Linux Shell Scripting Cookbook - Third Edition

How it works...

First of all, we use the source command to include the TwitterOAuth.sh library, so we can use its functions to access Twitter. The TO_init function initializes the library.

Every app needs to get an OAuth token and token secret the first time it is used. If these are not present, we use the TO_access_token_helper library function to acquire them. Once we have the tokens, we save them to a config file so we can simply source it the next time the script is run.

The TO_statuses_home_timeline library function fetches the tweets from Twitter. This data is retuned as a single long string in JSON format, which starts like this:

[{"created_at":"Thu Nov 10 14:45:20 +0000    
"016","id":7...9,"id_str":"7...9","text":"Dining...
