This, of course, results in commands responding as if you typed nothing
where a wildcard doesn't match. So
ls -l *.o
results in a directory listing instead of a slightly more helpful
ls: *.o: No such file or directory
Or
cat *.c|grep func_name
waiting on stdin for you. Which is probably worse than the wildcard crap
lying around.
zsh has a "setopt NOMATCH" which prevents the command from running at all in
this case:
cat *.c|grep func_name
zsh: no matches found: *.c
but this has the annoying effect of
find src -name *.h
never working like you want (since if there are .h files, they are expanded.
If there aren't, it refuses to run). And
ls *.c *.h *.o
fails unless you have all three. And if I knew what was there, I wouldn't be
listing for them.
