alias not working after su?
 

Why doesn't alias work after I su to root?

$ alias foo='echo bar'
$ foo
bar

$ su
Password:

# alias foo='echo bar'
# foo
foo: Command not found.

Works fine on my system. What distro and shell are you using ("echo $0" before and after the su)?

Good on Ubuntu 14 series also.

The root shell is c-shell. Not bash.
Thanks for helping me figure this out!

alias foo 'echo bar'

works as expected.
