There is this however, reference to OSX 10.14.1, default bash terminal:
Both XUbuntu56 and I can learn from your expertise on this.
I have not copied and pasted the man pages but they do exist.
As you can see there is a manual AND a help entry for "true" and "false", do I take it the some shells, perhaps dash or ash, do not have these as builtins as it looks like I have both builtin and transient versions.
":" is builtin only so I assume that in POSIX this IS a requirement but the others are optional?

0store-secure-add
0STORE-SECURE-ADD(1)0STORE-SECURE-ADD(1)NAME
0store-secure-add -- add an implementation to the system cache
SYNOPSIS
0store-secure-add DIGEST
DESCRIPTION
This command imports the current directory into the system-wide shared Zero Install cache, as /var/cache/0install.net/implementa-
tions/DIGEST. This allows a program downloaded by one user to be shared with other users.
The current directory must contain a file called '.manifest' listing all the files to be added (in the format required by DIGEST), and this
file must have the given digest. If not, the import is refused. Therefore, it is only possible to add a directory to the cache if its name
matches its contents.
It is intended that it be safe to grant untrusted users permission to call this command with elevated privileges. To set this up, see
below.
SETTING UP SHARING
To enable sharing, the system administrator should follow these steps:
Create a new system user to own the cache:
adduser --system zeroinst
Create the shared directory, owned by this new user:
mkdir /var/cache/0install.net
chown zeroinst /var/cache/0install.net
Use visudo(8) to add these lines to /etc/sudoers:
Defaults>zeroinst env_reset,always_set_home
ALL ALL=(zeroinst) NOPASSWD: /usr/bin/0store-secure-add
Create a script called 0store-secure-add-helper in PATH to call it. This script must be executable and contain these two lines:
#!/bin/sh
exec sudo -S -u zeroinst /usr/bin/0store-secure-add "$@" < /dev/null
The other Zero Install programs will call this helper script automatically.

BUGS
This program is EXPERIMENTAL. It has not been audited. Do not use it yet in security-critial environments.
The env_reset line in sudoers may not be required. sudo(1) seems to do it automatically.
If sudo let us check whether we could call a command then we could switch to using it automatically, instead of needing to add the helper
script. Currently, sudo delays for one second and writes to auth.log if we try to use this system when it hasn't been set up.
