grep is always recursive

[Hal Burgiss]

Does anyone know of a setting anywhere in Ubuntu (8.04), that would
cause grep to *always* behave as if it were run as 'grep -r'? My home
system always greps recursively, which is highly annoying. I cannot
find an environment setting or system file to explain this, yet
grepping something simple in my home dir, as an example, returns a
huge list of files, including files in various subdirectories. It
makes no difference whatsoever whether grep is invoked as 'grep' or
'grep -r', the behavior is identical. I have other 8.04 systems that
don't do this, so its quite curious to me. What I want is equivalent
to:

  find -maxdepth 1 -exec grep -H $sometoken {} \;

which is what I have to run now, if I am impatient (typically, yes),
so as to avoid grepping through gigs of image and music files that
live within $HOME subdirs.
