Linux Alarm Clock

I have an alarm clock in Mac that wakes up my computer from sleep at predestined time and plays my selected music. I was wondering if there was a linux equivalent that could wake up the computer, so I wouldn't have to return to Mac every night.

The gist of it is:

# date -d TIME +%s > /sys/class/rtc/rtc0/wakealarm

Re: Linux Alarm Clock

Wintervenom, just a friendly suggestion.

Can you not use the various colors in your posts? I use a dark theme and man it makes it difficult to read the blue and green in your post.
