in reply to Case conversion

I should probably phase this a bit better. I have a varible and this can be in either lower or upper case. For me to use this variable it needs to be in upper case. What I would like to achieve is to convert the variable to upper case if it is currently lower case otherwise just use it as it is. I hope that's better

    The simplest (and thus probably the desired) solution is to use uc anyway, it won't modify upper-case strings and will only turn lower-case to upper-case.

    Try: 
    perl -e 'print "hello " . uc "WOrld"'
