This is a tracking issue for commands that we should implement as builtins in the Bun shell. Some of these are taken from GNU coreutils.

• cat
• touch
• mkdir
• cd
• echo
• pwd
• which
• rm
• mv
• ls
• exit
• true
• false
• cp
• timeout
• yes
• basename
• realpath
• dirname
• mktemp
• truncate
• head
• tail
• cut
• uniq
• seq
• sleep
• tee
• date
• sha1sum
• sha224sum
• sha256sum
• sha384sum
• sha512sum
• md5sum
• sort
• printenv
• env
• whoami
• who
• uptime

This is not an exhaustive list, we can add commands as we think it's a good idea to implement.

While these will already be generally available on most posix systems, having them in the Shell will also allow them to be readily available on Windows when using Bun Shell.
