This looks smart

gem update `gem list | cut -d ' ' -f 1`

Though on the bash prompt, it works fine on Mac OS X / OS X / macOS / …, it does not work nice as an alias.

You can get it to work with difficult escaping (or nesting).

But it is easier to escape this:

gem update $(gem list | cut -d ' ' -f 1)

Escaped, it comes down to:

alias "gem-update-all=gem update \$(gem list | cut -d ' ' -f 1)"
