The ncal command itself does not have built-in options to highlight specific dates directly in its output. However, you can achieve this by using additional tools or scripting.
One common approach is to use awk or sed to process the output of ncal and highlight specific dates. Here's an example using awk to highlight a specific date in the output:
ncal | awk '{for(i=1;i<=NF;i++) if($i=="15") $i="\033[1;31m"$i"\033[0m"; print}'In this example, the date "15" is highlighted in red. You can change "15" to any date you want to highlight.
If you need more advanced formatting, consider using a programming language like Python with libraries such as matplotlib to create a custom calendar visualization.
