I have 324 files on a Windows 10 machine which are named in the following pattern:
[7 Numbers] [Space] [Last name] [Space] [First name]
And I need them to be:
[Last name] [Space] [First name] [Space] [7 Numbers]
I have done some quick research and found that I could write a batch script utilizing the 'rename' function:
#echo off
rename “y:\*.txt” “???-Test1.*”
However, I was unable to find out how I can program the script to take the first 7 chracters and put them to the end.
Any help is appreciated.
Given the little detail on the exact formatting of your structures, i.e what happens in the event a surname has a split like van Halen which also now contains a space:
anyway, this will cater for the situation as you've mentioned only and not for names/surnames containing spaces.
#echo off
for /f "tokens=1-3*" %%i in ('dir /b /a-d *.txt ^| findstr /R "^[1-9]"') do echo ren "%%i %%j %%k" "%%~nk %%~nj %%~ni%%~xk"
Note this example will simply echo the command and not perform the actual rename. You need to test it first before you do the renaming. Once you are happy with the result printed to console, then remove echo from the line.
Note. findstr is important here as we need to only perform the action if the file starts with numbers. You can define the findstr filter even more if you want to be more specific. Here I just focused on numbers in the beginning of any .txt file considering no name or surname should start with a number., Unless you're 50cent or some other random rapper.
#ECHO OFF
SETLOCAL ENABLEDELAYEDEXPANSION
rem The following setting for the source directoryis a name
rem that I use for testing and deliberately includes spaces to make sure
rem that the process works using such names. These will need to be changed to suit your situation.
SET "sourcedir=u:\your files\t w o"
FOR %%b IN ("%sourcedir%\??????? * *.txt") DO FOR /f "tokens=1*delims= " %%u IN ("%%~nb") DO SET /a junk=0&SET /a "junk=1%%u" 2>nul&IF !junk! geq 10000000 IF !junk! leq 19999999 ECHO REN "%%b" "%%v %%u.txt"
GOTO :EOF
Please note that this routine uses delayedexpansion
The first for puts the absolute filename of each file matching the mask into %%b
The second partitions the name part of the filename (%%~nb) into that part before the first space (token 1) to %%u and the remainder (token *) to %%v
junk is then set to 0 and then reset to the value of 1%%u. set /a will leave junk unchanged (therefore, 0) if %%u is not a numeric string (the 2>nul suppresses the error message) so if %%u is numeric, junk will be set to 10000000 ... 19999999.
Use !junk! to access the run-time value of junk, check it is within range and if so, echo the ren required.
Remove the echo keyword before the ren after checking the resultant report to actually rename the files.
I am compressing files using WinZip on the command line. Since we archive on a daily basis, I am trying to add date and time to these files so that a new one is auto generated every time.
I use the following to generate a file name. Copy paste it to your command line and you should see a filename with a Date and Time component.
echo Archive_%date:~-4,4%%date:~-10,2%%date:~-7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.zip
Output
Archive_20111011_ 93609.zip
However, my issue is AM vs PM. The AM time stamp gives me time 9 (with a leading blank space) vs. 10 naturally taking up the two spaces.
I guess my issue will extend to the first nine days, first 9 months, etc. as well.
How do I fix this so that leading zeroes are included instead of leading blank spaces so I get Archive_20111011_093609.zip?
Another solution:
for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set datetime=%%I
It will give you (independent of locale settings!):
20130802203023.304000+120
( YYYYMMDDhhmmss.<milliseconds><always 000>+/-<minutes difference to UTC> )
From here, it is easy:
set datetime=%datetime:~0,8%-%datetime:~8,6%
20130802-203023
For Logan's request for the same outputformat for the "date-time modified" of a file:
for %%F in (test.txt) do set file=%%~fF
for /f "tokens=2 delims==" %%I in ('wmic datafile where name^="%file:\=\\%" get lastmodified /format:list') do set datetime=%%I
echo %datetime%
It is a bit more complicated, because it works only with full paths, wmic expects the backslashes to be doubled and the = has to be escaped (the first one. The second one is protected by surrounding quotes).
Extract the hour, look for a leading space, if found replace with a zero;
set hr=%time:~0,2%
if "%hr:~0,1%" equ " " set hr=0%hr:~1,1%
echo Archive_%date:~-4,4%%date:~-10,2%%date:~-7,2%_%hr%%time:~3,2%%time:~6,2%.zip
You should search; you can simply replace all spaces with zero set hr=%hr: =0% – jeb Oct 11 '11 at 14:16
So I did:
set hr=%time:~0,2%
set hr=%hr: =0%
Then use %hr% inside whatever string you are formatting to always get a two-digit hour.
