# Builtins: coreutils

This is an optional package that covers some of the basic packages you'd
expect to find in your POSIX environment. It it not aimed at being a
complete like for like rewrite of GNU coreutils (for example) nor will
it offer the same degree of optimisations. So if you are running on a
POSIX environment then it is recommend you leave this package disabled
(as it is on non-Windows systems by default). If you are running Windows
and you want better compatibility with GNU coreutils or performance is a
major concern then I would recommend you install either WSL[1], Cygwin[2]
or MinGW[3].
