Pulling Windows2003 log files

[Cooldmitriy]

I am trying to pull Windows2003 server log files via FTP.
The server creates new log files every day. I need to pull them daily and always for the prior day. Example: On Monday I pull log files for Sunday, on Tuesday for Monday and so on.
Log files have the following format: exYYMMDD.log
I know how to get current date and extract year, month and date portion. But how do I subtract 1 day from it?

Thank you all in advance.

Copy the functions :jdate , :date2jdate , and :jdate2date to the end of your batch script.

http://www.dostips.com/DtCodeCmdLib.php#jdate
http://www.dostips.com/DtCodeCmdLib.php#date2jdate
http://www.dostips.com/DtCodeCmdLib.php#jdate2date

Then you can calculate the date like this:

Code: Select all

call:jdate d "%date%"
set /a d-=1
call:jdate2date d YYYY MM DD
set logfile=ex%YYYY:-2%%MM%%DD%.log

Hope this helps

Thank you DosItHelp ! For some reason I can't trim down CC portion of YYYY. YYYY:-2% doesn't seem to work
I am not sure what I did wrong. Here's my entire batch file for your review:

call:jdate d "%date%"
set /a d-=1
call:jdate2date d YYYY MM DD

Sorry I didn't try it out:
It had two errors:

1. to extract CC from YYYY use:
%YYYY:~-2%

2. to make sure MM and DD are always two digits, e.g. with leading zero, use:
set MM=00%MM%&set DD=00%DD%
set DD=%DD:~-2%&set MM=%MM:~-2%

You will also need to ensure the script stops before running into the functions.

The idea is to have the functions pasted at the end of the script, so that the main script at the beginning stays clean.


The following should work:

Code: Select all

@ECHO OFF
call:jdate d "%date%"
set /a d-=1
call:jdate2date d YY MM DD
set MM=00%MM%&set DD=00%DD%
set DD=%DD:~-2%&set MM=%MM:~-2%&set YY=%YY:~-2%
set logfile=ex%YY%%MM%%DD%.log
ECHO. %date% - %logfile%

ECHO.
PAUSE
GOTO:EOF
