Lower case to upper case letter
Is there any shell command is ther to convert the lower case letters into upper case letters in a file content ( not a C or C++ coding )? Actualy my think is, i have the numbers in hexa decimal format i want convert it into decimal format. The "bc" calculater is there for converting the hexa decimal format to decimal format. But it will accept the hexa values in FF not in ff. I have the value of ff format. so i need to convert it into uppercase format.
Thanks in advance....
