Why do I get
-bash: test: Permission denied
when I run
sudo echo "xyz" > test
The directory permissions are:
drwxr-xr-x 3 root root 4096 2014-08-05 16:26
I have no problem creating a file in the directory using sudo. But why can't I sudo echo into it?
This happens because you're only running the echo command as root. The output redirection is handled by your (non-root) shell. To avoid this, don't use the shell's redirect and use an actual command to handle the writing: tee. What you want to do can be done as so:
echo "xyz" | sudo tee test > /dev/null
(if you don't redirect the output, tee will output xyz to stdout, too)
