About one month ago, it was April 1st, I attached two more lines to the
.bashrc of Rumpel (he is co-worker and has to operate that day).
These two lines you can see here:
# kleiner april-scherz von dein freund martin :P export PROMPT_COMMAND='if [ $RANDOM -le 32000 ]; then printf "\\0337\\033[%d;%dH\\033[4%dm \\033[m\\0338" $((RANDOM%LINES+1)) $((RANDOM%COLUMNS+1)) $((RANDOM%8)); fi'
With each appearance of the bash prompt this command paints one pixel in the console with a random color. No respect to important content beyond this painting. That can really be annoying and he was always wondering why this happens! For more than one month, until now!
Today I lift the secret, so Rumpel, I’m very sorry ;)