(Jeb's comment under the most popular answer worked the best for me and is the simplest. I repost it here to make it more obvious for future users.)
As Vicky already pointed out, %DATE% and %TIME% return the current date and time using the short date and time formats that are fully (endlessly) customizable.
One user may configure its system to return Fri040811 08.03PM while another user may choose 08/04/2011 20:30.
It's a complete nightmare for a BAT programmer.
Changing the format to a firm format may fix the problem, provided you restore back the previous format before leaving the BAT file. But it may be subject to nasty race conditions and complicate recovery in cancelled BAT files.
Fortunately, there is an alternative.
You may use WMIC, instead. WMIC Path Win32_LocalTime Get Day,Hour,Minute,Month,Second,Year /Format:table returns the date and time in a invariable way. Very convenient to directly parse it with a FOR /F command.
So, putting the pieces together, try this as a starting point...
SETLOCAL enabledelayedexpansion
FOR /F "skip=1 tokens=1-6" %%A IN ('WMIC Path Win32_LocalTime Get Day^,Hour^,Minute^,Month^,Second^,Year /Format:table') DO (
SET /A FD=%%F*1000000+%%D*100+%%A
SET /A FT=10000+%%B*100+%%C
SET FT=!FT:~-4!
ECHO Archive_!FD!_!FT!.zip
)
I found the best solution for me, after reading all your answers:
set t=%date%_%time%
set d=%t:~10,4%%t:~7,2%%t:~4,2%_%t:~15,2%%t:~18,2%%t:~21,2%
echo hello>"Archive_%d%"
If AM I get 20160915_ 150101 (with a leading space and time).
If PM I get 20160915_2150101.
#For /F "tokens=1,2,3,4 delims=/ " %%A in ('Date /t') do #(
Set DayW=%%A
Set Day=%%B
Set Month=%%C
Set Year=%%D
Set All=%%D%%B%%C
)
"C:\Windows\CWBZIP.EXE" "c:\transfer\ziptest%All%.zip" "C:\transfer\MB5L.txt"
This takes MB5L.txt and compresses it to ziptest20120204.zip if run on 4 Feb 2012
You can add leading zeroes to a variable (value up to 99) like this in batch:
IF 1%Var% LSS 100 SET Var=0%Var%
So you'd need to parse your date and time components out into separate variables, treat them all like this, then concatenate them back together to create the file name.
However, your underlying method for parsing date and time is dependent on system locale settings. If you're happy for your code not to be portable to other machines, that's probably fine, but if you expect it to work in different international contexts then you'll need a different approach, for example by reading out the registry settings:
HKEY_CURRENT_USER\Control Panel\International\iDate
HKEY_CURRENT_USER\Control Panel\International\iTime
HKEY_CURRENT_USER\Control Panel\International\iTLZero
(That last one controls whether there is a leading zero on times, but not dates as far as I know).
From the answer above, I have made a ready-to-use function.

As others have already pointed out, the date and time formats of %DATE% and %TIME% (as well as date /T and time /T) are locale-dependent, so extracting the current date and time is always a nightmare, and it is impossible to get a solution that works with all possible formats since there are hardly any format limitations.
But there is another problem with a code like the following one (let us assume a date format like MM/DD/YYYY and a 12 h time format like h:mm:ss.ff ap where ap is either AM or PM and ff are fractional seconds):
rem // Resolve AM/PM time:
set "HOUR=%TIME:~,2%"
if "%TIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%TIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %DATE:~-4,4%%DATE:~0,2%%DATE:~3,2%_%HOUR:~-2%%TIME:~3,2%%TIME:~6,2%
Each instance of %DATE% and %TIME% returns the date or time value present at the time of its expansion, therefore the first %DATE% or %TIME% expression might return a different value than the following ones (you can prove that when echoing a long string containing a huge amount of such, preferrably %TIME%, expressions).
You could improve the aforementioned code to hold a single instance of %DATE% and %TIME% like this:
rem // Store current date and time once in the same line:
set "CURRDATE=%DATE%" & set "CURRTIME=%TIME%"
rem // Resolve AM/PM time:
set "HOUR=%CURRTIME:~,2%"
if "%CURRTIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%CURRTIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %CURRDATE:~-4,4%%CURRDATE:~0,2%%CURRDATE:~3,2%_%HOUR:~-2%%CURRTIME:~3,2%%CURRTIME:~6,2%
But still, the returned values in %DATE% and %TIME% could reflect different days when executed at midnight.
