Batch file for one current date in text fileSolved/Closed

Question

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

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.

this works well... removes "/"

FOR %%A IN (%Date:/=%) DO SET Today=%%A
ren test.txt "test "%TODAY%.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.

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"

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!

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.
