After writing my own test[0] I checked and sbase already has test. I'm
including a patch to remove test from the TODO. I also noticed that
sbase's test handles a few specific cases incorrectly (documentation
at [1]).
test ! = foo
When there are 3 arguments and the second is a valid binary primary
test should perform that binary test. Only if the second argument is
not a valid binary primary and the first is ! should test negate the
two argument test. I've attached a patch that should fix this.
test ! ! !
test ! ! ! !
When there are 3 arguments and the second is not a valid primary and
the first is !, test should return the negation of the remaining two
argument test. In this case sbase's test works correctly for ! and ! !
but fails afterwards as it's not recursive. I don't yet have a patch
for this but I'm working on one.
Then again both of these areas may be places in which worse is better.

sbase - suckless unix tools
===========================
sbase is a collection of unix tools that are inherently portable
across UNIX and UNIX-like systems.
The following programs are currently implemented:
basename
cal
cat
chgrp
chmod
chown
chroot
cksum
cmp
col
cols
comm
cp
cut
date
dirname
du
echo
env
expand
expr
false
fold
grep
head
hostname
kill
ln
ls
md5sum
mkdir
mkfifo
mktemp
mv
nice
nl
nohup
paste
printenv
printf
pwd
readlink
renice
rm
rmdir
sleep
setsid
sort
split
sponge
strings
sync
tail
tar
tee
test
touch
tr
true
tty
uudecode
uuencode
uname
unexpand
uniq
unlink
seq
sha1sum
sha256sum
sha512sum
wc
xargs
yes
sbase is mostly following POSIX but we deviate wherever we think it is
appropriate.
The complement of sbase is ubase[1] which is Linux-specific and
provides all the non-portable tools. Together they are intended to
form a base system similar to busybox but much smaller and suckless.
Building
--------
To build sbase, simply type make. You may have to fiddle with
config.mk depending on your system.
You can also build sbase-box, which generates a single binary
containing all the required tools. You can then symlink the
individual tools to sbase-box.
Ideally you will want to statically link sbase. If you are on Linux
we recommend using musl-libc[2].
Portability
-----------
sbase has been compiled on a variety of different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.
sbase also compiles and runs on minix3 with slight modifications.
They do not provide mmap()/munmap() so you need to use minix_mmap()
and minix_munmap() respectively.
Various combinations of operating systems and architectures have also
been built.
You can build sbase with gcc, clang, tcc, nwcc and pcc.
