Batch file for one current date in text file

Solved/Closed

Hello,
I need a batch file to get the current date and time of my computer and put it in a text file every time I run it.But I need the most current date&time to replace the previous within the same text file, so that my file can have only one record, even if I run it multiple times.
I found this code: 
echo %date% %time% >> log.txt

But this one just adds the next date under the previous one.
Your help would be greatly appreciated. Thanks in advance!

Hi,

Remove one of the '>' and you have solved it.

It should look like this:
echo %date% %time% > log.txt

these are some simple string manipulations to get Date, Time, and DOW if you would rather not use a FOR

REM - Create Date and Time strings
set Today=%date:~10,4%%date:~4,2%%date:~7,2%
set Now=%time:~0,2%%time:~3,2%%time:~6,2%
set DOW=%date:~0,3%

To Rename Any File With Date And Time Padded

set dd = %date% %Time%

Ren File_To_Rename.txt MyFile__%dd:~0,2%_%dd:~3,2%_%dd:~6,4%___%dd:~11,2%_%dd:~14,2%.txt


Output
--------
MyFile__22_05_2009__6_20.txt

Close....
1) To clarify: The rename command is issued as a single line
2) The variable positions are not correct for English language WinXP but close enough to figure out what they should be.
Otherwise, great tip!!!

Your line does an apend:
echo %date% %time% >> log.txt

The following line wil overwrite the existing file:
echo %date% %time% > log.txt

ren test.txt "test "%TODAY%.txt

Is this a POS application ? I think you are looking for a file that's for yesterday - so if today is 02/24, you are looking for file name with "0223". Is it correct ?

Anyway, here is a biterscripting script. 

# Script CheckYesterday.txt
var str file, date
# Get yesterday's date.
set $date = addtime(diff("-1000000"))
# Get only the mmdd part.
chex "8[" $date > null ; chex "4]" $date > null
# The file name will be "C:/somefolder/TRB0"+$date+".zip"
set $file = "C:/somefolder/TRB0"+$date+".zip"
# Check if file exists.
af $file
if ($fexists)
    echo "File " $file " exists."
else
    echo "File " $file " does not exist."
endif


Copy and paste this script into file "C:/Scripts/CheckYesterday.txt", change "C:/somefolder" to the coorect folder path, then execute this command in biterscripting each morning. 

script "C:/Scripts/CheckYesterday.txt"

You can use the gettime() function in bierscripting to get the current date and time and rename files using that. For example, the following script will rename all files in folder "C:/folder" by appending a timestamp to file names. 


# Script AppendTimestamp.txt
var str folder, list, file, extn, name
lf -n "*" $folder ($ftype=="f") > $list
while ($list <> "")
do
    lex "1" $list > $file ; stex -p "^/^l[" $file > $name ; stex "[^.^l" $name > $extn
    system rename ("\""+$file+"\"") ("\""+$name+"_"+gettime()+$extn+"\"")
done




To run the script, copy and paste the script into file C:/Scripts/AppendTimestamp.txt, then enter the following command in biterscripting 

script "C:/Scripts/AppendTimestamp.txt" folder("C:/somefolder")



It will rename all files in folder "C:/somefolder" accordingly.

I am needing to create a batch file the will display a message on the screen each morning and let me know a certain file was created each night at my "day end"

Each night when my store closes, I have a file that is created and zipped up to a certain directory with the name TRB00222.zip
TRB00221.zip
TRB00220.zip
ect...

I have created a batch file to screen pop notepad and give me a message with the current date that the file exist.
But what I dont know how to do is put in the "if exits" statement based the "modified" date of the file.

Can someone help me?

Use this instead:

echo %date% %time% > log.txt

>> appends to a file.
> overwrites a file. Use with caution.

Protip: Use a unix system like FreeBSD and save yourself a lot of grief.

You can use this..
REM mmddyyyy, just switch it around if you want the yyyy to be the first
For /F "tokens=2-4 delims=/ " %%a in ("%DATE%") DO SET MDY=%%a%%b%%c
REM hhdd, if you need the secs you can add the 3rd token
FOR /F "tokens=1,2 delims=:" %%d in ("%TIME%") DO SET ORAS=%%d%%e

REM then just output it to a file each time
echo > %MDY%.%ORAS%
REM or you can run a command and output it and add an ext.
whatever cmd > %MDY%.%ORAS%.TXT

this code will tell it to delete the old one and replace it:
del log.txt
echo %date% %time% >> log.txt

basically add the del log.txt first so it will delete it and then afterwards create it again hop this help

This is the code to display current date and time, tab delimited:

@echo off
echo/|set /p =%date% >datetimelog.txt
time/t>>datetimelog.txt

@echo off & setlocal EnableDelayedExpansion
set TAB=
set SPACE=
for /f "delims=" %%i in (datetimelog.txt) do (
set row=
set count=0
for %%j in (%%i) do (
set /A count=!count!+1
set char=%TAB%
if !count!==3 set char=%SPACE%
set row=!row!%%j!char!
)
set row=!row:~0,-1!
echo.!row! > datetimelog.txt
)


It will display something like this :

04/06/2010 03:41 PM

Hope this helps someone else too! Thanks!

Answer 10 / 10

Here's your long awaited answer...

echo %time% %date%>text.txt

note: use only one ">" in the command line so it will erase the previous txt file and replace it with the text you want.

I was wondering if you gurus can give me some direction...

I run a Specials Menu at a restaurant using powerpoint. There are two specials files (lunch.pps and dinner.pps)
When this system reboots, I want a batch file to determine which powerpoint file to open based on what time it is.

For instance, if it's anywhere between 11am and 3pm, open the lunch file. If its any other time, run the dinner.pps file. Make sense?

Does anyone know what the syntax is to do this?

The above will check the hour is e.g. 3pm
