Batch file to check when it was lat run?

[TheSpecial1]

Hi,

I am a newbie to batch files.

I am wanting to write a batch file to rename a directory to originalname_yymmdd.

However before the folder rename is done, i need the batch file to check when it was last run. If it was run less than 7 days then i don't want it to perform the rename.

I need to do this without using scheduled tasks.

Any help provided would be greatly appreciated.

Thanks

then use a file that will store something to indicate its last run. eg a date.

1. I am wanting to write a batch file to rename a directory to originalname_yymmdd.

Code: [Select]

for /f "tokens=1-3 delims=/ " %%A in ("%date%") do set yymmdd=%C%B%A
set org=ORIGINALNAME
ren %org% %org%%yymmdd%2. However before the folder rename is done, i need the batch file to check when it was last run. If it was run less than 7 days then i don't want it to perform the rename.

Code: [Select]

set /p old=<date
set /a old2=old+7
if not %yymmdd% GEQ %old2% (
echo Rename will not be performed.
pause > nul
exit
)

Total code:

Code: [Select]

@echo off
for /f "tokens=1-3 delims=/ " %%A in ("%date%") do set yymmdd=%C%B%A
set org=ORIGINALNAME
set /p old=<date
set /a old2=%old%+7
if not %yymmdd% GEQ %old2% (
echo Rename will not be performed.
pause > nul
exit
)
ren %org% %org%%yymmdd%
echo %yymmdd% > date
Note that you have to put the current date in yymmdd format in date before you run it for the first time.

@TheSpecial1

Code: [Select]

@echo off
if not exist date.txt echo First run! > date.txt

echo.%date% %time% >date.txt
pause

That was a response. I was responding to each of the OP "questions" individially, then put them together.

Not your fault. You're just here to help out (and possibly to be helped as well lol).

Hi thanks for everyones help.

I have tried to run the code you provided in a batch file, however it is renaming the yymmdd to BA.
Therefore if i try this code on a folder named 'test' then the batch file will rename the folder to 'testba'.
What am I doing wrong here?

[TheSpecial1]

I have sorted it!

thanks

Hi,

This is how far i have got with the code (see below). However I have changed the system date on my PC to more than 7 days later and the code will not run. It is will not go past 'rename will not be performed'.

I think it's because its going into a new month (May)?

Can someone please help?

Code: [Select]


@echo off

for /f "tokens=1-3 delims=/ " %%A in ("%date%") do set yymmdd=%%C%%B%%A
set org=test

if not exist date.txt echo.%date% >date.txt

set /p old=<date.txt
set /a old2=%old%+7
if not %date% GEQ %old2% (
echo Rename will not be performed.
pause > nul
exit
)
ren %org% %org%%yymmdd%
echo %date% > date.txt

pause

you can't really do date calculation like that with batch.

[TheSpecial1]

Can you suggest any possible ways round this, any other ways to achieve the same result?

[devcom]

Code:
Wscript.echo eval(WScript.Arguments(0))

Save this script as Evaluate.vbs

Now, (cumbersome) either call it by

cscript //nologo "Path to\evaluate.vbs" "valid VBS expression" [quotes not always needed but advised]

http://www.computerhope.com/forum/index.php?topic=77361.0

so...

you need to use for loop:

Code: [Select]

for /f "tokens=1-3 delims=/" %%a in ('cscript //nologo evaluate.vbs date+7') do (echo %%a %%b %%c)

Hi

I am a bit confused with this.

How can i implement this within my code?

thanks

[devcom]

try this:

Code: [Select]

@echo off

for /f "tokens=1-3 delims=-" %%A in ('cscript //nologo evaluate.vbs date') do set yymmdd=%%A%%B%%C
set org=test

if not exist date.txt cscript //nologo evaluate.vbs date >date.txt

set /p date=<date.txt
for /f "tokens=* delims=-" %%A in ('cscript //nologo evaluate.vbs date+7') do set date7=%%A

if not %date:-=% GEQ %date7:-=% (
echo Rename will not be performed.
pause >nul
exit
)
ren %org%.txt %org%_%yymmdd%.txt
cscript //nologo evaluate.vbs date >date.txt

echo. DONE!
