Sydney Cityrail (131500) Timetable on Command-line (ver: 0.2)

Sydney CiryRail (www.131500.info) changed how parameters are fed in the URL from user's browser which broke my previous command line attempt.

Changes in this version:

• Time format to use with '-t' is: "16:00" or "04:08:pm"
• Date format to use with '-d' is: "2010:08:24"

Here is a fixed version (0.2) of the script:

    1 #!/bin/bash -e
    2 
    3 print_url=0
    4 timeout=10
    5 
    6 from_sta='Central'
    7 dest_sta='Town+Hall'
