case conversion in bash script??

I am writing a bash script.

Lets say,

VAR="Rakesh"

Now I want to convert the content of VAR ($VAR) to lowercase. How can I do in bash.

i.e if I echo $VAR, I should get 'rakesh' not 'Rakesh'

new=`echo $old | tr '[A-Z' '[a-z]'`



In other words, it has nothing to do with Bash: you could do this in any shell that allows backtick or some other way to accept the output of external cammands.

new=$(echo $old | tr '[A-Z' '[a-z]')

is a "Bash" solution, but the work is still done by "tr".

One can also use awk for the same:-

new = echo $old | awk '{print tolower($0)}'

~rakesh
