Linux Command Line
The ‘calendar’ command on Linux is a simple yet powerful tool for managing and displaying calendars. It is commonly used to view upcoming events and schedule appointments, but it can also be used for other purposes such as creating reminders or tracking deadlines.
To use the ‘calendar’ command, simply open a terminal window and type ‘calendar’ followed by any options or arguments. For example, to view the current month’s calendar, you would type ‘calendar’ and press enter. To view a specific month or year, you can use the -m or -y option, respectively. For example, ‘calendar -m 5’ would display the calendar for May, while ‘calendar -y 2022’ would display the calendar for the year 2022.
One of the most useful features of the ‘calendar’ command is its ability to display upcoming events. You can add events to your calendar by using the -A option, followed by the number of days in advance that you want to view. For example, ‘calendar -A 7’ would display all events in the next 7 days.
Another useful feature of the ‘calendar’ command is its ability to display holidays. To display holidays for a specific country, use the -H option followed by the country code. For example, ‘calendar -H us’ would display all US holidays.
You can also use the ‘calendar’ command to create reminders by using the -e option followed by the event and the time. For example, ‘calendar -e “Meeting with John at 2pm” 14:00’ would create a reminder for a meeting with John at 2pm on the current day.
In addition to these basic features, the ‘calendar’ command also supports a number of other options and arguments that can be used for more advanced tasks. For example, the -l option can be used to display the calendar in landscape mode, and the -C option can be used to display the calendar in color.
The ‘calendar’ command is a versatile and easy-to-use tool that can help you stay organized and on top of your schedule. Whether you’re a student, a professional, or just someone who wants to stay on top of their appointments and events, this command is a must-have for anyone who wants to take control of their calendar.
Examples:
- To view calendar for May 2022:
calendar -m 5 -y 2022 - To view all events in next 7 days:
calendar -A 7 - To view all holidays for US:
calendar -H us - To create reminder for meeting at 2pm today:
calendar -e "Meeting with John at 2pm" 14:00 - To view the calendar in landscape mode:
calendar -l - To view the calendar in color :
calendar -C
Of course this is a command that is generally not used much any more. It is much simpler to use Outlook, or the calendar option on your Mac etc. Of course it can be fun to explore the history and more quirky side of Linux and Unix systems. Some of us are old enough to remember “pine” the text mail client.
