  17 # Description:
  18 #
  19 # telenorsms is a script that connects to the Norwegian cell operator Telenor and sends SMS messages
  20 #
  21 # It requires curl or wget, xxd, tr, cat and sed. "tempfile" is also recommended, though the script should manage
  22 # to generate tempfiles itself.
  23 #
  24 # Your username (email) and password for your Telenor account need to be stored in ~/.telenorsms on two
  25 # separate lines:
  26 # ------------------------------------------
  27 # username=me@provider.com
  28 # password=awesome1
  29 # grabber=/home/me/bin/grabber
  30 # ------------------------------------------
  31 # As shown above, it is also strongly recommended to indicate the path to the "grabber" library,
  32 # which should be available where this script was downloaded from. Grabber does not need to be executable.
  33 #
  34 # You must have sent at least one message through the online interface, as it will ask you to verify your
  35 # cell phone number by entering a code received by SMS, the first time you use it.
  36 #
  37 # telenorsms supports using numbers and names stored in your online address book in the SMS section of
  38 # Telenor's pages. Messages can be sent to stored numbers using complete names or partial numbers.
  39 #
  40 # Examples:
  41 #   ./telenorsms Joe Hey man, how's it going?
  42 #   ./telenorsms +4711223344 This is a message.
  43 #   ./telenorsms 1122 This is a message.
  44 #
  45 # Comments welcome, improvements/patches twice as welcome.

  48 # Version history:
  49 #
  50 # 2009-02-03: Initial version - ivc
  51 # 2009-08-19: Support for local phonebook and various bug fixes - Håvard Gulldahl
  52 # 2012-07-29: Rewrite for Bash 4 with support for new "MineSider" setup and online phonebook - Øyvind 'bolt' Hvidsten
  53 # 2013-04-07: Minor style changes and comment cleanup - Øyvind 'bolt' Hvidsten
  54 # 2013-04-20: Updated to comply with changes on Telenor's website
  55 # 2013-06-15: Retry 3 times because of random cases of Ubuntu bug #965371 occuring on Telenor's server:
  56 #             GnuTLS: A TLS packet with unexpected length was received.
  57 #             Unable to establish SSL connection.
  58 # 2014-04-04: Updated to comply with changes on Telenor's website
  59 # 2014-08-26: Support for complaining about "technical error" on Telenor's website
  60 # 2014-08-27: Support for the -d (dry run) option, testing most of the script without sending a message
  61 # 2014-08-28: Support for the -a (force address book) option, used during debugging
  62 # 2014-10-01: Spelling error fix
  63 # 2014-10-18: Rewrote URL grabbing to use curl, as Telenor screwed up their TLS negotiation
  64 #             Use of wget can still be forced by adding [-w]
  65 #             Added several debugging features
  66 #             Note from debugging: URL encoding the "+" sign in "Logg+inn" breaks Telenor's form
  67 # 2014-10-19: Pushed the HTTP grabbing functionality to a separate file in order to unify the methods used
  68 #             across several scripts I'm maintaining that all have similar functionality.
  69 #             Deeply sorry for any inconvenience caused.
  70 # 2014-10-24: They changed the text "gjenstående SMS" to "gjenstående gratis SMS" for no reason. OK.
  71 # 2015-01-04: Added detection of the SMS counter breaking - no longer exiting with non-zero unless debugging
  72 # 2015-05-01: Minimal fix to support new link format for the login page
  73 # 2015-05-16: Updated to comply with changes to grabber
  74 # 2016-01-16: Updated to comply with changes to grabber (again)
