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'
Got something to add? Send me email.

We are questioning more than the philosophy behind our dependence upon limited and limiting systems. We question the power structures that have grown up around such systems (Frank Herbert).

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)}'

little correction
new=$(echo $old | tr '[A-Z]' '[a-z]')
you missed the ']'
