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? > And I found if when text in the file is lowcase, e.g., "rs17", then I can use "-i" option to find it successfully. e.g., "-i RS17". > But if the text in the file is uppercase, e.g., "RS17", then neither "-i rs17" nor "-i RS17" can found it :( See below: > (Have you tried that?) 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. > I currently use the MSYS version for my Emacs and it works well. 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.
