I want to focus the first apart of this series on having bash display useful information in an easily accessible and concise way. For example, the first thing I do each morning is run my "update" script which displays the time, my schedule for the day and the weather, which looks something like this:
Hello jared, How are you today?
Current Date and Time:Fri Feb 26 09:00:40 MST 2010
Your Schedule:
Mon Feb 22 12:00am Zone 4
Fri Feb 26 12:00am Safety Kids Fair
6:30am Scriptures
11:00am Preschool time
Sat Feb 27 9:30am Food Co-op Pick up
Current Weather Conditons:Current conditions at UT (KSLC)
Last updated Feb 26, 2010 - 10:53 AM EST / 2010.02.26 1553 UTC
Wind: from the SSE (160 degrees) at 13 MPH (11 KT)
Sky conditions: mostly cloudy
Temperature: 35.1 F (1.7 C)
Relative Humidity: 69%
City Forecast for Salt Lake City, UT
Here is the script I use in my .bashrc file.
function update() # Current date, time, weather and calendar
(
echo -e "\nHello $USER, How are you today?"
echo -e "\nCurrent Date and Time: $NC " ; date
echo -e "\nYour Schedule: $NC " ; gcalcli agenda head
echo -e "\nCurrent Weather Conditons: $NC " ; weather head -n 7
echo ""
)
Let me run through this function. As you can see it's all just echo commands spewing out the information I desire. I begin by having bash say "Hello" to me. Just because it's a shell doesn't mean it can't be polite. Next it displays the current date and time which is followed by my schedule for the day. My schedule is produced by a cool little app called gcalcli which was a Google summer of code project that displays your google calendar on the command line. I blogged about this app previously here. I then finish things up with the weather using the weather-utils application. I have the weather command set up as an alias (which I'll cover in another segment) to display my local weather.
As mentioned previously, this is the first command I type into the terminal when I first wake up, which gives me a quick and concise outlook for the day.
Well, I hope this was interesting to some of you. My next installment will cover displaying useful system information. So until then... enjoy!
