+	\-s file	true if the file exists and has a size > 0
+	\-t fd	true if file descriptor fd (default 1) is a terminal
+	\-z s	true if the string s has zero length
+	\-n s	true if the string s has nonzero length
+	s1 = s2	true if the strings s1 and s2 are identical
+	s1 != s2	true if the strings s1 and s2 are different

+The operators \fB\-gt\fR, \fB\-ge\fR, \fB\-ne\fR, \fB\-le\fR, and
+\fB\-lt\fR may be used as well.
+These operands may be combined with \fB\-a\fR (Boolean and), 
+\fB\-o\fR (Boolean or), !
+(negation).  
+The priority of \fB\-a\fR is higher than that of \fB\-o\fR.  
+Parentheses are permitted, but must be escaped to keep the shell from trying 
+to interpret them.
