expr expression<br />
The expr utility will evaluate an expression and write the result to standard output.<br />
The formation of the expression to be evaluated is shown as follows. (expr, expr1,<br />
and expr2 can be decimal integer valued arguments or strings.)<br />
Note: The first six expressions return the result of a decimal integer comparison if<br />
both arguments are integers. Otherwise, they return the result of a string<br />
comparison. The result of each comparison will be 1 if the specified relationship is<br />
true, or 0 if the relationship is false.<br />
Expression Description<br />
expr1 = expr2 Equal.<br />
expr1 > expr2 Greater than.<br />
expr1 >= expr2 Greater than or equal.<br />
expr1 < expr2 Less than.<br />
