Block websites within a daily time range.
By simply making use of host entries in /etc/hosts, nodis blocks access to websites that distract you.
Recently, I've found myself more and more distracted, again, by the web. Having
some important stuff to finish for the end of the month, I'm sick of not
progressing on what really matters right now.
I've written this script as a crutch to recover from this kind of addiction to
direct futile satisfaction. As any crutch, I think it should be temporary.
Dependencies:
- awk (posix should work)
- grep
- cron
clone the repository and cd into it
git clone https://github.com/pldiiw/nodis --depth 1 && cd nodis
Move the scripts somewhere in your path and set proper permissions to them if necessary:
install -o root -g root -t /usr/local/bin nodis nodis_update_hosts.awk
Finally, add an entry to cron to update /etc/hosts every 10 minutes (or less if you wish to):
{ crontab -l; echo '*/10 * * * * nodis update' } | crontab -
Note: Make sure that $PATH is defined inside crontab
Here's the detailed help for nodis:

ENVIRONMENT VARIABLES:
HOSTS_FILE - The path to the hosts file, defaults to /etc/hosts
TIME FORMAT:
When specifying a time, the expected format should be parseable by
the date(1) command
NODIS ENTRY FORMAT:
The format used by nodis inside the hosts file is the following:
127.0.0.1 <domain> ## <start_time> <end_time>
You can manually edit the entries if you would like to, just be
aware that you can write the times like this (regexp): HH.?MM
Examples: 1430, 03:55, 22-01, 17h23
MULTIPLE TIME RANGES:
If you would like to block a domain for multiples time ranges, simply use the
block subcommand for each time range!
I'm open to any contribution, just post an issue and we will see together what we can do about it.
