How do you open a file from within Vim?

问题

I know how to open a file in vim from a terminal command line (vim fileName). What I can't figure out is how to open a file when I'm already within Vim. I tried :r fileName, but that appears to read (or append) the file into the unsaved buffer I have open. It creates a new file, because when I try to write it with :w, it asks for a filename.

回答1:

:e <filename>

or

:Ex <directory>

lets you browse for the file from the given directory.

:Ex on its own will open the pwd.

:enew

will create an empty buffer.

回答2:

this vim command you won't forget:

:Sex

if you want to point to certain dir, then :Sex <dir>

回答3:

Also, to open multiple files (or just one, so I tend to use this for opening a single file, since :e fails to open multiple files)

:n file1 file2

:n resets the argument list so it is as if you had entered them on the command line (so commands like :rew will work with this list), but :e does not.
