Question
I used advice from jim mcnamara, so :
Code:
echo "$var" | tr -s '[:lower:]'  '[:upper:]' | read tmp
var=$tmp

But when I call function which uses this mechanism I get such error :
./filterEngine.ksh[11]: February: not found

# cat filterEngine.ksh
Code:
#!/bin/ksh

Hello,

other solution that could be used for other languages is:

Create a file names (i.e) months with the content:
Code:
styczen:January
luty:February
marzec:March
...and so on...

then, if in the variable month you have the user entered, you can:

Code:
grep -i $month months | cut -d: -f 2

and the result will be the english name...

bash 4
Code:
# name=january
# echo ${name^}
January

or..
Code:
# name=jAnUaRy
# first=${name:0:1}
# rest=${name:1}
# name=${first^}${rest,,}
# echo $name
January
