Quick Calendars
Sometimes when you’re working away, you find yourself with a need for a calendar. While most Linux distros have pretty and useful GUI calendar programs, they take a bit to fire up and render. Wouldn’t it be nice to have just a plain text calendar at your disposal anytime?
There is such a tool in Linux. Launched with the cal command, you can view a single calendar of the current month, multiple calendars, or calendars for the current year. You can even choose a Julian or Gregorian calendar. Here are some command line tweaks to the calendar command:
| Option | Action |
| -1 | displays single month output (default) |
| -3 | displays previous/current/next month output |
| -m | displays Monday as first day of week |
| -j | displays Julian dates | -y | displays calendar for current year |
So, for example, if you need a quick look at a 3-month calendar using Monday as the first day of the week, your command would be:
cal -3m
The cal command is one of those hidden tweakable tools that makes Linux a truly different and useful OS.
