Converting the case of the string?

Hi

i have a string value in a variable STR
eg. STR="ABSDSCSFS"

How can be convert it to LOWERCASE in the script?

Thanks

One way using tr is

echo "$STR" | tr '[:upper:]' '[:lower:]'

Hi

What to do if we want permanent change in STR not just echoing like below??????

STR=$(echo "$STR" | tr '[:upper:]' '[:lower:]')

Please refer to the link,

You can use typeset.
