Sends both stdout and stderr to the pipe which captures the data in the file 'out.test' and sends to stdout of tee (likely /dev/tty unless redirected). Works on Bourne, Korn and Bash shells.

bash or tcsh redirect both to stdout and to a file

When plumbers use pipes, they sometimes need a T-joint. The Unix equivalent to this is 'tee'. The -a flag tells 'tee' to append to the file, rather than clobbering it.

Tested on bash and tcsh.

echo "foo bar" | sudo tee -a /path/to/some/file

Add a line to a file using sudo

This is the solution to the common mistake made by sudo newbies, since

sudo echo "foo bar" >> /path/to/some/file

does NOT add to the file as root.

Alternatively,

sudo echo "foo bar" > /path/to/some/file

should be replaced by

echo "foo bar" | sudo tee /path/to/some/file

And you can add a >/dev/null in the end if you're not interested in the tee stdout :

echo "foo bar" | sudo tee -a /path/to/some/file >/dev/null
