![]() new extension to the original name, so "original.txt" becomes ""īelow is highly optimized code that addresses all but the first 4 points above. I prefer to have my temp file name to be a derivative of the original name. Best to minimize use of CALL if you want the fastest possible solution. The DEL/RENAME pair can be replaced by a single MOVE commandĬALL is relatively slow. Better (faster) to redirect once outside the loop. Redirection is performed for each line of output, which is slow. The only safe variant that is guaranteed to work is ECHO(.Ī non empty line could become empty after replacement if the replacement string is empty, and the empty line will not be output properly because neither ECHO. ![]() This can be simplified by getting the desired strings in environment variables (which may still require escape sequences) and then using delayed expansion and FOR /F to transfer the values to FOR variables. This can be avoided by transferring the search and replacement terms to FOR variables.Ĭertain characters within the search and/or replacement terms could cause problems or require complex escape sequences. The replacement will be corrupted if the search term contains %%a or %%b or %%A. Leading : will be stripped from all lines because consecutive delimiter characters are treated as a single delimiter. This can be solved by strategically toggling delayed expansion on and off within the loop(s). Lines containing ! will be corrupted because delayed expansion is enabled when %%A is expanded. The search string cannot contain = or begin with ~, * or ! Input and output lines must be a bit less than 8191 bytes long. SET modified=!string:%SEARCHTEXT%=%REPLACETEXT%!īut there are many limitations and inefficiencies with the code, with lots of room for improvement. Pushd "c:\path\to\your\folder\containing\files\to\modify"įor %%F in (*.txt) do call :replace "%%F"įor /f "tokens=1,* delims=¶" %%A in ( '"findstr /n ^^ %INTEXTFILE%"') do (įor /f "delims=: tokens=1,*" %%a in ("!string!") do set "string=%%b" Note - I eliminated dead (unused) variables from the code. This can be solved by using FOR /F with the DIR /B command instead. But if your code creates or renames folders, then a FOR loop could also process the newly created or renamed files. The end result of your code does not create or rename any folders, so a simple FOR is safe to use. This is a general approach that can be used for any code that you want to run iteratively HaoZip comes with some additional functions which allow you to view and convert image files, calculate MD5 checksums, batch-rename items and batch-replace strings, scan files for Trojans and open virtual CDs.įrom the 'Settings' section you can select the compression andĭecompression mode (smart or full-speed mode), integrate HaoZip into shell and make it stay on top of other apps, set archive associations,Ĭustomize the appearance, as well as specify the default text and image viewer, just to name a few.If you want a pure batch solution, then the simplest thing to do is to encapsulate the code in a subroutine that takes the name of the file as an argument, and call that routine from within a FOR loop that iterates the file names. ![]() Plus, you can disable the double-panel, convert archives to SFX, view a log file, import and export settings, repair archives, change the interface language and organize profiles. Other features HaoZip revolve around archive encryption, fileĮxclusions, the compression algorithm, time and comments. delete files afterĪrchiving, test archived items, turn off the computer on completion, Size, and configure archiving options (e.g. add and replaceįiles, synchronize archive contents), split the archive to volumes by ZIP, 7Z, TAR, WIM, LZH) and compression method (ranging from 'Store' to 'Best').įurthermore, you can select the update mode (e.g. Creating an archive can be seamlessly done by specifying a name, format (e.g. ![]()
