UNIX for Dummies Questions & Answers

Hello,

I'm trying to take a 3 character date and change it to uppercase, does anyone know how to do that?

Currently, all commands that I know of for changing strings/variables to uppercase change the command itself to uppercase, not the output.

Here is what I've tried:

date="date +%b"
echo $date
Aug

echo $date | tr "a-z" "A-Z"
DATE +%B
echo "$date" | tr '[a-z]' '[A-Z]'
DATE +%B

OR:
DATE=`echo $date|awk '{print toupper($0)}'`
$DATE
ksh: DATE: not found

OR:
print $date|sed 'y/[a-z]/[A-Z]'
sed: Function y/[a-z]/[A-Z] cannot be parsed.

Does anyone know how to get that date to all CAPS? (as you see above, it currently reads "Aug"...)

Code:

date | tr -s '[:lower:]'  '[:upper:]'

Please consider using the forum search - this same question has been asked several times in the past two weeks.

Thank you Jim!

I adapted it to $date | tr -s '[:lower:]' '[:upper:]' and it worked - my apologies.

I did try to find the answers, but I see that the phrases I searched on were bad because I couldn't seem to find the threads you referred to. That seems to be a big challenge to finding answers anywhere - getting the lingo right.

I'm trying to figure out how people would search on something like that - "Changing shell variables to uppercase" or something?

The more useful question would probably be: Any advice on good searching methods?

Thanks again, Jim, in advance
