Why does Debian not include POSIX-specified commands like bc and ed by default?
POSIX.1-2001 Utilities and POSIX.1-2008 Utilities both list the
commands "bc" and "ed" to be part of POSIX.
Yet, in a brand new Debian installation (version 10 for example),
these commands are missing by default:
bash: bc: command not found
bash: ed: command not found
Why does Debian not include these commands by default? Of course, I
can install them with "apt-get" and I did that.
apt-get install bc ed
The "bc" binary is only 87K in size. The entire package including the
man page and documentation is only 209K in size.
Similarly the "ed" binary is only 55K in size. The entire package is
only 93K in size.
What good reason is there not to include these tiny packages even
though they are specified in POSIX?
