data array needs to change upper case to lower case

Hi all,

i have a data array as followes.
Code:
ARRAY[0]=DFSG345GGG
ARRAY[1]=234FDFG090
ARRAY[2]=VDFVGBGHH
so on..........

i need all english letters to be change to lower case. So i am expecting to see
Code:
ARRAY[0]=dfsg345ggg
ARRAY[1]=234fdfg090
ARRAY[2]=vdfvgbghh
so on........

If i have to copy this data in to a 2nd array to do this, i am ok. But it would be nice if i only need one array. Can someone please help me here?
Smilie


by the way, i set the array as follows.
Code:
set -A array `grep -v "#" ${file}`

This is in Kshell

This is a bash example
Code:
#!/bin/bash
ARRAY[0]=DFSG345GGG
ARRAY[1]=234FDFG090
ARRAY[2]=VDFVGBGHH

x=0;while [ ${x} -lt ${#ARRAY[*]} ] ; do ARRAY[$x]=$(tr [A-Z] [a-z] <<< ${ARRAY[$x]}); let x++; done
x=0;while [ ${x} -lt ${#ARRAY[*]} ] ; do echo ${ARRAY[$x]}; let x++; done

and this is a bash 4.x only , shell only solution
Code:
#!/bin/bash

ARRAY[0]=DFSG345GGG
ARRAY[1]=234FDFG090
ARRAY[2]=VDFVGBGHH

x=0;while [ ${x} -lt ${#ARRAY[*]} ] ; do ARRAY[$x]=${ARRAY[$x],,}; let x++; done
x=0;while [ ${x} -lt ${#ARRAY[*]} ] ; do echo ${ARRAY[$x]}; let x++; done

This should do it - currently typing on a pc so can't test it...

Code:
for array in ${array[@]}
do
   echo $array  | tr '[:upper:]' '[:lower:]'
done

i tried both, but i still get errors. Right now code is,

set -A array `grep -v "#" ${file}`
x=0;while [ ${x} -lt ${#ARRAY[*]} ] ; do ARRAY[$x]=$(tr [A-Z] [a-z] <<< ${ARRAY[$x]}); let x++; done
x=0;while [ ${x} -lt ${#ARRAY[*]} ] ; do echo ${ARRAY[$x]}; let x++; done

You can try any one of these:
Code:
set -A array `tr '[A-Z]' '[a-z]' < file`

Code:
set -A array `tr '[[:upper:]]' '[[:lower:]]' < file`
