Operators build a complex expression from tests and actions. The operators are, in order of decreasing precedence:
( expr )
! expr
-not expr
expr1 expr2
expr1 -a expr2
expr1 -and expr2
expr1 -o expr2
expr1 -or expr2
expr1 , expr2
find
searches the directory tree rooted at each file name by
evaluating the expression from left to right, according to the rules of
precedence, until the outcome is known (the left hand side is false for
`-and', true for `-or'), at which point find
moves on
to the next file name.
There are two other tests that can be useful in complex expressions:
Go to the first, previous, next, last section, table of contents.
