Quite simple actually. You just need to write a regex that matches lines to be deleted and use the /R option to reject lines that match and the /XSEQ option to enable substitution of \c for ^ and \q for " The \c is needed due to the pesky doubling of ^ when using CALL call jrepl "\c(?:[\c,]*,){4}(?:...

@echo off call :writeFile >output.txt exit /b :writeFile - All output from this routine will be written to output.txt echo Line 1 echo Line 2 echo etc. exit /b Or, if you already have existingScript.bat that writes your desired output to the console (stdout), then from the console command line: c:\...

You should have no problem removing \r (carriage return) in the middle of a line without the /M option. You can remove all \r that are not part of the standard \r\n end of line with the following: call jrepl "\r" "" /f "file.txt" /o - As each line is read, the \r\n end of line is automatically strip...

I originally forgot to left zero pad the number to 4 digits. I edited my prior post to add the padding

This is trivial with JREN.BAT - a hybrid JScript/batch regular expression renaming utility call jren "^.*" "lpad($n,'0000')+'.jpg'" /j /p "c:\pathToYourFolder" /rfm "^[a-z0-9]+$" It is not much more complicated to use pure batch @echo off setlocal enableDelayedExpansion pushd "c:\pathToYourFolder" f...

Pipe is a regex meta-character that means alternation (basically an OR operator). Like any meta character, you escape it with a backslash. The /XSEQ and /M options aren't needed. So JREPL "\|" "" /f TEST2.txt /o TEST2b.txt The other option is to use the /L literal option, so the search is treated as...

Your original request to preserve the first 3 title lines, and then extract and sort the remaining lines that contain FALSE, can be easily solved with JSORT.BAT , plus a little sideways thinking with your use of FINDSTR. JSORT is a hybrid JScript/batch with a number of useful options: Skip n lines (...

JREN.BAT is a hybrid batch/JScript regular expression file/folder renaming utility. But it also has options that make it useful as a directory listing utility, with the ability to display the total size of all files within a folder (including all subfolders recursively). The following will give the...

Assuming you are dealing with English, it is a simple 2 step process with JREN.BAT - a hybrid batch/JScript regular expression renaming utility. First capitalize the first character of every "word". Then convert all extensions to lower case. jren "([a-zA-Z])([a-zA-Z']*)" "uc($1)+lc($2)" /j jren "\.[...

It is hard to imagine a scenario where a self modifying batch file is the best option. It is almost always simpler have static code with various options built in, and use logic to execute the appropriate code. The only case I can think of where self modifying code might be handy is if the end user d...

For some reason I can't get it to execute properly. When I launch it, it seems to be calling cscript.exe but it hangs there. Any ideas what to do about this? That is the designed behavior - it is waiting for input on stdin. It will continue to wait (seemingly hang) until the stdin is closed. You co...

I'm' going to leave that coding exercise to you. The entire JScript language is at your disposal. You can include newlines in your output with the correct JScript code.

In general, the built in help (JREN /?) does a good job describing the features of JREN. It is up to you to figure out how to use those features. Plus there are examples throughout this thread. I hope you take the time to scan all the posts. What code would tell JREN.bat version 2.8 to: 1. count Fil...

The /FM must be the name of the folder or file you want, and the /P must be the full path leading up to that file/folder. for %%F in ("%~dp0.") do call jren "^" "size()+' '" /d /j /list /p "%%~dpF" /fm "%%~nxF" > "FolderList1.txt" "%~dp0." expands to "D:\portable\.", which is logically equivalent to...

Question 1 I'm not exactly sure what you are trying to do. If you want only the size of a single folder, like "D:\portable", then specify the root path with /P and specify the specific folder with /FM call jren "^" "size()+' '" /d /j /list /p "d:\" /fm "portable" Note that size() does not need an a...
