Is there a shortcut to open vim and then jump to line ”num“ as ":num"?

Question

I used to search words in my code tree by grep -rn. And the output is just as below.

"{filename}:{num}:{line content}"

Sometimes I will to open the file with vim, and jump to the line num as below.

vim {filename} +{num}

But I would like to do those steps as below. Is there any shortcut?

vim {filename}:{num}

You could create a shell function to do this, say, vimn:

vimn () {
  case $1 in
  (*:[1-9]*) vim "${1%:*}" +"${1##*:}";;
  (*)        vim "$@"
  esac
}

This assumes a Bourne-type shell (sh, bash, ksh, zsh, ...). There are ways to make this work for a function named vim as well, but I prefer to avoid overloading command names.

EDIT: make this work for vimn hello:world:42 -> open hello:world at line 42.
