vim -Nu NONE

# Verbose messages.
# -V[N]     Verbose.  Sets the 'verbose' option to [N] (default: 10).
#         Messages will be given for each file that is ":source"d and
#         for reading or writing a viminfo file.  Can be used to find
#         out what is happening upon startup and exit.  {not in Vi}
#         Example:
#             vim -V
#             vim -V8 foobar

# -V[N]{filename}
#         Like -V and set 'verbosefile' to {filename}.  The result is
#         that messages are not displayed but written to the file
#         {filename}.  {filename} must not start with a digit.
#         Example:
#             vim -V20vimlog foobar

Command line options

Option	Description
`+`	Position cursor on the last line.
`+num`	Position the cursor on line `num`.
`+command`	Same as `-c command`.
`-c command`	Execute `command` after the first file has been loaded (after it's read, autocommands and modelines for it have been processed).
`--cmd command`	Execute `command` before processing any vimrc file. Otherwise it acts like `-c command`.
`-t TAG`	Look up TAG, make the current file the file associated with the tag, and run the associated command.
`-q [errorfile]`	QuickFix mode. Read `errorfile` and display the first error. If `errorfile` is absent, uses the errorfile option instead.
`-S vimscript_file`	Equivalent to `-c "source vimscript_file"`. Handy for loading session files.
`-s vimscript_file`	Equivalent to `-c "source! vimscript_file"`. Since it uses `source!`, the characters in the file are interpreted as if you had typed them. After EOF, reads further characters from the keyboard.
`g`	Start in GUI mode.
`-e -s`	Batch mode as Ex. Silences most prompts, messages (including echo), warnings and errors. Prints the results of the following commands to stdout— :print, :list, :number, :set. If `verbose` is non-zero, prints messages to stderr. `term` and `$TERM` are ignored. Initializations, except those from `-u` are skipped.
`-b`	Binary mode.
`-l`	Lisp mode.
`-d`	Diff mode (like vimdiff)
`-V[N]`	Verbose mode. `N` defaults to 10. e.g. `-V` or `-V4`.
`-V[N]fname`	e.g. `-V20vimlog`. Like setting `-V[N]` and the 'verbosefile' option. Obviously, `fname` can't begin with a digit.
`-D`	Debugging mode. Enter debug-mode when running the first command from a script.
`-Z`	Restricted mode.
`-o[N]`	Open files in `N` horizontally split windows. If `N` is absent, it defaults to the number of files specified on the command line.
`-O[N]`	Open files in `N` vertically split windows. If `N` is absent, it defaults to the number of files specified on the command line.
`-p[N]`	Open files in `N` tab pages. If `N` is absent, it defaults to the number of files specified on the command line.
`--nofork`	Don't fork in GUI mode.
`--noplugin`	Don't load plugins. Resets the 'loadplugins' option. See also `-u`.
`-u vimrc`	Use `vimrc` for initialization. Most other initializations are skipped; see initialization. `vimrc` supports some special values. `NONE` skips all initializations from files include gvimrc and also does not load any plugins. `NORC` is like `NONE` but loads plugins.
`-U vimrc`	Use `gvimrc` for GUI initialization instead of other GUI initialization files. If set to `NONE`, skips GUI initialization from files.
`-w {scriptout}`	Record (append) all the characters you type into the file `scriptout`. You can later use that file with `:source`.
`-W {scriptout}`	Like `-w` but overwrite the file rather than append.
`-i viminfo`	Use `viminfo` as the viminfo-file. If set to `NONE`, then neither reads or writes viminfo regardless of the 'viminfo' option.
Triggers the	SourcePre

When you want to reduce accesses to the disk (e.g., for a laptop), don't use "-n", but set 'updatetime' and 'updatecount' to very big numbers, and type ":preserve" when you want to save your work. This way you keep the possibility for crash recovery.
