How to make the `cal` tool in OSX highlight the current day

calosx

In Ubuntu and Fedora, when I type cal on the command line I get an ASCII calendar with the current day highlighted.

In OSX, when I type cal, I get an ASCII calendar but no day is highlighted.

How can I get the highlighting of the current date in OSX?

The following prints the current date with a reversed field which is replaced in cal by sed.

ptd=$(date -j +%d)
ctd=$(printf "\033[0;7m"$ptd"\033[0m")
cal | sed 's/'"$ptd"'/'"$ctd"'/'

Highlight the current date in cal

I don't know how to highlight the day in the year calendar cal -y with just regular expressions, but the reason your example was not working for single digit dates is because $(date +%e) prepends a space to the output when the date has a single digit.

This will work:

cal | grep --color -EC6 "\b$(date +%e | sed "s/ //g")"

Cal no space delimiter

You could use sed for that.

$ cal|sed -e '1n;s/\(..\)\(.\)/\1,\2/g'

1n prints the first line and moves to the next. The replacement then takes the chars three by three and prints the first two followed by , then the third.
