On Ubuntu, in what kind of situations, if any, running a command as a non-root
to access a file/folder or create/delete a file/folder using sudo
may result in "permission denied"
while running the same command as root
user would succeed? The user is assumed to be a sudoer, of course.
Practical example on Ubuntu 12: I've got this directory in /
with root:root
ownership and drwxr-xr-x
permissions and I tried sudo date > file
while in it as well as sudo date | tee file
but got the same
-bash: file: Permission denied
in both cases. Sure enough, there're no problems if I'm root
. This is quite frustrating.
