The compilation, plus my own code that follows, took well over 12 hours of work in research, tests, & getting this together.

My Request? One or more of:
-> A general "find & replace"  to rename files in a folder: the MS-DOS code must replace a specified string in any part of  a name with another specified string (which may be null or other). You can use the info below to help out.  Anyone up for the  challenge?

-> Failing that, then points  to any rename routine that's uniquely functional and worthy of being added to this collection.  (& If solution also works in Win98, Joy! :))

-> Still nothing? Then points to whoever locates free internet documentation of the ":~4%" feature as used in a rename command. (see "Please let me know" under 'Remove a prefix' below) .

N o t e s :
- Some code I've condensed using the '&' sign (for NT/2k/XP) or the '|' sign (for 98) which often allow use of multiple commands on one line. See http://computerhope.com/issues/ch000177.htm "Can you type more than one command at one command prompt?". (Some of what fails:  '|' after 'if' or 'call' statement; '&'  after 'if', '&' after 'set' as in:set x=y&if  %x%==y echo y; the set doesn't happen until AFTER a line break! Weird language...) Note: to echo the '&'  you must 'echo ^&'
-The code-author's EE id usually follows each code block.
-Some code  just 'echo's the rename commands to be run. Must remove the 'echo' from 'echo ren' to actually do the deed.

~~ Add a suffix (*_n): ~~
FOR %%f IN (*.*) DO ren %%f %%f_n

~~ Remove a suffix (Remove b in   a_b.c) ~~
@echo off&for %%f in (*_*.*) do call :ProcessFile %%f
goto :eof
for /F "delims=_. tokens=1,3" %%c in ("%1") do echo ren "%1" "%%c.%%d"

~~ Add a prefix (S1*): ~~
for %%i in (*.*) do move %%i s1%%i  
for /f "delims=" %i in ('dir/b') do ren "%i" "s1%i"

The DOS command shell, to include WinNT/2K/XP has always acted strangely when using wildcards in the middle of filenames. The truth is, that wildcards almost never work correctly when the wildcard is in the middle of the filename.
For example:
"REN *.TXT *-S1.TXT" will result in the file TEST1.TXT being renamed to TEST1.TXT-S1.TXT
"REN *.TXT S1-*.TXT" will result in the file TEST1.TXT being renamed to S1-T1.TXT

~~ Remove a prefix -- a fixed # of bytes. Replace with new prefix. (SFyymmddhhmm.csv->SISCR12mmddhhmm.csv ) ~~
*** ":~4%" crop feature: where is it documented? Please let me know... - callrs***

~~ Add a prefix to numbers-only file-name: ~~

Looking at the code you posted here, I assume that "using pure DOS" means avoiding the use of external utilities, and that a Windows 2000 / XP command prompt is fine.  The following  code will prompt for "search" and "replacement" text, and echo the rename command for files in the current directory:

@echo off

set /p Srch=Text in filename to find:
set /p Repl=Text to replace "%Srch%" with:
echo Searching for filenames containing "%Srch%" and replacing with "%Repl%" ...
for /f "tokens=*" %%a in ('dir /b *%Srch%*') do call :Replace "%%a"      
goto :EOF

set x=%1
call set x=%%x:%Srch%=%Repl%%%
echo ren %1 %x%

As for the "free internet documentation of the ":~4%" feature", I couldn't find anything, but a brief description from my own experience is:
Using the environment variable ENV (as in set ENV=SomeTestText)
echo %ENV:~4%
would take the text in %ENV%, and echo starting at the 4th character to the end
echo %ENV:~4,2%
would take the text in %ENV%, and echo starting at the 4th character and outputting just 2 characters
echo %ENV:~-4,2%
would take the text in %ENV%, and echo starting at the 4th character from the end (because of the -) and outputting just 2 characters

Nice compilation of batch code.  I hope my input helps answer your most recent question.

Could try this for NT2000+:

@echo off

setlocal enabledelayedexpansion

set fromMask=%~1
set toMask=%~2

if [%fromMask%]==[] echo Usage %0 fromMask [toMask]&goto :EOF

for /f "delims=" %%a in ('dir /b /a-d *.* 2^>NUL') do call :PROCESS "%%a"

goto :EOF


set nameOnly=%~n1
set nameOnly=!nameOnly:%fromMask%=%toMask%!

if "%nameOnly%"=="" goto :EOF
if /i "%nameOnly%"=="%~n1" goto :EOF

echo ren %1 "%nameOnly%%~x1"

Note, I've disabled the rename for testing.

Good Luck,

Mohsan, looks like a very nice tutorial, thank you.

But here's a tip: A link etc. is all-important to identify the source, and pasting some relevant material from the article can be better than copying in the whole thing.    ;)
And when the same entire long info is pasted across multiple threads, it needlessly balloons the forum; also, the author of the article may mind.

(Side note, of concern, not to bash: "start behaving as an adult" --> comment insults & is presumptuous of kids, who start off naturally loving giving inquisitive and faithful, and whom adults can learn mountains of wisdom from...adults not kids have made the pains we see in the world...)

In the spirit of helping upon which I embarked on this task -- spending, less for myself than for the world, not the stated 12 but double that time to find, categorize, test, edit, and fully credit a kaleidoscope of DOS rename routines --  I had hoped to spend several more hours to enhance the investment here before closing. In all honesty, question was asked not to ask it, but to find a way, in first days here at ee, to present the research to the programming community. But as this was something I 'selfishly' sought, I then got lost in solving others' multitude of issues at ee; a habit even in my own life of looking after others first: I often do for others what's delayed indefinitely for myself.

Computer's been my escape from hardships: recent major dental pain, looming critical housing crisis, renovation-company nightmare, malnutrition, neighborhood slander, people seeing my lack & harshly critiquing "you don't work", etc. Computer is where I can shut out practical and social stigmas and just go code or advise or help others...and I've done this for years free of charge even before ee, with countless expressions of thanks received.

No AnnieMod, I don't think the experts just love to lose their time; who does, least of all I who sees every moment as precious to be spent productively with a smile. I was simply buying time in a changed comic-relief sort of way despite what had happened that very month that has literally knocked me out since the 8th from an act of extreme insensitivity at ee, turning the computer screen -- a vital refuge -- into the very trap I sought escape from, with repercussions that have cost me and others great anguish and loss.

But closing thread as requested.

Sorry for the delay. I'd embarked on a multi-purpose file rename utility to post here (program to find and replace: prefix, suffix, middle, extension,...) the day of GuruGary's answer, but never finished the tests; right now however mental acuity is lacking to be able to complete it while other commitments await.


Mohsan, thanks for the apology & the commitment to the future. Hope you learn more MS-DOS as well : )
