How to download last modified file from remote server to local using PuTTY batch file

I have a query regarding the putty batch file. This is my .bat file:

C:
cd Program Files (x86)\PuTTY
pscp -2 -v -pw khair1 -sftp  abc@****.na.ab.com:/qwe/asd/tryu/*.csv.zip P:\Projects\abc\Test_bacth\Batch_download
pause"

So every week I have to give file name like /qwe/asd/tryu/**04242016***.csv.zip

How can I dynamically get all the file which is last modified.

Solution

You can use these commands to generate the today's stamp:

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if '.%%i.'=='.LocalDateTime.' set LDT=%%j
set STAMP=%LDT:~0,4%%LDT:~4,2%%LDT:~6,2%
echo %STAMP%

See How do I get current datetime on the Windows command line, in a suitable format for using in a filename?

Or use some more powerful SFTP/SCP client.

For example with WinSCP scripting, you can do:

"C:\Program Files (x86)\WinSCP\WinSCP.com" /command ^
    "open sftp://abc:password@****.na.ab.com/ -hostkey=""ssh-rsa 2048 xxxxxxxxxxx...=""" ^
    "get /qwe/asd/tryu/%%TIMESTAMP#yyyymmdd%%*.csv.zip ""P:\Projects\abc\Test_bacth\Batch download\""" ^
    "exit"

See documentation for the %TIMESTAMP% syntax.

If the timestamp is actually not today's, instead of specifying the timestamp, just download the latest file for each pattern/mask.

It's easy with WinSCP, just use the -latest switch:

"C:\Program Files (x86)\WinSCP\WinSCP.com" /command ^
    "open sftp://abc:password@****.na.ab.com/ -hostkey=""ssh-rsa 2048 xxxxxxxxxxx...=""" ^
    "lcd ""P:\Projects\abc\Test_bacth\Batch download""" ^
    "cd /qwe/asd/tryu" ^
    "get -latest *_cpg_aob_detail.csv.zip" ^
    "get -latest *_fmcg_cob_detail.csv.zip" ^
    ...
    "exit"
