Possible Duplicate:Redirecting stdout to a file you don't have write permission on I'm new i'm trying to learn shell scripting. Is there a way to force a concatenation and override the privileges doing the following one line command?read domain; echo 127.0.1.1     $domain  >>  /etc/hostsWhat i'm trying to do is just create a simple script to type in the domain and then add it to my hosts file for development. Since my hosts file has restrictive permissions (even though i'm the only user with sudo powers) it won't let go.The ideal output would just do the following:127.0.0.1  foo.l
sudo here-document / concatenation?
shell script
Can't. >> is interpreted by the shell, so the sudo command effectively ends before that.However, you could try read domain; echo 127.0.1.1    $domain   | sudo tee --append /etc/hosts and see if that works as needed.
