Working with calendars in the shell

Remind

Due to space limitations, I did not cover the Remind [7] console program in this issue: Its possibilities easily fill a separate article.

Conclusions

Creating calendars in the shell is a painless process, with numerous settings available for designing your final product. Simple date entries in the shell can be easily handled using your own scripts given the right choice of tools. You can also create selection calendars as an alternative for entering dates using dialog, YAD, or Zenity [8].
