How it finds it is an implementation detail. There's no need to know how it does what it does if it does what you want. ;-) And, like I said, the registry won't be used for 1.7 so anyone that uses this as a basis of anything will find it broken once 1.7 is released. For that matter, how would a windows .bat file find the 'mount.exe' binary if the .bat file doesn't know 'cygdrive path'? That's a different issue. However you imply a paradox that doesn't exist. Whether one knows the 'cygdrive path' or not will not make it easier to find 'mount.exe'. 'mount.exe' is always in '/bin'. As for the issue of finding '/bin', there may be times when it is necessary to script this, though I would say this is not one of those cases. For those cases, searching the file-system or spelunking in the registry are possible avenues, each with their own pluses and minuses. In this case, just looking at 'cygwin.bat' will provide the answer needed. -- Larry Hall http://www.rfk.com RFK Partners, Inc. (508) 893-9779 - RFK Office 216 Dalton Rd.

Here's how I do it in a little batch file that I put on my USB pen drive: It's in the attached .TXT file - you'll need to rename it to .BAT Note that this batch file will OVERWRITE your fstab so please review it before installing and using it on your system. Basically, it lets me carry Cygwin on a USB stick and it does not care what drive letter it's attached as. Note also that USB sticks are slo, so it's just for emergencies :-) Ralph @ECHO OFF REM -- REM Batch file to start Cygwin on arbitrary drive letters SETLOCAL FOR /F %%D IN (%CD%) DO SET CYGDRIVE=%%~dD REM -- Check if we've already modified the fstab for this drive letter IF %CYGDRIVE%==%CYGWIN_DRIVE% GOTO :DONE REM -- Check if the original fstab has been backed up IF EXIST %CYGDRIVE%\cygwinTest\etc\fstab.original GOTO MAKEFSTAB copy %CYGDRIVE%\cygwinTest\etc\fstab %CYGDRIVE%\cygwinTest\etc\fstab.original REM -- Set up the default fstab :MAKEFSTAB echo # Custom fstab for removable media %CYGDRIVE%\cygwinTest\etc\fstab echo # See /cygwin/etc/fstab.original for defaults %CYGDRIVE%\cygwinTest\etc\fstab echo %CYGDRIVE%/cygwinTest /ntfs binary 0 0 %CYGDRIVE%\cygwinTest\etc\fstab echo %CYGDRIVE%/cygwinTest/bin /usr/bin ntfs binary 0 0 %CYGDRIVE%\cygwinTest\etc\fstab echo %CYGDRIVE%/cygwinTest/lib /usr/lib ntfs binary 0 0 %CYGDRIVE%\cygwinTest\etc\fstab rem -- Start up thedefault shell chdir %CYGDRIVE%\cygwinTest\bin bash --login -i ENDLOCAL :DONE REM We're done with the local variables, but remember to set REM a variable that tells us the drive Cygwin is running on SET CYGWIN_DRIVE=%CYGDRIVE% EXIT /B 0 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
