I often use grep -r --include. But it has a really annoying problem - the comparison of the filename is case-sensitive. The -i option seems to apply only to the regex not the filename matching.
For example, I have many files named virtualenvironment.ini. But unfortunately, sometimes it is virtualEnvironment.ini, VirtualEnvironment.ini, etc.
Grep -r --include=virtualenvironment.ini skips the latter files. As a work-around, I use --include="[Vv]irtual[Ee]nvironment.ini" but this is cumbersome and not a complete solution.
Because Windows is case-insensitive/case-preserving, I think the Cygwin filename matching should also be case-insensitive. Am I missing something here?
Maybe ... Cygwin is trying to act as closely as possible to Posix behavior as it can when running under Windows. AFAIK, Posix does not offer case-insensitive filename matching for grep. While it's more cumbersome, depending on the filenames you desire to match against, you could do something like: grep your-regex $(find . -iname 'virtualenvironment.ini') The -iname operator of find asks it to do a case-insensitive filename match. See also its -ipath and -iregex operators.
