cal 20 July

C.
cal 7 2010

date

Explanation:

The cal 7 2010 command will display the calendar of July 2010.
What is the cal command?
The cal command prints an ASCII calendar of the current month.
Syntax: cal [month] [year]
Given a month and year as arguments, cal displays the calendar for that particular month of the
given year.
When a single numeric argument (such as 2005) is given, cal will display a calendar for the given
year. Always use a fourdigit year. For example, the command cal 05 will display the calendar for
the year 05, not the year
2005.
Answer option B is incorrect. The cal 20 July command will display only the month and year, and
not the date.

Answer option A is incorrect. The cal command will display the calendar of the current month.
Answer option D is incorrect. The date command will display the current date and time of the
system.
