![How to Use Curl in a Shell Script? [Duplicate]](https://docuprint.cloud68.co/uploads/how-to-use-curl-in-a-shell_1200.jpg)
I'm trying to run this shell script in order to install RVM in an Ubuntu box
#!/bin/bash
RVMHTTP=""
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?

#!/bin/bash
CURL='/usr/bin/curl'
RVMHTTP=""
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 $RVMHTTP > /tmp/rvm-installer
or:
url=”
content=”$(curl -sLI “$url” | grep HTTP/1.1 | tail -1 | awk {‘print $2′})”
if [ ! -z $content ] && [ $content -eq 200 ]
then
echo “valid url”
else
echo “invalid url”
fi
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.