The only way to have the same day in %CURRDATE% and %CURRTIME% is this:
rem // Store current date and time once in the same line:
set "CURRDATE=%DATE%" & set "CURRTIME=%TIME%"
rem // Resolve AM/PM time:
set "HOUR=%CURRTIME:~,2%"
if "%CURRTIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%CURRTIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Fix date/time midnight discrepancy:
if not "%CURRDATE%" == "%DATE%" if %CURRTIME:~0,2% equ 0 set "CURRDATE=%DATE%"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %CURRDATE:~-4,4%%CURRDATE:~0,2%%CURRDATE:~3,2%_%HOUR:~-2%%CURRTIME:~3,2%%CURRTIME:~6,2%
Of course the occurrence of the described problem is quite improbable, but at one point it will happen and cause strange unexplainable failures.
The described problem cannot occur with the approaches based on the wmic command as described in the answer by user Stephan and in the answer by user PA., so I strongly recommend to go for one of them. The only disadvantage of wmic is that it is way slower.
Your question seems to be solved, but ...
I'm not sure if you take the right solution for your problem.
I suppose you try to compress each day the actual project code.
It's possible with ZIP and 1980 this was a good solution, but today you should use a repository system, like subversion or git or ..., but not a zip-file.
Ok, perhaps it could be that I'm wrong.
I realise this is a moot question to the OP, but I just brewed this, and I'm a tad proud of myself for thinking outside the box.
Download gawk for Windows at http://gnuwin32.sourceforge.net/packages/gawk.htm .... Then it's a one liner, without all that clunky DOS batch syntax, where it takes six FOR loops to split the strings (WTF? That's really really BAD MAD AND SAD! ... IMHO of course)
If you already know C, C++, Perl, or Ruby then picking-up AWK (which inherits from the former two, and contributes significantly to the latter two) is a piece of the proverbial CAKE!!!
The DOS Batch command:
echo %DATE% %TIME% && echo %DATE% %TIME% | gawk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}"
Prints:
Tue 04/09/2012 10:40:38.25
20120904-104038
Now that's not quite the full story... I'm just going to be lazy and hard-code the rest of my log-file-name in the printf statement, because it's simple... But if anybody knows how to set a %NOW% variable to AWK's output (yeilding the guts of a "generic" now function) then I'm all ears.
EDIT:
A quick search on Stack Overflow filled in that last piece of the puzzle, Batch equivalent of Bash backticks.
So, these three lines of DOS batch:
echo %DATE% %TIME% | awk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}" >%temp%\now.txt
set /p now=<%temp%\now.txt
echo %now%
Produce:
20120904-114434
So now I can include a datetime in the name of the log-file produced by my SQL Server installation (2005+) script thus:
sqlcmd -S .\SQLEXPRESS -d MyDb -e -i MyTSqlCommands.sql >MyTSqlCommands.sql.%now%.log
And I'm a happy camper again (except life was still SOOOOO much easier on Unix).
I prever to use this over the current accepted answer from Stephan as it makes it possible to configure the timestamp using named parameters after that:
for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x
It will provide the following parameters:
Day
DayOfWeek
Hour
Milliseconds
Minute
Month
Quarter
Second
WeekInMonth
Year
You can then configure your format like so:
SET DATE=%Year%%Month%%Day%
So you want to generate date in format YYYYMMDD_hhmmss.
As %date% and %time% formats are locale dependant you might need more robust ways to get a formatted date.
Here's one option:
#if (#X)==(#Y) #end /*
#cscript //E:JScript //nologo "%~f0"
#exit /b %errorlevel%
#end*/
var todayDate = new Date();
todayDate = "" +
todayDate.getFullYear() +
("0" + (todayDate.getMonth() + 1)).slice(-2) +
("0" + todayDate.getDate()).slice(-2) +
"_" +
("0" + todayDate.getHours()).slice(-2) +
("0" + todayDate.getMinutes()).slice(-2) +
("0" + todayDate.getSeconds()).slice(-2) ;
WScript.Echo(todayDate);
and if you save the script as jsdate.bat you can assign it as a value :
for /f %%a in ('jsdate.bat') do #set "fdate=%%a"
echo %fdate%
or directly from command prompt:
for /f %a in ('jsdate.bat') do #set "fdate=%a"
Or you can use powershell which probably is the way that requires the less code:
for /f %%# in ('powershell Get-Date -Format "yyyyMMdd_HHmmss"') do set "fdate=%%#"
Adding other options to this list of answers.
