Consider the description for :

The history command can be used to retrieve commands you have previously typed in a shell.

However, fc and related variables FCEDIT and HISTSIZE exist in bash. There's no specific shell mentioned (which arguably might be implied to be ), but fc is POSIX utility and hist is used on Korn shell variants (which is very close to bash); considering that we don't have that big of a following for other shells, they still are available, and it would make sense to include that as tag synonym for .

As per terdon's comment on related question, which haven't gained much attention,

You are assuming that tags are rationally organized and inherit from each other. Unfortunately, neither of those is the case. But yes, we do want the pure history tag since bash-history isn't applicable t questions about zsh, sh, ksh, csh, fish etc., etc.

As I mentioned before, the portions involved with history mechanism occurs in other shells. Plus I think other shell users can figure out what works for bash and non-bash shell. So I'd say fc is a rational enough synonym.

    I don't see anything tagged as fc. In fact, I don't really think there's any need for an fc tag or a synonym to history. Is something actually using fc as a tag? Creating synonyms "Just because" is usually not a reason to create a synonym... – Thomas Ward Apr 21 '18 at 21:54
  • @ThomasWard Fair point, I guess. – Sergiy Kolodyazhnyy Apr 21 '18 at 22:12
