lower case to upper case string conversion in shell script

How can convert a Lower case variable value to an upper case in the kron shell script.

Check the man page for the tr command - you can use it to change a variable also.

The next example translates all lower-case characters in
file1 to upper-case and writes the results to standard
output.

tr "[:lower:]" "[:upper:]" <file1

With the korn shell, you can use typeset to make the shell do this without a separate process:

typeset -u two
one="something"
two=$one
echo $one $two

Anything stored in the variable "two" will be changed to upper case.

You can use the "dd" command too :

dd if=original_file of=new_file conv=ucase

I hope help you
