Focus

Focus adds domains of your choice to /etc/hosts. It then blocks and unblocks them by uncommenting and commenting those domains.

Install

How it works

focus adds domains to /etc/hosts in a block surrounded by "#focus#" and "#eofocus". If focus is deactivated, adding domains will add them commented to /etc/hosts.

#focus#
#127.0.0.2 facebook.com
#eofocus#

Activating focus will uncomment the domains.

#focus#
127.0.0.2 facebook.com
#eofocus#

Adding domains while focus is activated will add them to the block uncommented.

#focus#
127.0.0.2 facebook.com
127.0.0.2 twitter.com
#eofocus#
