找不到墙命令Debian

Question

The wall command does not seem to be on my Debian distro. Already updated packages and upgraded but still no wall command.

Whenever I do wall the output is

-bash: wall: command not found

Answer 1

It is part of the bsdutils package:

sudo apt-get install bsdutils
dpkg -L bsdutils

On my Debian7, for instance the listing shows
