Question

I’m automating some source control software functionality using a dot bat script but given that our svn repos are hosted in a *NIX box, I’m facing the eternal case problem between these two worlds.

Is there any cmd.exe function to convert the value of the Windows system variable %USERNAME% to lower case?

Thanks much in advance!

a quick google found this…

@echo off goto :end_remarks ************************************************************************************* * * *    authored:Sam Wofford *    Returns lowercase of a string *    12:13 PM 11/13/02 ************************************************************************************** :end_remarks setlocal set errorlevel=-1 if {%1}=={} echo NO ARG GIVEN&call :Help &goto :endit if {%1}=={/?} call :Help &goto :endit call :set_LCASE_array a b c d e f g h i j k l m n o p q r s t u v w x y z  :start set input=%1 set input=%input:'=% set totparams=0 call :COUNT_PARAMS %input% call :MAKE_LOWERCASE %input% set errorlevel= echo %convertedstring% endlocal goto :eof :endit echo %errorlevel% endlocal goto :eof  :MAKE_LOWERCASE :nextstring if {%1}=={} goto :eof set string=%1 set /a params+=1 set STRINGCONVERTED= set pos=0 :NEXT_CHAR set onechar=%%string^:^~%pos%,1%% for /f 'tokens=1,2 delims==' %%a in ('set onechar') do for /f %%c in ('echo %%b') do call :checkit %%c if not defined STRINGCONVERTED goto :NEXT_CHAR shift /1 if %params% LSS %totparams% set convertedstring=%convertedstring% &:add one space,but not at end goto :nextstring goto :eof  :Help echo USAGE:%~n0 string OR %~n0 'with spaces' echo function returns the lowercase of the string or -1 (error) echo strings with embedded spaces needs to be in quotes Ex. 'lower case' echo in a batch NTscript 'for /f %%%%A in ('lcase STRING') do set var=%%%%A' set errorlevel= goto :eof  :checkit set LCFOUND= if /i {%1}=={echo} set STRINGCONVERTED=Y&goto :eof set char=%1 for /f 'tokens=2 delims=_=' %%A in ('set LCASE_') do call :findit %%A %char% :skipit if defined LCFOUND (set convertedstring=%convertedstring%%ucletter%) else (set convertedstring=%convertedstring%%char%) set /a pos+=1 goto :eof  :set_LCASE_array :setit if {%1}=={} goto :eof set LCASE_%1_=%1 SHIFT /1 goto :setit  :findit if defined LCFOUND goto :eof set ucletter=%1 set lcchar=%2 if /i {%ucletter%}=={%lcchar%} set LCFOUND=yes goto :eof  :COUNT_PARAMS :COUNTPARAMS if {%1}=={} goto :eof set /a totparams+=1 shift /1 goto :COUNTPARAMS  

add that as a file (lowercase.cmd) to your path and you should be able to call it as ‘Lowercase.cmd %Username%’, you could pipe it into another command if needed.
