def extract_pkg(package_file):
result = {}
package_file = package_file.replace('.deb', '')
(result['package'], tmp) = package_file.split('_')
(tmp, result['build']) = tmp.split('-')
tmp = tmp.split('.')

This script is designed to work with an HooToo IPCamera you can for example buy at http://goo.gl/V3H2W - It will take one picture every n seconds and store them named by current time in one folder so you later on can assemble them into a timelapse video.

Imports an image from a twain sane scanner, converts to jpg and saves it to the desktop of the current user, then opens it with Preview.app
#!/bin/bash
targetfile="scan_$( date +"%Y-%m-%d_%H-%M-%S" ).jpg"
# Get image from scanner
scanimage --format=tiff --resolution 300 > /tmp/scan.tiff

if [ $(grep -q 'cups' /tmp/scan.tiff ) ]; then
# Calculate size of file without error message
