Create List of Distracting Websites

Bear in mind that this step is optional, if you skip this step shFokus will create it automatically. By default it will block Facebook, Youtube, Instagram, Twitter, Twitch and Netflix.

Let's start by creating list of websites that should be blocked. By default shFokus will search for ~/.shfokus file to determine list of websites. In this example we are going to block Facebook and Twitter.

$ vi ~/.shfokus

facebook.com
www.facebook.coom
twitter.com
www.twitter.com

As you can see above you need to specify one domain per line.

Block Distracting Websites

Because modifying HOSTS file /etc/hosts require root privilege then you need to run the command as root or with sudo. To start blocking use option -a block.

$ sudo bash ./shfokus.sh -a block

Stay focus and productive -- Have a great day :)

If you're concern about what shFokus about to write to your HOSTS file then you can run in dry-run mode first. By running in dry-run mode it will not touch your HOSTS file instead it will print to STDOUT.

$ bash ./shfokus.sh -a block -r

...
# Added by Docker Desktop
# To allow the same kube context to work on the host and the container:
127.0.0.1 kubernetes.docker.internal
# End of section
# shfokus_begin - DO NOT TOUCH
0.0.0.0 facebook.com www.facebook.coom twitter.com www.twitter.com
# shfokus_end
Stay focus and productive -- Have a great day :)

Notice that shFokus add new entry between # shfokus_begin and # shfokus_end at the end of HOSTS file.

Block for Specific Duration

If you want block distracting websites for specific duration then use -t option. It accept value in minutes.

$ sudo bash ./shfokus.sh -a block -t 60

Stay focus and productive -- Have a great day :)
Block will be released in 3587 sec... CTRL+C to unblock

Block will automatically released in 60 minutes. If you want to release earlier use CTRL+C.

----- Interrupted by CTRL+C -----

Unblock Distracting Websites

To release block of distracting websites use option -a unblock. It will remove values from your HOSTS file.

$ sudo bash ./shfokus.sh -a unblock

Distracting websites has been unblocked -- Enjoy your day :)

Unblock Distracting Websites for Specific Duration

If you want unblock websites for specific duration then use -t option. Same as block it accept value in minutes.

$ sudo bash ./shfokus.sh -a unblock -t 10

Websites will be blocked in ${SECONDS_LEFT} sec... CTRL+C to block

Websites will be unblocked temporarily for 10 minutes. If you want to block earlier use CTRL+C.
