#!/bin/bash # File : ran-d0m.sh # By : MaartenDeBoer.nl, 181127 # Subject : Script to create randomized a (web)page (ran-d0m.com) # # RANDOM Each time this parameter is referenced, a random integer between # 0 and 32767 is generated. The sequence of random numbers may be # initialized by assigning a value to RANDOM. If RANDOM is unset, # it loses its special properties, even if it is subsequently # reset. #(0.2) : Added title #(0.3) : Added .rc #(0.4) : Added, # rows(TRLINES) & col''s (TDLINES) > 5. #(0.5) : Added Better HEX random, R_SIZE #(1.0) : Added T[DR]MIN, T[DR]MAX -> R[DR]LINES, DEVIDER -> T[DR]MAX (So can be set in RC-file) #(1.1) : Changed Rand TD's #(2.0) : Added TR height #(3.0),181210 : Added 1 single TABLE in single cell, added RAND_HEX_COLOR #(3.1),181210 : Added more TABLE #(3.2).181210 : Changed TRMIN #(3.3),181212 : Fixed TR-size (TRSIZE) #(3.5),181212 : Added LOCK-file #(4.0),181212 : Added random TD #(4.1),181213 : Mod.
