How to use curl in a shell script?

I'm trying to run this shell script in order to install RVM in an Ubuntu box

#!/bin/bash
RVMHTTP="https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer"
CURLARGS="-f -s -S -k"

bash < <(curl $CURLARGS $RVMHTTP)

but I get the following error

Syntax error: Redirection unexpected

Also tested not using the variables, but same result, could you tell what I'm missing?

Firstly, your example is looking quite correct and works well on my machine. You may go another way.

curl $CURLARGS $RVMHTTP > ./install.sh

All output now storing in ./install.sh file, which you can edit and execute.


#!/bin/bash                                                                                                                                                                                     
CURL='/usr/bin/curl'
RVMHTTP="https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer"
CURLARGS="-f -s -S -k"

# you can store the result in a variable
raw="$($CURL $CURLARGS $RVMHTTP)"

# or you can redirect it into a file:
$CURL $CURLARGS $RVMHTTP > /tmp/rvm-installer

or:

Execute bash script from URL
