is it possible to run commands like this with sudo?

echo "ssh-rsa AAAAAAAA=" > /home/larz/.ssh/authorized_keys

the part of the command that needs sudo isn't the echo, but writing it to the file in another user's directory. as a result, this doesn't work:

% sudo echo "ssh-rsa AAAAAAAA=" > /home/larz/.ssh/authorized_keys
[zsh: permission denied: /home/larz/.ssh/authorized_keys]

thanks!

I'm not sure if you can do that directly, but if you put the command in a shell script and give it execute permissions, you should be able to add that to the sudoers file.

roddierod on bsdnexus gave a good solution, too. thanks.

sudo su?

What was the solution?

i just wanted a quick one-liner for the cli.

he gave this, but it's a bit longer than my ideal solution:

sudo sh -c 'echo "ssh-rsa AAAAAA=" > /home/larz/.ssh/authorized_keys'

Ah, now I understood what you meant... Most times I just do "sudo -s" and get a shell :P
