set variable to output and immediately lowercase it?

set variable to output and immediately lowercase it?

[TJ Luoma]

Is there a (reasonably sane) way to combine these into one line:

	FOO=$(echo HeLlo WoRlD)

	FOO="${FOO:l}"

I mean, I know I could do this:

	FOO=$(echo HeLlo WoRlD | tr '[:upper:]' '[:lower:]')

but I mean is it possible to do this all in zsh.


I tried

	FOO=$(echo HeLlo WoRlD):l

and

	FOO=($(echo HeLlo WoRlD):l)

but they don't work, it just adds ":l" to the end of the variable.

typeset -l FOO="$(echo HeLlo WoRlD)"

or more typically

typeset -l FOO
FOO=$(echo HeLlo WoRlD)

Try small `l' parameter modifier
	FOO=${$(echo HeLlo WoRlD):l}
or capital `L' parameter expansion flag
	FOO=${(L)$(echo HeLlo WoRlD)}

Many thanks!

I hope that someday I feel like more than a 'slightly advanced novice'
at zsh :-)
