# NAME

rpn - Reverse Polish Notation calculation

# SYNOPSIS

    optex -Mrpn command ...

# VERSION

Version 1.01

# DESCRIPTION

**rpn** is a filter module for **optex** command to detect arguments

which look like Reverse Polish Notation (RPN), and replace them by the

result of calculation.

See [Math::RPN](https://metacpan.org/pod/Math%3A%3ARPN) for Reverse Polish Notation detail.

Since RPN part requires two terms at least,

    optex -Mrpn echo RAND

print just "RAND".  Use something like `RAND,0+` to get random

number.

# EXAMPLE

Prevent macOS to suspend for 5 hours.

    $ optex -Mrpn caffeinate -d -t 3600,5*

# INSTALL

## CPANMINUS
