[Bug 1024536] [NEW] sudo piping

[Ohadcn]

Public bug reported:

i don't know if it is a bug or the OS should behave like that, but i would prefer it other way.
when i run a command as sudo and pipe it to another command or to a file, the command piped as normal user, when i typed

ohad at comp1:~$ sudo echo 10 > /proc/sys/vm/swappiness
bash: /proc/sys/vm/swappiness: Permission denied
ohad at comp1:~$ sudo echo firefox | apt-get install 
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
ohad at comp1:~$
