Extract the date with Ms-dos

Hello,

an extremely simple way to get the system date in the format DD_MM_YYYY with MS-DOS in a single line in a batch file is as follows:

set thedate=%date:/=_%

Here we indicate that we need to replace / with _

You can execute %date:/=_% in DOS and it will indeed display the date in the format DD_MM_YYYY

I tried the method provided by poulpenstring. It works for responding to toto. We created a *.bat

set my_file=d:\tes-%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.txt
echo head> %my_file%

it generates a file tes-20031208.txt. In DOS, by typing help set
you will get the online help.

Hello everyone :)

I used this topic to create an automatic backup batch.
The file to be backed up will be renamed with the date and then the time.

The code is as follows:

rename "%userprofile%\desktop\FILE.xls" FILE.xls_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%_%Time:~-11,-9%%Time:~-8,-6%%Time:~-5,-3%.xls

Which gives a file named:
FILE_20040420_114238.xls

Everything works perfectly from 10:00.00 to 23:59.59 :))
But the moment the ten's digit (for the hour) goes to 0 (that is, 00h, 01h, up to 09h), it causes an error :/

FILE_20040420_

Because the variable that contains the ten's digit is actually half empty; it consists of:
%Time:~-11,-10% => ten's digit
%Time:~-10,-9% => unit's digit
When there is no ten's digit, well there is something other than 1 or 2, but what?

FILE_20040420_?14238.xls

What is this character??

If I know it, I can replace it with 0:

SET ten %Time:~-11,-10% If %ten% == "unknown_character" SET %ten% 0

Thank you very much for any help or advice you can provide!

Thank you and well done Philippe, for this example rich in terms of code and comments, which I am eager to copy/paste in case of need.
Have a good day.

Hello,

Just a quick note regarding the manipulation with dates... I just noticed that unfortunately, depending on the operating system, the results are different, or even non-functional. This is specifically about "DOS," which can vary depending on whether you are using ... win95, win98, win98SE, 2000, or XP.

For example, under 95 and certain versions of 98, the function "date /T" does not work, and it is impossible to get the date without waiting for a response... (that's what the /T is for, I believe).

Anyway, there is always a possibility, or even to look online for Unix functions that work under MS/DOS.

Have a good evening.

Hi,
If you want to play with batch files, check out the website http://www.robvanderwoude.com/
You will find everything about everything.

See you!

Oufff after tinkering I made it :)
I propose the following code:

@Echo off SET ten=A%time:~0,1%B if A1B==%ten% goto OK if A2B==%ten% goto OK :ZERO SET ten=0 goto fin :OK SET ten=%time:~0,1% goto fin :FIN rename "%userprofile%\desktop\file.xls" file_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%_%ten%%Time:~-10,-9%%Time:~-8,-6%%Time:~-5,-3%.xls

THANK you very much for your help!!
and thank you also for the excellent link.
Take care :)

Well, I had 2 minutes and 30 seconds ahead of me...

Here is a complete example if we assume your files are on C:\ and you are copying them to D:\

The example is intentionally simplistic; you can potentially optimize it with loops or other labels... (if you feel like it)

set my_file=c:\bases_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.FIC
copy %my_file% d:\
set my_file=c:\bases_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.NDX
copy %my_file% d:\
set my_file=c:\histo_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.FIC
copy %my_file% d:\
set my_file=c:\histo_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.NDX
copy %my_file% d:\
set my_file=c:\reglem_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.FIC
copy %my_file% d:\
set my_file=c:\reglem_%Date:~-4%%Date:~-7,-5%%Date:~-10,-8%.NDX
copy %my_file% d:\

(all in a .bat file of course)

Have a nice day.

```batch
@echo off
set amj=%date:~6,4%%date:~3,2%%date:~0,2%
set h=%time:~0,2%
set m=%time:~3,2%
set s=%time:~6,2%
if %h% lss 10 set h=0%h:~1,1%
set hms=%h%%m%%s%
rar a -m3 -ep c:\contact-%amj%-%hms%.rar c:\contact.doc
move c:\contact-%amj%-%hms%.rar E:\backup\
pause
```

date /T > date.txt

you will almost have what you want in the file date.txt:
Thu 07/24/2003

Dans ton fichier date.txt, tu fais Édition > Rechercher > et tu remplaces "/" par "_".

I tried the command under Dos but it creates a %Date%.txt file
can someone help me?

command /e:2000 /c for %%i in (1 2) do prompt set _d=$d$_ | find "$" /v >{t}.bat
for %%c in (call del) do %%c {t}.bat

Hello everyone, I would like to know some uses of DOS for programming!

Do you have any programs?

Hello;
How to rename a file
e.txt to 12:59.txt using a .bat file
e.txt: file to rename
12:59.txt: desired name, 12:59 is the current time
It would be fabulous for automating backups...

I tried to replace the variable in question: if it contains neither 1 nor 2, I set it to 0 :)
but I can't even test it... :(
help !!

@Echo off SET dizaine=%Time:~-11,-10% @echo original var : %dizaine% IF %dizaine% == 1 goto fin IF %dizaine% == 2 goto fin SET dizaine=0 GOTO fin :fin @echo var after test : %dizaine% pause

Here is a way...
try the following batch and modify it as needed...
especially for creating the file, I didn't take care of that part...

it's a bit of a stretch but it works...

______________________________________________________

echo off
rem *** add a zero in front of the hour****
set wcontrol=%time:~0,1%
set wcontrol=A%wcontrol%B
echo %wcontrol%

if A1B==%wcontrol% goto OK
if A2B==%wcontrol% goto OK

:ZERO
echo 0%time:~1,10%.xls
goto fin

:OK
echo %time%.xls
goto fin

:FIN
echo on

______________________________________________________

Good luck and keep me posted.

Just a heads up... The problem with the SET - DATE and TIME commands is their "non-portability" in certain cases. Indeed, as I mentioned a bit earlier, a batch containing these commands might not work under W95, W98, 2000, or even XP, depending on the version of DOS that is embedded.
That’s why, in my opinion, the ideal solution would be to use small functions (or exe and com programs) found in the Unix world or to create them yourself, which would be usable on any platform.

If you have any ideas in that direction... I'm all ears. Thanks in advance.

For example, vardate.exe would return, depending on its parameters, a variable in different formats like DD_mm_yy or HH_dd_mm or even MON (for Monday=) etc. etc. etc.

Hello,
under Win98, it's not working.
I want to rename a file with today's date.
All of this executed in a .bat

Does anyone have an idea?
