Use gcalcli for google calendar
I use cli `pip install –user gcalcli parsedatetime` to install gcalcli into HOME folder.
Usage is simple. `gcalcli calw` is enough.
For multiple accounts, `mkdir -p ~/.config/gcacli-work; gcalcli –configFolder ~/.config/gcacli-work calw`.
Use paste (Unix) to join two calendars in bash,
paste <(gcalcli --configFolder ~/.config/gcacli-work calw) <(gcalcli calw)
Edit crontab to remind me about the calendar events,
*/10 * * * * $HOME/.local/bin/gcalcli remind
*/10 * * * * $HOME/.local/bin/gcalcli --configFolder $HOME/.config/gcacli-work remind
