SYNOPSIS
rain |
[-d delay] |
DESCRIPTION
rain is modeled after the VAX/VMS program
of the same name.
To obtain the proper effect, the -d option
may be used to specify a delay in milliseconds between each update.
Reasonable values are around 20–200. The default is based on the
terminal speed, computed via the following formula:
delay = speed / 9600 - 1As with any curses(3) program, the TERM
environment variable must be set (and exported) to the type of the terminal
being used.
