= This is because csh tries to glob the command name:  if you type
= "f*" and "f*" expands (uniquely) to "foo", then csh will execute
= "foo" without ever looking at your PATH.  ("foo" will get executed
= even if "." isn't in your PATH.)
Try it. csh looks at PATH, even if you use `...` or "*".
"f*" will get expanded, because csh still knows your current
working directory. But when it tries to execute the file foo
it will give : "command not found".
= 
= And the globbing routine also tries backquote substitution.  So
= the globbing succeeds, and csh ignores your PATH.
On my machine the above produces a listing of files in the current
directory.
The reason for the "ls: Command not found" is most probably that
/bin, or wherever ls might be, is not in PATH.
