1) /usr/local/bin/find (and anything else within /usr/local) was not installed by the Solaris installer. You would need to go find the admin that installed it and find out what flavor of "find" it is. /usr/bin/find <b>is</b> the Solaris "find".
2) It would be nice to see the output of:
<pre>ls -ld .
for the directory you are trying to run your find against. And whether it is on a local disk or an NFS share.
