Here is a table of action arguments:
find-file. See Visiting.
When Emacs starts up, it displays the startup buffer in one window, and the buffer visiting file in another window (see Windows). If you supply more than one file argument, the displayed file is the last one specified on the command line; the other files are visited but their buffers are not shown.

file is visited in a single window if one file argument was
supplied; with two file arguments, Emacs displays the files in two
different windows; with more than two file argument, Emacs displays
the last file specified in one window, plus a Buffer Menu in a
different window (see Several Buffers). To inhibit using the
Buffer Menu for this, change the variable
find-file, then go to line number linenum in it.

files, the current directory is the directory of the last file
