The command "jcal -3" is used to display the calendar for the previous three months (including the current month) in the Julian calendar format.
The "jcal" command is specific to UNIX-based systems and is used to display the calendar in different formats. In this case, the option "-3" indicates that we want to display the calendar for the previous three months. The current month will also be included in the output.
For example, if today is September, running the command "jcal -3" will display the calendar for September, August, and July in the Julian calendar format. This can be helpful for quickly checking previous months' dates and planning purposes.
