RE: [Condor-users] Command Case Sensitivity on Windows

["Bryan S. Maher" <Bryan.Maher@xxxxxxxxxx>]

Ian,

CONDOR_STATUS works for me in mixed case, but CONDOR_RECONFIG does not. It's my assumption that some commands, like CONDOR_RECONFIG actually call CONDOR.EXE using some command line parsing.  As a result, they pass the uppercase version of themselves to the CONDOR.EXE binary.  

I also understand that arguments are interpreted by the binary.  While they CAN be case sensitive, it is atypical behavior on Windows.  So I was only including it for the sake of completeness.

I believe I first noticed this behavior on Condor 6.6.5 but all my machines currently run 6.6.10.  The behavior is exhibited on Windows XP Professional with SP2 although I first noticed it on SP1.

No, I hadn't because they are not case-sensitive. Calling binaries is an OS thing, not a condor thing. I can call my condor binaries with mixed case, or all one case without any problems on my XP Pro machines:

D:\5.0\sp1\quartus>CONDOR_STATUS

In the case of an command line argument to the binary, case sensitivity is to be expected as interpreting command line arguments is left to the binary and however it was coded by the Condor team. In this case they've opted for case-sensitive options (so that -c and -C can be different commands). But binary calling semantics are handled by the OS (and the shell as well, which in Windows is cmd.exe).

Which Windows version are you using? Which version of cmd.exe are you using as your shell on Windows? Maybe that has something to do with it. I don't run Win2003 but perhaps that has case-sensitive file improvements in it that XP did not...
