RE: removing spaces in variables when using :t or :r or similar

["Alexandros Kozak" <agkozak@gmail.com>]

${${INSTALL_TO:t:r:l}// /}

seems to work.

Subject: removing spaces in variables when using :t or :r or similar

Let's use this variable as an example:

INSTALL_TO='/Applications/Keyboard Maestro.app'

Now, if I want to get just "keyboard maestro" I can use this:

$INSTALL_TO:t:r:l

But what if I want "keyboardmaestro" ?

I tried this:

echo "${INSTALL_TO:t:r:l// /}"

but that just produced this error:

zsh: unrecognized modifier

I realize I could do this:

FOO="${INSTALL_TO// /}"

echo "$FOO:t:r:l"

but I'd rather avoid using a second variable, if I can avoid it.

Is there a way to do that with zsh, or am I stuck just sending it to `tr -d ' '` ?

Thanks!
