pipe password to `sudo` and other data to `sudo`ed command

Both of these commands work: (note the -S in sudo tells sudo to read the password from stdin). echo 'mypassword' | sudo -S tee -a /etc/test.txt &> /dev/null echo -e '\nsome\nmore\ntext' | sudo tee -a /etc/test.txt &> /dev/null Now I would like to combine the two, i.e. achieve everything in just one line. But, of course, something like this doesn't work: echo -e '\nsome\nmore\ntext' | echo 'mypassword' | sudo -S tee -a /etc/test.txt &> /dev/null What would work? Thanks:) - Loady PS: Minor unrelated question: is 1> identical to > ? I believe they are..
