The ical command is a simple utility for displaying a calendar on the terminal. It provides a text-based calendar output, typically for the current month. It supports displaying calendars for specific months and years, allowing you to view past or future dates. The output is generally basic, focusing on presenting the dates in a readable format. ical is often used for quick reference within a terminal session.
While functionally similar to the standard cal command, ical may offer slight variations in output formatting or options depending on the specific implementation and system. It's a convenient tool for users who prefer to work within the command line environment and need a readily accessible calendar. You can customize the output using parameters such as the year or month.

ical without arguments shows current month's calendar. ical 10 2024 shows the calendar for October 2024.
