RE: grep-find question (Is it a bug of GunWin32 version of "grep")

Hi Eli,

Where did you download the package? I downgraded it from
http://gnuwin32.sourceforge.net/packages/grep.htm.

I have uninstall and re-install it, but the problem still exists. And
I also try the ZIP package, the result is the same. And I cannot find
pcre.dll in these packages. Only pcre3.dll there.

My pcre3.dll is shipped with SETUP package and ZIP package. The
timestamp is as follows:

Actually, I mean it has problem when the text string in the file is
uppercase. In my example, I have a text string "RS17" in file
"MyBase.muse". When I use "-i rs17" or "-i RS17" to search, I cannot
find "RS17" in that file. But I also have another text string "rs17"
in file "MyBase.muse", and I use "-i rs17" or "-i RS17" and I can find
it ("rs17" in the file) successfully. Very strange.


Regards,
Brian

Strange.  I installed Grep from a zip file, not with a self-installing setup program, and I clearly see only pcre.dll in the grep-2.5.1a-dep.zip archive I still have on my machine.

What is the time stamp of pcre3.dll on your system?

Also, does it help to reinstall Grep?

Yes, I've tried that, and it works as I expect: it finds text case-insensitively no matter if I specify the search string in uppercase or lowercase.

FWIW, I don't recommend this.  MSYS ports are meant for one purpose
only: to be able to build MinGW ports of other tools.  For that purpose, they sometimes tweak the command-line arguments in order to allow running those commands from Unix shell scripts.  In particular, they convert Windows file names with drive letters into pseudo-Posix file names that start with a forward slash.  If a command-line argument looks like a file name, but really isn't, this conversion could have devastating effect on the Grep command.
