In reply to Parijatha Kumar. Did you try su -c 'cat hosts >> /etc/hosts'

In reply to Parijatha Kumar. You can do the following: cat hosts | sudo tee /etc/hosts tee (which is executed with sudo rights) will write the output to /etc/hosts and print it to standard out.

Be careful, Examples 4 and 11 are winners of the “Useless use of cat award,” which is often the case when you pipe cat output to another command.

The following command does not work.
sudo cat hosts >> /etc/hosts.
That’s why. I do …
1) sudo su
2) cat hosts >> /etc/hosts
Is there a single command to achieve the result of the above two commands ?
