Why so much ....
calIs 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.
