![]() The redirection operators > and | must be escaped with caret character ^ on FOR command line to be interpreted as literal characters when Windows command interpreter processes this command line before executing command FOR which executes the embedded command line with using a separate command process started in background. Read the Microsoft documentation about Using command redirection operators for an explanation of 2>nul and |. There cannot be two files with same name in same directory.įor understanding the used commands and how they work, open a command prompt window, execute there the following commands, and read entirely all help pages displayed for each command very carefully. Note: The command REN outputs an error message if the current directory contains the two files photo (1).jpg and photo (2).jpg on renaming the second file to photo.jpg because of this is not possible after first file already renamed to photo.jpg. That code works also for image file names containing one or more exclamation marks and one or more round brackets before the last four characters in file name to remove. ![]() Hence the process entails adding files or folders to rename at once, select the needed changes of your files, apply changes for all, see the preview, and enjoy the results. Ren "!FileName!%%~xI" "!FileName:~0,-4!%%~xI" You just have to perform 3 steps in order to restructure PC data and rename files in a bulk. Setlocal EnableExtensions DisableDelayedExpansionįor /F "eol=| delims=" %%I in ('dir "* (?).jpg" "* (?).jpeg" /A-D /B /ON 2^>nul ^| %SystemRoot%\System32\findstr.exe /I /R /C:" ()\.jpe*g$"') do ( The file renaming task for all *.jpg and *.jpeg files in the current directory of which file name ends with a space and a single digit number in round brackets can be done with a batch file with following command lines: off Will assign just the name part and you could then set "rec=!rec:~0,-4!%%~xB"Īs to why you get no result at all This could be because the file encoding of %1 is unicode or is *nix format (, not line endings)Īnd I do hope you're not using a *nix emulator like cygwin where find becomes a file-locator, not a string-analyser. Since you seem to want to remove the last 4 characters of the name part and leave the extension, then you need to read the documentation for for ( for /? from the prompt) which will tell you set "rec=%%~nB" rec will thus become img (1).jpg and then be shortened to img (1) by removing the last 4 characters of the string. You don't show us a sample from the file %1, so I'll presume it's img (1).jpg as your narrative mentions. Where you alter your filename, setting rec to %%B means the entire filename, %%B. Quotes are not needed for setting arithmetic values (set /a`) I'd advise you to use set "var1=value" for setting STRING values - this avoids problems caused by trailing spaces. I'm sure this wasn't what you intended to do. ![]() The else clause will only be processed if %%A is 10 or greater, so only on the last line. ![]() The if %%A LSS %lines% will echo %%B (the filename) if %%A (the line number) is LESS ( LSS) than 10 that is, from 1 to 9 - just show the filename. If there are 10 lines for example, then reading the same file again with 'find /v /n` will still find 10 lines. I can see no reason for calculating the number of lines in the file. This differs from your result "it just doesnt do anything". Q71992787.txt, other than the very last filename, which was shortened by 4 characters. The result, other than the debug lines, was a list of the filenames in the file These will need to be changed to suit your situation.įor /f %%A in ('find /V /C "" ^that the process works using such names. Rem The following setting for the source directory includes spaces to make sure Just keep in mind if you have millions files/items as it may take awhile to iterate all of them before any renames are carried out.1/ switched to a test directory (PUSHD testdirectoryname) and back (POPD) Putting $() around a Get-ChildItem ensures that all of the currently existing files get returned first and are then piped into Rename-Item, rather than piped in dynamically without the subexpression operator. Instead of 'dir |' I can use: dir | where-object -filterscript 'dir -recurse' outputs all the files, folders and sub-folders. Notes: 'dir' is an alias of 'Get-ChildItem'. ![]() Using '|' will pipeline the output of 'dir' for the command that follows. You can use 'dir' to see all the files in the folder. Notice: address must incorporate quotes "" if there are spaces involved. Type: "PowerShell" and open the 'Windows PowerShell' command window. ![]()
