Sometimes you work on some files within a directory and want to do a backup from time to time. Of course, if you have a version control system like git or svn by hand, you might use this. But if you have no versioning tool, a simple technique often used is to copy all files to an archive folder in the current directory and append a version string to the filename. If you do this a few times after another, you might want to write a small batch script, that does this stupid job for you.
Today I found myself in this situation, thus I started writing a small batch script that copies all files except the batch file itself to the an archiv folder, appending a timestamp to the filename:
set archivefoldername=Archiv set hour=%time:~0,2% if "%hour:~0,1%" == " " set hour=0%hour:~1,1% echo hour=%hour% set min=%time:~3,2% if "%min:~0,1%" == " " set min=0%min:~1,1% echo min=%min% set secs=%time:~6,2% if "%secs:~0,1%" == " " set secs=0%secs:~1,1% echo secs=%secs% set year=%date:~-4% echo year=%year% set month=%date:~3,2% if "%month:~0,1%" == " " set month=0%month:~1,1% echo month=%month% set day=%date:~0,2% if "%day:~0,1%" == " " set day=0%day:~1,1% echo day=%day% set datetimef=%year%-%month%-%day%_%hour%%min%%secs% if not exist %archivefoldername% mkdir %archivefoldername% for %%i in (*) do ( if not %~n0 == %%~ni ( copy %%i %archivefoldername%\%%~ni_%datetimef%%%~xi ) )
