Any of the comparisons -ne, -gt, -ge, -lt,<br /> or -le may be used in place of -eq.<br /> <br /> These primaries may be combined with the following opera-<br /> tors:<br /> <br /> ! unary negation operator<br /> <br /> -a binary _a_n_d operator<br /> <br /> -o binary _o_r operator<br /> <br /> ( expr )<br /> parentheses for grouping.<br /> <br /> -a has higher precedence than -o. Notice that all the opera-<br /> tors and flags are separate arguments to _t_e_s_t. Notice also<br /> that parentheses are meaningful to the Shell and must be<br /> escaped.<br /> <br /> == SEE ALSO ==<br /> [[32v 1m sh|sh(1)]], [[32v 1m find|find(1)]]<br /> <br /> [[Category:32v man section 1]]</div>
