Why does sudo not work with curl?

Question

I ran a command to download something with curl –

sudo curl roots.cx/get | sh

– and it threw a permission denied error. So I did sudo curl and I got the same error … why is that?

I was able to run the install command without curl, but I needed to sudo, so why does curl not work with sudo?

Are you sure the website was not returning the "permission denied" error, rather then Perl ? What variant of Linux are you using and is SELinux running ? — davidgo, Commented Feb 13, 2013 at 5:44

Use sudo after the pipe:

curl roots.cx/get | sudo sh

the get script involves some installation, requires sudo to run.

Alternatively you can use:

sudo \curl roots.cx/get | sh
