Lamento decirte que no me funciona:
- ----------------------------------------------------
#!/bin/bash
horac=echo "date" | cut -f4 -d" " | cut -f1 -d":"
minutosc=echo "date" | cut -f4 -d" " | cut -f2 -d":"
segundosc=echo "date" | cut -f4 -d" " | cut -f3 -d":"
hc=$(( $horac * 60 + $minutosc + $segundosc / 60 ))
echo $hc
- -----------------------------------------------------
