Bash functions that execute commands on your behalf should append them to the history (see line 11)

bashrc_snippet.sh

gf() {
  local file
  if type batcat >/dev/null 2>&1; then
    file="$(git ls-files | fzf --preview 'batcat --color=always --wrap never --terminal-width $COLUMNS {}' --preview-window=right:60%)"
  else
    file="$(git ls-files | fzf --preview 'cat {}' --preview-window=right:60%)"
  fi
  if [ -n "$file" ]; then
    echo ${EDITOR:-vim} "$file"
    # vvvvvvvv It's more useful to have "vim [file]" in your history than just a "gf".
    history -s "${EDITOR:-vim} \"$file\""
    ${EDITOR:-vim} "$file"
  fi
}
