Show this month's calendar, with today's date highlighted

cal | grep --before-context 6 --after-context 6 --color -e " $(date +%e)" -e "^$(date +%e)"
Explanation: * The date command evaluated to today's date with blank padded on the left if single digit * The grep command search and highlight today's date * The --before-context and --after-context flags displays up to 6 lines before and after the line containing today's date; thus completes the calendar. I have tested this command on Mac OS X Leopard and Xubuntu 8.10

What Others Think

Why so much .... cal Is sufficient. Current date is highlighted already.

CodSpirit: Which system are you talking about? I tried cal alone on Mac OSX Leopard and on Xubuntu 8.10 and the current date is not highlighted.

cal | grep -C6 --color -e " $(date +%e)" -e "^(date +%e)"

The cal in OSX doesn't highlight. The one in RHEL (actually "ncal") does. This hack is handy for those cal's that don't highlight.
