How to open files in vertically/horizontal split windows in Vim from the command line

Question

There must be a way, something like this:

vim -[option] <file-list>

to open files from command prompt and not from within Vim.

• split windows vertically or/and horizontally
• in separate tabs

Answer 1

I'm assuming you mean from the command line. From vim --help:

-o[N]                Open N windows (default: one for each file)
-O[N]                Like -o but split vertically

So type this to open files split horizontally, for example:

vim -o file1.txt file2.txt file3.txt

Answer 2

Ctrl-W s for horizontal splitting

Ctrl-W v for vertical splitting

Ctrl-w q to close one

Answer 3

While running vim:

1. :sp filename for a horizontal split
2. :vsp filename or :vs filename for a vertical split

Answer 4

another interested trick is the CLI -p argument - which opens them in separate tabs for recent versions of vim and gvim.

gvim -p file1.txt file2.txt

Answer 5

Another useful trick that I just found out, is that you can use wildcards in the filelist to open multiple files. Say you want to open file1.txt, file2.txt, and file3.txt all in separate tabs but don't feel like typing that all out you can just do:

vim -p file*

I frequently find myself needing to open a lot of files with a similar prefix, and this has been quite helpful
