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.

@helpmeh
is that question or response ?

@TheSpecial1

Code: [Select]

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

Oh ok  Sorry then

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?

@echo off

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

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



[gh0std0g74]

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)

[TheSpecial1]

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!
pause

May I but in ?  OK, I will anyway.
Before you get too far, look this over.

MS-DOS System Date Cannot Have a Year Past 2099
Article ID: 58495 - Last Review: May 10, 2003 - Revision: 2.0
http://support.microsoft.com/kb/58495

It apples to Microsoft MS-DOS 6.22 Standard Edition, so if you really use DOS and not the XP command prompt, you can have a problem.
 Maybe. I don't know. 

[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!
pause

if your date looks like yyyy/mm/dd then change every delims=- to delims=/

[Reno]

you could do all of this in vbscript

Code: [Select]

'lastrun.vbs - check for vbs lastrun and rename a folder if less than 7d
f=".\testfolder"
with createobject("scripting.filesystemobject")
if not .folderexists(f) then wsh.echo f, "not exist":wsh.quit 1

lastrun=now
if .fileexists(".\dummy.txt") then lastrun=.getfile(".\dummy.txt").datelastmodified
wsh.echo "Last run:",lastrun

if datediff("d",now,lastrun)<7 then
d=.getbasename(f) & "_" & right(year(date)*10000+month(date)*100+day(date),6)
wsh.echo "Less than 7 days, rename to", d
.getfolder(f).name = d
end if

set dummy=.opentextfile(".\dummy.txt",2,true)
dummy.writeline now
dummy.close
end withto run, type at command prompt "lastrun.vbs"
use cscript engine: cscript//nologo lastrun.vbs
use wscript engine: wscript//nologo lastrun.vbs

or if you insist on batch code, i've the pure batch code which is twice the size of vbs code.
or you could have the best of both world with the above code by devcom

Thanks everyone for all your help.

I'm gonna go away ant try these out.

no doubt, i'll be back if i get confused 

[TheSpecial1]

Hi - back again 

I am almost there, however there is one small problem.

The script successfully renames the test folder, however when i run it again it should do the comparison to see when it was last run. It was run less than 7 days ago the 'rename will not be performed' message should display.

The script for some reason is not doing this. When i run it for the second time I get the 'duplicate file name exists or location cannot be found' error instead.

I think it is because of the "if not" statement that compares the 2 dates to see whether 7 days have elapsed.
The 2 variables are in different formats and therefore the statement fall over.
i.e.
Date  = 28/04/09
Date7 - 05052009

Am I correct in this? and how to I get the date.txt  in the same format as the date7 variable?

thanks

[devcom]

forgot to told this to you

you also need to change this:

Code: [Select]

if not %date:+=% GEQ %date7:+=% (
to

Code: [Select]

if not %date:/=% GEQ %date7:/=% (
so it can remove it

and i don't know why Date & Date7 are in different format... they should be the same as it uses the same command

[TheSpecial1]

Hi,

I'm almost there - so the batch file runs and successfully renames the test folder to test_yyyymmdd

If I create another test folder and run the batch file again - it should check if the batch file has been run in the last 7 days and then decide wether to run or not.

So in the case of me creating the second test folder, the batch file should not run as i have previosuly run it on the same day.

I have tried this and it is not working 

I get the following error -  "A duplicate file name exists, or the file cannot be found"

What am I doing wrong?   

Code: [Select]

@echo off

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

for /f "tokens=1-3 delims=/" %%A in ('cscript //nologo evaluate.vbs date') do set current=%%A%%B%%C
if not exist date.txt echo.%current% >date.txt

set /p date=<date.txt

for /f "tokens=1-3 delims=/" %%A in ('cscript //nologo evaluate.vbs date+7') do set date7=%%A%%B%%C

if not %date:/=% GEQ %date7:/=% (
echo Rename will not be performed.
pause >nul
exit
)

ren %org% %org%_%yymmdd%
echo.%current% >date.txt

echo. DONE!
pause


[devcom]

final code i think

edit: or no...

edit: if i understand you good add this in front of file:

Code: [Select]

for /f "tokens=*" %%a in ('dir /b ^|findstr "%org%"') do (
if not "%%a" equ "%org%"(
echo Error: %%a
pause >nul
exit
)
)