you could have replaced empty space with a 0 something like echo %time: =0%
but that is still dependent, move that code to a buddy's PC in some other random place and you'll get funny outputs. So you can incorporate powershell's Get-Date:
for /f "tokens=*" %%i in ('PowerShell -Command "Get-Date -format 'yyyymmdd_HHmmss'"') do echo %%i.zip"
A space is legal in file names. If you put your path and file name in quotes, it may just fly. Here's what I'm using in a batch file:
svnadmin hotcopy "C:\SourcePath\Folder" "f:\DestPath\Folder%filename%"
It doesn't matter if there are spaces in %filename%.
#ECHO OFF

You were already reading each line to %%f. Tokenise each line to %%a,%%b,%%c using spaces as delimiters then if the first token is not Comment, see whether the second is name and set a variable named %%a to the value on the remainder of the line after name, %%c.
When the first token is Comment, then output the names that have been detected and clear the variables ready for the next data block.
I do not want to use any scripting language, but just plain command line commands/scripting.
I can solve this using a (prepared) TZ table (e.g. format: UTC+06:00 + 'TZ name'), then use TZUTIL to collect their resp UTC values and calculate the Timezone's local time (preferably taking DST into account).
I am just hoping that somebody already did this in a more "proper" way. Searched this/other sites, but found nothing so far.
ps: no 'external' tools/etc, since the final batch-file needs to be distributed EMEA-wise.
get the local date and time (wmic)
get the local offset (wmic)
convert the local time to UTC with the help of #2
get the offset of a TZ. (tzutil /l)
convert the result of #3 and #4 not to mention the change of date (this is where it gets complicated).
I think I have not forgotten something? :)

As others have already pointed out, the date and time formats of %DATE% and %TIME% (as well as date /T and time /T) are locale-dependent, so extracting the current date and time is always a nightmare, and it is impossible to get a solution that works with all possible formats since there are hardly any format limitations.
But there is another problem with a code like the following one (let us assume a date format like MM/DD/YYYY and a 12 h time format like h:mm:ss.ff ap where ap is either AM or PM and ff are fractional seconds):
rem // Resolve AM/PM time:
set "HOUR=%TIME:~,2%"
if "%TIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%TIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %DATE:~-4,4%%DATE:~0,2%%DATE:~3,2%_%HOUR:~-2%%TIME:~3,2%%TIME:~6,2%
Each instance of %DATE% and %TIME% returns the date or time value present at the time of its expansion, therefore the first %DATE% or %TIME% expression might return a different value than the following ones (you can prove that when echoing a long string containing a huge amount of such, preferrably %TIME%, expressions).
You could improve the aforementioned code to hold a single instance of %DATE% and %TIME% like this:
rem // Store current date and time once in the same line:
set "CURRDATE=%DATE%" & set "CURRTIME=%TIME%"
rem // Resolve AM/PM time:
set "HOUR=%CURRTIME:~,2%"
if "%CURRTIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%CURRTIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %CURRDATE:~-4,4%%CURRDATE:~0,2%%CURRDATE:~3,2%_%HOUR:~-2%%CURRTIME:~3,2%%CURRTIME:~6,2%
But still, the returned values in %DATE% and %TIME% could reflect different days when executed at midnight.
The only way to have the same day in %CURRDATE% and %CURRTIME% is this:
rem // Store current date and time once in the same line:
set "CURRDATE=%DATE%" & set "CURRTIME=%TIME%"
rem // Resolve AM/PM time:
set "HOUR=%CURRTIME:~,2%"
if "%CURRTIME:~-2%" == "PM" if %HOUR% lss 12 set /A "HOUR+=12"
if "%CURRTIME:~-2%" == "AM" if %HOUR% equ 12 set /A "HOUR-=12"
rem // Fix date/time midnight discrepancy:
if not "%CURRDATE%" == "%DATE%" if %CURRTIME:~0,2% equ 0 set "CURRDATE=%DATE%"
rem // Left-zero-pad hour:
set "HOUR=0%HOUR%"
rem // Build and display date/time string:
echo %CURRDATE:~-4,4%%CURRDATE:~0,2%%CURRDATE:~3,2%_%HOUR:~-2%%CURRTIME:~3,2%%CURRTIME:~6,2%
Of course the occurrence of the described problem is quite improbable, but at one point it will happen and cause strange unexplainable failures.
