Script to Calculate Number of Hours from Minutes

The following is a quick script that will convert minutes to hours and minutes as well as total hours in decimal form (1 hour, 30 minutes is 1.5 hours). Simply save the contents of the script below to a file, execute chmod +x filename on that file, and then run it with ./filename. Feel free to modify it to fit your needs.

#!/bin/sh

minutes=432

hrs=`echo "$minutes / 60" | bc`
min=`echo "$minutes % 60" | bc`
if [ $min -gt 0 ]; then
   if [ $min -le 2 ]; then hours=`echo "$hrs + .0" | bc`; fi
   if [ 3 -le $min -a $min -le 8 ]; then hours=`echo "$hrs + .1" | bc`; fi
   if [ 9 -le $min -a $min -le 14 ]; then hours=`echo "$hrs + .2" | bc`; fi
   if [ 15 -le $min -a $min -le 20 ]; then hours=`echo "$hrs + .3" | bc`; fi
   if [ 21 -le $min -a $min -le 26 ]; then hours=`echo "$hrs + .4" | bc`; fi
   if [ 27 -le $min -a $min -le 32 ]; then hours=`echo "$hrs + .5" | bc`; fi
   if [ 33 -le $min -a $min -le 38 ]; then hours=`echo "$hrs + .6" | bc`; fi
   if [ 39 -le $min -a $min -le 44 ]; then hours=`echo "$hrs + .7" | bc`; fi
   if [ 45 -le $min -a $min -le 50 ]; then hours=`echo "$hrs + .8" | bc`; fi
   if [ 51 -le $min -a $min -le 56 ]; then hours=`echo "$hrs + .9" | bc`; fi
   if [ 57 -le $min -a $min -le 60 ]; then hours=`echo "$hrs + 1.0" | bc`; fi
fi

echo "Minutes Entered: $minutes"
echo "$hrs Hours, $min Minutes ($hours Hours)"
