grep -r *.java doesn't work as expected

[Randall R Schulz]

Wai-Yip,

Grep _will_ search in files found throughout a directory hierarchy, but 
that's not it's default mode of operation. Look into the "-R" / "-r" / 
"--recursive" option and the associated "--include" and "--exclude" options.

Also, I don't know what you intend by your use of "-m", but according to 
the help output, it requires a numeric argument that limits the number of 
matches displayed per target file.

I suspect that in part you're accustomed to a non-Gnu grep program, and 
there are considerable differences between other greps and Gnu grep. Read 
the man page so you'll know how to use it properly.