The described problem cannot occur with the approaches based on the wmic command as described in the answer by user Stephan and in the answer by user PA., so I strongly recommend to go for one of them. The only disadvantage of wmic is that it is way slower.
Your question seems to be solved, but ...
I'm not sure if you take the right solution for your problem.
I suppose you try to compress each day the actual project code.
It's possible with ZIP and 1980 this was a good solution, but today you should use a repository system, like subversion or git or ..., but not a zip-file.
Ok, perhaps it could be that I'm wrong.
I realise this is a moot question to the OP, but I just brewed this, and I'm a tad proud of myself for thinking outside the box.
Download gawk for Windows at http://gnuwin32.sourceforge.net/packages/gawk.htm .... Then it's a one liner, without all that clunky DOS batch syntax, where it takes six FOR loops to split the strings (WTF? That's really really BAD MAD AND SAD! ... IMHO of course)
If you already know C, C++, Perl, or Ruby then picking-up AWK (which inherits from the former two, and contributes significantly to the latter two) is a piece of the proverbial CAKE!!!
The DOS Batch command:
echo %DATE% %TIME% && echo %DATE% %TIME% | gawk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}"
Prints:
Tue 04/09/2012 10:40:38.25
20120904-104038
Now that's not quite the full story... I'm just going to be lazy and hard-code the rest of my log-file-name in the printf statement, because it's simple... But if anybody knows how to set a %NOW% variable to AWK's output (yeilding the guts of a "generic" now function) then I'm all ears.
EDIT:
A quick search on Stack Overflow filled in that last piece of the puzzle, Batch equivalent of Bash backticks.
So, these three lines of DOS batch:
echo %DATE% %TIME% | awk -F"[ /:.]" "{printf(""""%s%02d%02d-%02d%02d%02d\n"""", $4, $3, $2, $5, $6, $7);}" >%temp%\now.txt
set /p now=<%temp%\now.txt
echo %now%
Produce:
20120904-114434
So now I can include a datetime in the name of the log-file produced by my SQL Server installation (2005+) script thus:
sqlcmd -S .\SQLEXPRESS -d MyDb -e -i MyTSqlCommands.sql >MyTSqlCommands.sql.%now%.log
And I'm a happy camper again (except life was still SOOOOO much easier on Unix).
I prever to use this over the current accepted answer from Stephan as it makes it possible to configure the timestamp using named parameters after that:
for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do set %%x
It will provide the following parameters:
Day
DayOfWeek
Hour
Milliseconds
Minute
Month
Quarter
Second
WeekInMonth
Year
You can then configure your format like so:
SET DATE=%Year%%Month%%Day%
So you want to generate date in format YYYYMMDD_hhmmss.
As %date% and %time% formats are locale dependant you might need more robust ways to get a formatted date.
Here's one option:
#if (#X)==(#Y) #end /*
#cscript //E:JScript //nologo "%~f0"
#exit /b %errorlevel%
#end*/
var todayDate = new Date();
todayDate = "" +
todayDate.getFullYear() +
("0" + (todayDate.getMonth() + 1)).slice(-2) +
("0" + todayDate.getDate()).slice(-2) +
"_" +
("0" + todayDate.getHours()).slice(-2) +
("0" + todayDate.getMinutes()).slice(-2) +
("0" + todayDate.getSeconds()).slice(-2) ;
WScript.Echo(todayDate);
and if you save the script as jsdate.bat you can assign it as a value :
for /f %%a in ('jsdate.bat') do #set "fdate=%%a"
echo %fdate%
or directly from command prompt:
for /f %a in ('jsdate.bat') do #set "fdate=%a"
Or you can use powershell which probably is the way that requires the less code:
for /f %%# in ('powershell Get-Date -Format "yyyyMMdd_HHmmss"') do set "fdate=%%#"
Adding other options to this list of answers.
you could have replaced empty space with a 0 something like echo %time: =0%
but that is still dependent, move that code to a buddy's PC in some other random place and you'll get funny outputs. So you can incorporate powershell's Get-Date:
for /f "tokens=*" %%i in ('PowerShell -Command "Get-Date -format 'yyyymmdd_HHmmss'"') do echo %%i.zip"
A space is legal in file names. If you put your path and file name in quotes, it may just fly. Here's what I'm using in a batch file:
svnadmin hotcopy "C:\SourcePath\Folder" "f:\DestPath\Folder%filename%"
It doesn't matter if there are spaces in %filename%.
