Which (if run at the same time as the previous example) should result in the log file C:\RCLogs\RCLog-17-Feb-02-113943.39.txt.įor more information on string manipulation of environment variables, check out this link. > echo %DATE:~7,2%-%DATE:~3,3%-%DATE:~,2%-%TIME::=%.logĪs /u/Knxtknight is already running this in a batch file, they should be able to just replace the /log parameter with something like the following (although, of course, they'll probably want to modify it for their own locale): /log+:"C:\RCLogs\RCLog-%DATE:~7,2%-%DATE:~3,3%-%DATE:~,2%-%TIME::=%.txt" So (having adjusted the variables to suit my locale and personal preference in logging name formats), we get: %DATE% = 02-Feb-17 So a %TIME% of "11:33:00.65" becomes "113300.65". I want to copy not just file data but also timestamps of regular files and directories. and 'more' outputs that Logfile to the screen with information as to how many new, and changed files copied. As : is not a valid character for a file name, it is replaced with the character after the = - which, in this case, is nothing. bat file to edit, and customise the folder names of source Xcopy copies from, and destination to where copied to. The final part - %time::=% - is a substitution. If /u/dcprom0's locale is set to ddd-DD-MM-YYYY or ddd-MM-DD-YYYY (which, for me at least, would result in "Thu-02-02-2017" quirk of the date means that for today, at least, it doesn't matter which date format applies) then that would explain why he picks up the date/month ( %date:~4,2% - "02"), then the month/date ( %date:~7,2% - "02"), and the year ( %date:~10,4% - "2017"). %date:~10,4% doesn't work because the content of my %DATE% variable isn't long enough. Okay, so youre using batch in Windows and the XCOPY command. After the first run, check the files and permissions on a few folders to verify that everything has been copied as you expect. But subsequent runs should be much faster because you are only copying files that have been changed since the last robocopy run. So in my environment, %date:~0,2% is the date, %date:~7,2% is the year. Copy from one location to another using batch script based on modified date and also newly added files in source. The first run will copy the bulk of the data. COPY:copyflags :: what to COPY for files (default is /COPY:DAT). EFSRAW :: copy all encrypted files in EFS RAW mode. ZB :: use restartable mode if access denied use Backup mode. If your locale set the date format to 'MMM-DD-YY' (which I believe is standard for places like America), then %DATE:~4,2% would return '02' - today's date. /LEV:n :: only copy the top n LEVels of the source directory tree. For example, on my system, %DATE:~4,2% returns eb, because my locale sets the date format to 'DD-MMM-YY' so the %DATE% environment variable is set to '02-Feb-17'. However, the returned characters can be manipulated by adding a colon and instructions on how to change the output - for example, %ENVNAME:~4,2% will return two characters, starting out the fourth character. In the command line/batch scripts, %ENVNAME% returns the data in the environment variable ENVNAME. To elaborate, for those who are uninitiated in the ways of environment variable manipulation: Robocopy normally overwrites those.:: /XN excludes existing files newer than the copy in the source directory. files without having to invoke the tool multiple times. robocopy c:Sourcepath c:Destpath /E /XC /XN /XO:: /E makes Robocopy recursively copy subdirectories, including empty ones.:: /XC excludes existing files with the same timestamp, but different file sizes. The /MIR switch is the equivalent of /E and the /PURGE switches used together (but with a minor exception).%date:~4,2%-%date:~7,2%-%date:~10,4%-%time::=% Robocopy, or Robust Copy, is a CLI utility that has been available in the. on Windows 7 圆4 Ultimate.īe aware that the /MIR switch mirrors the directory that you are copying from that is, /MIR will also delete files in the destination folder not found in the source folder. There is also another (and I believe deprecated?) switch /TIMFIX which does much the same as /COPY:DT but it doesn't fix the time stamps on folders. Will copy all files and folders and preserve the date & time stamps and file attributes. ROBOCOPY c:\src d:\dest /MIR /COPY:DAT /DCOPY:T Will copy all files and folders and preserve the date and time stamps. ROBOCOPY c:\src d:\dest /MIR /COPY:DT /DCOPY:T (S=Security=NTFS ACLs, O=Owner info, U=aUditing info). (copyflags : D=Data, A=Attributes, T=Timestamps). COPY:copyflag :: what to COPY for files (default is /COPY:DAT). Take a look at the options for the /COPY: and /DCOPY switches.
