A simple bash utility to finding the free space. (idk tbh)

space

#!/bin/bash

# Finding the base drive
drive_name=`df -h | rev | grep -E '^/\s' | rev | cut -d ' ' -f 1 | rev | cut -d '/' -f 1 | rev`

if [[ $# == 1 ]]; then
	drive_name=$1
fi

res=`df -h | grep $drive_name`

if [[ $? != 0 ]]; then
	echo "[!] $drive_name is an invalid drive!"
	exit 1
fi

total=`echo $res | cut -d ' ' -f 2`
used=`echo $res | cut -d ' ' -f 3`
free=`echo $res | cut -d ' ' -f 4`
percent=`echo $res | cut -d ' ' -f 5`
mount=`echo $res | cut -d ' ' -f 6`

echo "Drive : $drive_name"
echo "Total : $total"
echo "Used  : $used ($percent)"
echo "Free  : $free"
echo "Mount : $mount"
