¿Sabe brew o le importa que internet piense que pin
¿se ha eliminado? :-)
Mi brew (3.3.12, último commit 2022-01-26) no sabe nada al respecto. Desde man brew
pin installed_formula [...]
Pin the specified formula, preventing them from being upgraded when issuing the brew upgrade
formula command. See also unpin.
upgrade [options] [outdated_formula|outdated_cask ...]
Upgrade outdated casks and outdated, unpinned formulae using the same options they were
originally installed with, plus any appended brew formula options. If cask or formula are
specified, upgrade only the given cask or formula kegs (unless they are pinned; see pin, unpin).
La documentación parece estar a la par con la realidad ya que pude anclar, sacar la lista de anclados y desanclar:
+ > brew pin fzf
+ > brew list --pinned
fzf
+ > brew unpin fzf
+ > brew list --pinned
+ >
Si pin
es lo que quieres o necesitas es otra historia, pero los rumores de que pin
es eliminado son muy exagerados.
