For reference, some statically-linked shells on my system:
2288K /bin/bash-static (per manual, "too big and too slow")
1936K /bin/busybox-static (including tools not just the shell)
192K /usr/lib/klibc/bin/mksh
2456K zsh-static
For comparison, some dynamically-linked binaries (some old) 804K ./bin/bash-3.2
888K ./bin/bash-4.0
908K ./bin/bash-4.1
956K ./bin/bash-4.2
1016K ./bin/bash-4.3
1092K ./bin/bash-4.4
1176K ./bin/bash-5.0
1208K ./bin/bash-5.1
1236K /bin/bash (5.2)
124K /bin/dash
1448K /bin/ksh93 (fattest when excluding libc!)
292K /bin/mksh
144K /bin/posh
424K /bin/yash
848K /bin/zsh
(The reason I don't have static binaries handy is because they no longer run on modern systems. As long as you aren't using shitty libraries, dynamic binaries are more portable and reliable, contrary to internet "wisdom".)
