how to open a new file in an existing Vim window from the terminal

Question

I would like to type in a terminal:

openInVim file.txt

And it will open the file in my vim unique instance

For example if I type:

openInVim file1.txt
# do some stuff
openInVim file2.txt

I want to have one vim open with the two files load

How can I do that?

EDIT : I don't want open two files at the same time from the terminal I want to open a file in a single instance of vim from multiple terminal

Updated question - how to open a new file in an existing Vim window from the terminal (if i understand correctly).

Use the --remote option:

$ gvim file1.txt
$ gvim --remote file2.txt

See http://vim.wikia.com/wiki/Open_file_in_already_running_vim_from_elsewhere for details.

Original question - Here's how you open 2 files from the terminal in a single Vim window (I'm assuming here that "openInVim" is actually the vim or gvim command).

Open 2 files in 2 buffers:

openInVim file1.txt file2.txt

Open 2 files in 2 tabs:

openInVim -p file1.txt file2.txt

Open 2 files in split window:

openInVim -o file1.txt file2.txt

Open 2 files in vertically split window:

openInVim -O file1.txt file2.txt

and of course, all of this works with more than 2 files.
