My third semester final exams are starting from next week. It is really high time now to start collecting notes from your dear friends. So i have decided to go eco-friendly this year.
Instead of taking xerox of the notes, you can take the images of the notes and then compile them into a single pdf file which is very handy and easy to read.

Go paperless!

If you are using Linux OS, it is pretty easy to accomplish this. Type the following commands in the terminal:

1. Install ImageMagick.
If you are on Ubuntu/debian system:

sudo apt-get install imagemagick

2. Copy all your images which you want to convert into pdf file in a single directory and then move to that <directory-location>

cd <directory-location-where-your-images-are-located>

3. Enter the following command to convert your images to pdf:

convert * notes.pdf

where notes.pdf is the desired single pdf output file.
If you want to compress,

convert -compress jpeg *.jpg notes.pdf

You can also use convert’s option -quality 100 to improve the resulting PDF.
