Specifying a range within case/esac
Complete Unix beginner here. I basically have this script -
Quote:
time1=`date +%l:%M`

case `date +%H` in
"00") time2="in the early morning" ;;
"01") time2="in the early morning" ;;
"02") time2="in the early morning" ;;
"03") time2="in the early morning" ;;
"04") time2="in the early morning" ;;
"05") time2="in the morning" ;;
"06") time2="in the morning" ;;
"07") time2="in the morning" ;;
"08") time2="in the morning" ;;
"09") time2="in the morning" ;;
"10") time2="in the morning" ;;
"11") time2="in the morning" ;;
"12") time2="in the afternoon" ;;
"13") time2="in the afternoon" ;;
"14") time2="in the afternoon" ;;
"15") time2="in the afternoon" ;;
"16") time2="in the afternoon" ;;
"17") time2="in the evening" ;;
"18") time2="in the evening" ;;
"19") time2="in the evening" ;;
"20") time2="at night" ;;
"21") time2="at night" ;;
"22") time2="at night" ;;
"23") time2="at night" ;;
esac

echo "The time is$time1 $time2"
This seems to work fine. I want to try and shorten it by making it something like this -

Quote:
time1=`date +%l:%M`

case `date +%H` in
[00-04] ) time2="in the early morning" #and so on...
esac
This isn't working. I think it's probably to do with the zero padding that `date +%H` gives me, but if I use `date +%k`, I get a space at the start of single numbers, so that doesn't work either... Can anyone tell me where I'm going wrong?

Thanks in advance.

Hi.

You could shorten it as such:

Code:
time1=`date +%l:%M`

case `date +%H` in
0[0-4]) time2="in the early morning" ;;
0[5-9]|1[01]) time2="in the morning" ;;
1[2-6]) time2="in the afternoon" ;;
1[7-9]) time2="in the evening" ;;
2[0-3]) time2="at night" ;;
esac

echo "The time is$time1 $time2"

Thank you so much!

Just one more thing, could you explain what is going on in this line of your script? Specifically, the |1[01] part.

Quote:
0[5-9]|1[01]) time2="in the morning"
Edit: Actually, just worked it out. Thanks again!

By the way, is there an easy way to get the date command to show the st/nd/rd/th suffix for days?

Looking through man date, I don't see that it has that option.
