Pequeno experimento para mostrar a hora atual no prompt usando emoji:
function prompt_char {
if [ $UID -eq 0 ]; then echo "#"; else echo λ; fi
}
clock_array=( )
function check_hour {
hour_24=`date "+%H"`
hour=`echo "$hour_24 % 12" | bc`
if [ "$hour" -eq 0 ]; then
hour=12
fi
minute=`date "+%M"`
if [ "$minute" -ge 45 -o "$minute" -le 15 ]; then
clock_array_shift=-1
if [ "$minute" -le 59 -a "$minute" -ge 45 ]; then
hour=`echo "$hour + 1" | bc`
fi
else
clock_array_shift=0
fi
clock_index=`echo "(($hour * 2) + $clock_array_shift) % 24" | bc`
clock=${clock_array[$clock_index]}
echo " $clock "
}
