tips

• show file name only

  $ rg --hidden 'alias ping' --no-heading --files-with-matches
  alias.d/utils
  

• in vimgrep format

  $ rg --hidden 'alias ping' --no-heading
  alias.d/utils:13:  alias ping='/sbin/ping --apple-time -v'
  # or
  $ rg 'alias ping' --no-heading --line-number --with-filename
  alias.d/utils:13:  alias ping='/sbin/ping --apple-time -v'
  
  $ rg --hidden 'alias ping' --vimgrep
  alias.d/utils:13:3:  alias ping='/sbin/ping --apple-time -v'
