#!/bin/bash cd /home/pi/space df -h > freespace.txt find /home/pi/space/freespace.txt -type f -exec egrep -w "/dev/root" {} \;  | cut -d\m -f3 > freespace2.txt find /home/pi/space/freespace2.txt -type f -exec egrep -w "" {} \;  | cut -d\m -f1 > freespace3.txt  space=$(cat /home/pi/space/freespace3.txt)      if [ "$space" -lt "100" ];        echo "you running out of disk space!"     fi 

you better use "du" "df".

code: select all

hp ~ # du . -s 64826032	. hp ~ #  

"man du" explain "." , "-s" you.
