How to exclude directories with find

To exclude directories with find,grep is the obvious choice  but it is not efficient.Following shows three ways to exclude directories with find

#Sample directories and file, the aim is to exclude directory /tmp/test/test1

$find /tmp/test
/tmp/test
/tmp/test/test1
/tmp/test/test1/test1.file
/tmp/test/test2
/tmp/test/test2/test2.file
/tmp/test/test3

(1) Simple most efficient way, but I can only get it working in ksh

$find /tmp/test/!(test1) -type f
/tmp/test/test2/test2.file
/tmp/test/test3

(2)With not expression “! “

$find /tmp/test ! -path "/tmp/test/test1*" -type f
/tmp/test/test2/test2.file
/tmp/test/test3

(3)With prune, which means exclude preceding path

$find /tmp/test  -path  /tmp/test/test1 -prune  -o -type f -print
/tmp/test/test2/test2.file
/tmp/test/test3
