Opening a list of files in split windows

To open a list of files in split windows, we can use the -o and -O flags:

# Opens files in horizontal splits
vim -o file1 file2 file3

# The same, but with vertical splits
vim -O file1 file2 file3

Likewise, the -n flag can be used to open files in a tab each.

See :help -o for more information.
