Why my find return not expected?
Code:
root@intel_5500_server:~# find / -name bin -o -name sbin                          
/usr/bin
/usr/lib64/pm-utils/bin
/usr/lib64/rpm/bin
/usr/sbin
/bin
/sbin


root@intel_5500_server:~# which ovs-pki 
/usr/bin/ovs-pki

why below command return nothing 

root@intel_5500_server:~# find / -name bin -o -name sbin -exec ls {} \; |grep ovs-pki

You asked it to find something called "bin" or "sbin", not something containing "bin" or "shin". If the latter was the case it would return everything with "bin" or "sbin" in it, not just "ovs-pki".

You would be better putting the file you wanted in the find command, something like:-
Code:
find / -name "*ovs-pki*"



I hope that this helps. It will find any file that matches the pattern with anything either side. The directory structure is not part of the pattern though, so if you want bin or sbin as part of the path, you may need to:-
Code:
find / -name "*ovs-pki*" | egrep "\/s*bin\/"

The egrep expression "\/s*bin\/" will (I hope) match the string of / followed by zero or more s then bin and finally another /. Of course this will match /sssssssssbin/ too if you have one, but it's close.

Perhaps someone can tweak my expression to say "zero or one letter s"



I hope that this helps,
Robin

ovs-pki is located in /usr/bin/, {} contains /usr/bin/, why ls {} doesn't ouput it ?

my case actually want to output all the cmds in bin/ or sbin/, the really question is why it doesn't output ovs-pki, though it's located in /usr/bin

As I said, {} contains "bin", but it isn't called "bin". If "ovs-pki" was a directory and its contents included a file or directory called "bin", then it "ovs-pki" would show up in the search. That's because it's looking for things you asked it to. It would only report "ovs-pki" if it contained something called "bin" ("bin" being the thing you asked it to find).

That's because when it finds what you asked it to it stops. It doesn't find "bin" and then think to itself "Hmmm. I'll just keep going for a minute" Smilie

Yes, because you used the "ls" option, something peculiarly missing from your original post.
