Get your Google Calendar into TMUX

EDIT: If you need to have your caldav/owncloud calendar, have a look HERE.

The most time I work in the terminal in fullscreen mode for not getting disturbed. Therefore I like it to have my calendar(at least the next appointment) visible in my command line environment. I discovered a great tool for the command line called ‘gcalcli’. You can find it on github:

Install it via pip:

pip install gcalcli

After the installation you need to setup your account on the first connection. You can do this for example by requesting your agenda:

gcalcli agenda

A browser window will popup which is requesting your confirmation to manage your calendar:

After confirming you are able to query your calendar with the command line – GREAT! 😉

As wouldn’t that be cool enough, let’s put the calendar into tmux.

First we need to build the build the output we a few pipes and stuff:

gcalcli --nostarted --calendar "" agenda --nocolor | cut -d " " -f 4- | head -2 | tail -1 | sed "s/^ *//g" | sed "s/    / /g" | cut -c1-19

Let’s cut off the date, redundant spaces, empty lines and all the useless stuff and finally get only the next event in the calendar.
Also I only want the first 20 chars of the name, so let’s cut this ;).

Be sure to replace GOOGLE_USERNAME with your accountname(everything in front of

Now you have only the last element, so let’s get a nice calendar symbol and put it in our .tmux.conf.
Therefore your need to open your .tmux.conf modify the option ‘status-right’:
set -g status-right '📅 #(gcalcli --nostarted --calendar "" agenda --nocolor | cut -d " " -f 4- | head -2 | tail -1 | sed "s/^ *//g" | sed "s/    / /g" | cut -c1-19)'

So you are almost there, just save your file and reload your tmux config. So type your prefix(standard CTRL+B) and
:source-file ~/.tmux.conf

After a few seconds in the right bottom you should see your next event from the google calendar:

Nice! 🙂

In the next days I will write how to achieve this with your owncloud account.

Have fun and thanks for reading! 🙂


P.S.: Currently I am writing a bout about an effective workflow using tmux so don’t forget to opt in to the newsletter to get the latest updates on the work in progress.
