 ==Expression==
+*Force precedence
   ( expr )
-Force precedence.  Since parentheses are special to the shell, you will normally need to quote them.  Many of the examples in this manual page use backslashes for this purpose:  `\(...\)' instead of `(...)'.
+*négation
   ! expr
-True if expr is false.  This character will also usually need protection from interpretation by the shell.
+  -not expr (not POSIX compliant.)
-  -not expr
-Same as ! expr, but not POSIX compliant.
+*and
   expr1 expr2
-Two expressions in a row are taken to be joined with an implied "and"; expr2 is not evaluated if expr1 is false.
   expr1 -a expr2
-Same as expr1 expr2.
+  expr1 -and expr2 (not POSIX compliant.)
-  expr1 -and expr2
-Same as expr1 expr2, but not POSIX compliant.
- expr1 -o expr2
+*or
-Or; expr2 is not evaluated if expr1 is true.
   expr1 -or expr2
-Same as expr1 -o expr2, but not POSIX compliant.
+ expr1 -o expr2 (not POSIX compliant.)
+*liste
   expr1 , expr2
-List;  both expr1 and expr2 are always evaluated.  The value of expr1 is discarded; the value of the list is the value of expr2. The comma operator can be useful for searching for several different types of thing, but traversing the filesystem hierarchy only once.  The -fprintf action can be used to list the various matched items into several different output files.
