how to go to line #23:

jump to line 23 on startup:
vim +23 filename

jump to line 23 in command mode:
23G
23gg

jump to line 23 in command mode:
:23

turn line numbering on:
:set nu

see also:
:help G
:help gg
:help range
:help 'nu'
:help +cmd

Yes, and as icing on the cake, a variation on this one: how to go to a
specific line and column:

" Go to line and column
function GoTo(line, column)
exe min([line("$"), a:line]) "| normal" a:column . "|"
endfunction

see
:help [range]
" a naked range goes to the line(s) mentioned
:help bar
" to go to a certain column
:help min()
" this function takes only a List or a Dictionary as argument

That's a good answer. The more modern version is to use -c like this:

vim -c :23 filename

Up to ten -c commands can be given, each with an ex mode command. Note
it may need quotes from the shell:

vim -c ':normal 23G' filename

I have a script that I use where I consider the filename to be sensitive
and I don't want it to appear in `ps` output. To invoke vim to edit that
file from script I use a temporary tags file. One could (but probably
would find it too cumbersome) use a method like that to go to line 23.

Here's the bit of sh script I use:

case "$mode" in
# ...
edit) tmp=tags
printf "main\t%s\t1\n" "$name" > $tmp
vim -t main
rc=$?
rm $tmp
exit $rc
;;
# ...
esac

In the 'tags' file I create, the three columns are tagname, filename,
and line number. (In typical 'tags' files the third column is a search
pattern, not a line number. Typically they also have multiple lines with
separate entries.) I then invoke vim with the tag name.

I bring it up in case this isn't going to be cumbersome and might be
something that helps your use case:

vim -c ':set tags=/some/shared/tags/file' -t tagname

You don't need a vim function to do that. You can run normal from the
command line. Go to line 23 column 45:

vim -c ':normal 23G45|' filename
