The cal utility displays the calendar in the traditional horizontal format. It output show the current month and date.

The ncal(New Calendar) command displays the calendar in the vertical format.

-h = don't highlighting today's date

command = ncal -h and press enter



*This cal -h command does not work in cal utility. 

  • Display the Specified Month

The cal/ncal commands displays the current month by default, but we can use the -m[month [numeric value] ] command line option in order to have a specific month displayed. In this command we use the numeric value[1-12]  or month name example jan-dec that represent the specified month.

  • command 

 cal/ncal -m[1-12] or cal/ncal -m[jan-dec]

  • Command
