Change a parameter to be in capital letters

Shell Programming and Scripting
1

Hi,
I have a korn shell script with 1 parameter.
My script deletes certain files, for example....

sid=$1

rm $ORC/dbs/orapwd${sid} #orapwddb1

rm $ORC/dbs/lk${sid} #lkDB1

In the first file, the $sid must be in small letters and in the second file, the $sid must be in capital letters. Is there a way of doing this, so that the second $sid will be in capital letters?

this one,

sid=$1

rm $ORC/dbs/orapwd${sid} #orapwddb1

sid=`echo $sid | tr '[a-z]' '[A-Z]'`
rm $ORC/dbs/lk${sid} #lkDB1
3

Using awk

SID=`echo $sid|awk '{print toupper($0)}'`

Thanks a lot!

$mah="hello"
$ typeset -u mah
$ echo $mah

Just typeset -u the variable, it will get converted into uppercase
