Shell Programming and Scripting

I find my pre-post is the wrong place ,so place it here
I have three question about find

1)regardless if it can "find" something or not, the "find" will return 0,how can we use "if" to judge not find or find?

for example
#find bin/ -name bla.c
1)find it will return 0
2) not found it will return 0

the question is how can I use "if" in the bash to judge it find or not

2)can we find in something specific directory(bin,/usr/bin)

eg:I want find the bla.c only in the "bin" and "/usr/bin"

3)can we find something not in some directory(bin,/usr/bin)

eg:I want find the bla.c not in the "bin" and "/usr/bin"

That's not the way it works. You have a thread already open with the questions so continue in it, thanks.
