![]() ![]() I might have gotten a virus, or an app update went belly up. I'm trying to get an idea of 'what changed' that might have triggered this. OldNewThing - Combining ForFiles and FOR.įOR - Conditionally perform a command several times.Įquivalent PowerShell: ForEach-Object - Loop for each object in the pipeline.Įquivalent bash command (Linux): find - Search for files that meet a desired criteria. 10 My PC has entered an infinite BSOD loop - but I do have access to a safe-mode command prompt. Rule #2: It's all small stuff - Dr Robert S Eliot, University of Nebraska cardiologist Related commands xlsx files that were last modified 30 days ago or older:Ĭ:\> FORFILES /M *.xlsx /C "cmd /c echo was changed 30 days ago" /D -30Ĭ:\> FORFILES /S /M *.doc /C "cmd /c echo a command against each text file newer than 1st Jan 2001:Ĭ:\> FORFILES /D + /m *.txt /C "CMD /c echo is new since Jan 1st 2001" If ForFiles finds no matches if will return Errorlevel =1 and will print "ERROR: No files found with the specified search criteria." Examplesĭelete the testfile if it is is 5 days old or older:Ĭ:\> forfiles /m testfile.txt /c "cmd /c Del testfile.txt " /d -5įind all. If ForFiles finds one or more matches if will return Errorlevel =0 In most cases using a simple FOR command along with Parameter extensions will provide a better/less buggy solution. Also any variable created with SET will be lost as soon as FORFILES moves on to the next file. There are some disadvantages to using CMD.exe with FORFILES, a new process will be created and destroyed for every file that FORFILES processes, so if you loop through 1000 files, then 1000 copies of CMD.exe will be opened and closed, this will affect performance. If you want to use an internal commmand, or if you want to use redirection, pipe, command concatenation, etc, then you must use CMD /C. ![]() One workaround for this is to include the program name as the first argument, this will be passed along by FORFILES and the CreateProcess call will then work as expected:Īlternatively pass the command to CMD /C, which will then process all the arguments correctly. FORFILES version 1.46 (24th March 2006) do not suffer from this bug. The expected convention is that argv will contain the program name, but FORFILES instead passes the first argument as argv. Recent versions of FORFILES contain a bug, in processing command line arguments: running a /c command that contains an argument such as FORFILES /C "PING -a" will fail. (still supported for backwards compatibility) also the /D option accepted dates only in DDMMYYYYHHMN format. due to daylight savings time.Įarly versions of FORFILES were supplied in the NT resource kit and used unix style '-' parameters, Last modified dates set in the future are not common but can happen when your computer clock date/time is changed e.g. Last modified time is taken to be midnight 00:00, so FORFILES /D + TodaysDate will find files created today. Internal CMD.exe commands should be preceded with "cmd /c". To include special characters in the command line, use the hexadecimal code for the character in 0xHH format (ex. "+" is taken as the default sign if not specified.Ĭommand The name of the The file name without Only the extension of the Full path of the Relative path of the Returns "TRUE" if a file type is a directory,Īnd "FALSE" for Size of the file in Last modified date of the Last modified time of the file.

Datademodificação: 10:50 AND Datademodificação: 10:50. This worked in Windows 8.1 SL for me: system.datemodified:(>YYYY-MM-DD HH:MM. I'm from Brazil and "datemodified" equals "datademodificação" in my language but if you want to use English you can always use system.datemodified instead the equivalent in your language. The sugested method did not work for me for some reason in Windows 8.1 SL but after trying for 2 or 3 hours I found something out that worked for me. ![]()
