.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> 250 Folder changed to "/XX/XXXXXXX/XXXX/XXXX".
ftp> 200 Command okay.
150 Opening ASCII mode data connection for file list.

226 Transfer complete. 964 bytes transferred. 964 bps.
964 bytes received in 0.00022 seconds (4316.40 Kbytes/s)
ftp> 221 Service closing control connection.

Then I replaced Jan with 1, Feb with 2 and so on... this part of script I have written in scr file and execute it like ./scr. Output of scr is piped to below commands to get the most recent file name...
scr also contains grep '^-.*xlsx$' to get only the required rows from log file...

./scr | sort -k8n -k6n -k7n | tail -1 | awk '{print $NF}'

.... which gives me output as A111230.xlsx

Is there any way I can achieve the same result in some shorter way?
