Aliases and functions are absolutely useless any time the exec system
call is involved, which is more common than you might think. Take, for
example, using the filter (!) command in vim. Sure functions will
work, but not aliases. Now consider exec.Command() in Go. You can
forget about your shell functions because Go has no way to resolve them,
and it shouldn’t.
Shortcut scripts are also easier to share and include into containers as independent POSIX shell, or to eventually replace with an actual binary so that they work on any OS, not just UNIX/Linux.
