Automated scripts

This is a simple and very simple script! Not even worth mentioning as it does nothing but utilizes another command.Still let it be here.

#/bin/bash
df -H|awk 'BEGIN{i=0;j=0} $1~/\/dev/ \
{if($4~/M$/){i=i+($4/1000)}else{i=i+$4};j=j+$2} \
END{print"Free space:"i" GB";print"Total Space:"j" GB";print"Percentage Free:"i/j*100"%"}'

Its self explaining enough.
Sample output is:

vivek@vivek-desktop:~$ space
Free space:31.6 GB
Total Space:252 GB
Percentage Free:12.5397%
vivek@vivek-desktop:~$


Here is the content of my /etc/init.d/bootmisc.sh
I guess here I can add some scripts I need to run.
