Re: grep -r doesn't work for me

[Mickey Ferguson]

Bob, thanks for the help.  You are right about the missing directory 
argument.  I missed that earlier.  By supplying ".", it eliminated the 'Not 
enough space' error.  I finally got it to the point where I got it mostly 
working, but I discovered one thing about the port that may be good for the 
unix environment, but doesn't work for Windows:  The filename pattern 
matching is case sensitive.  In other words, if I had a file named 
"MyFile.txt" and I searched for "my*.txt" (without the quotes in both 
cases), it would fail to find it, while if I searched for "My*.txt" it would 
find it.  I understand that in the unix world filenames are case-sensitive, 
but in the Windows world they are not.  Thus, file pattern matching should 
not be case-sensitive for the Windows implementation.
