Campimeter.sh for macOS

Hi Neo...

Quote:

I tend to have a low attention span, so when I get a proof-of-concept like this up and running (and prove it works), even if the final results are not "polished", I then want to "call it good enough" and quickly move on to the next project.

This is me too except for the attention span. As soon as I find a solution to something I let others better it.
And as for doing something different I have done some bizarre stuff on here... <wink> /Me awaits the mickey take... ;oD
OT: Here is a small snippet for a terminal window you might like under OSX 10.14.6 on this MBP, solved and going into the Campimeter code.

Code:

#!/bin/bash
# Campimeter.sh

clear

# Set terminal to full screen and default sizes.
set_size()
{
    osascript << "FULL_SCREEN"
        tell application "Terminal" to activate
        tell application "System Events" to keystroke "f" using { command down, control down }
        delay 3
FULL_SCREEN
}

initialise()
{
    clear
    printf "%b" "\033[0;30;47m"
    clear
    SIZE=( $( stty size ) )
    VERT_CENTRE=$(( ${SIZE[0]} / 2 ))
    HORIZ_CENTRE=$(( ${SIZE[1]} / 2 ))
    printf "%b" "\033[${VERT_CENTRE};${HORIZ_CENTRE}f\033[0;30;42m  \033[0;30;47m\033[1;1f"
}

set_size

initialise

printf "\033[33;33f\033[1;31;47m*\033[0;30;47m\033[1;1f"

sleep 3

set_size

Enjoy...

tput

tput(1) 						      General Commands Manual							   tput(1)

NAME

       tput - query terminfo database

SYNOPSIS

       type] capname...

       type] capname [parms...]

DESCRIPTION

       The  command  uses the database to make terminal-dependent capabilities and information available to the shell (see terminfo(4)).  The com-
       mand outputs a string if the attribute (capname) is of type string, or an integer if the attribute is of type integer.  If the attribute is
       of type boolean, simply sets the exit code for TRUE, for FALSE), and produces no output.

   Command-line Arguments
       The command recognizes the following command-line arguments:

	      Indicates the type of terminal.
			     Normally this flag is unnecessary because the default is taken from the environment variable

	      capname	     Indicates the attribute from the database.  See terminfo(4).  In addition, the following capnames are supported:

				  Echo the clear-screen sequence for the current terminal.

				  Echo the initialize sequence for the current terminal.

				  Echo the sequence that will reset the current terminal.

	      parms	     If the capname takes optional numeric parameters, the parms will be placed in the string output by

	      The	     capnames  are  read  from stdin and multiple capnames are allowed.  Only one capname is allowed per line when reading
			     from stdin.

EXTERNAL INFLUENCES

   Environment Variables
       determines the locale to use.  This overrides settings of other environment variables.

       determines the language to use for messages.

       determines the terminal type if the option is not specified.

EXAMPLES

       Echo clear-screen sequence for the current terminal.

       Print the number of columns for the current terminal.

       Print the number of columns for the 70092 terminal.

       Set shell variable to stand-out-mode sequence for current terminal.

       This might be followed by a prompt:

       Set exit code to indicate if current terminal is a hard copy terminal.

       Clear the screen, move the cursor to line 10, column 20 and turn on bold.

RETURN VALUE

       If capname is of type boolean, then the exit code is set to for true and for false.

       If capname is not of type boolean and fails, an error message is printed, and exit code is set to one of the  following	depending  on  the
       failure:

	      The capability name is of type integer and does not exist.
	      Usage error.
	      Unknown terminal type.
	      Unknown capability name.
	      An error occurred.

       If  the	exit  code  is a is printed if a capability name of type integer is requested for a terminal that has no entry for that capability
       name in the database (such as
