32 .SH DESCRIPTION | |
33 .B Vim | |
34 is a text editor that is upwards compatible to Vi. | |
35 It can be used to edit all kinds of plain text. | |
36 It is especially useful for editing programs. | |
37 .PP | |
38 There are a lot of enhancements above Vi: multi level undo, | |
39 multi windows and buffers, syntax highlighting, command line | |
40 editing, filename completion, on-line help, visual selection, etc.. | |
41 See ":help vi_diff.txt" for a summary of the differences between | |
42 .B Vim | |
43 and Vi. | |
44 .PP | |
45 While running | |
46 .B Vim | |
47 a lot of help can be obtained from the on-line help system, with the ":help" | |
48 command. | |
49 See the ON-LINE HELP section below. | |
50 .PP | |
51 Most often | |
52 .B Vim | |
53 is started to edit a single file with the command | |
54 .PP | |
55 vim file | |
56 .PP | |
57 More generally | |
58 .B Vim | |
59 is started with: | |
60 .PP | |
61 vim [options] [filelist] | |
62 .PP | |
63 If the filelist is missing, the editor will start with an empty buffer. | |
64 Otherwise exactly one out of the following four may be used to choose one or | |
65 more files to be edited. | |
66 .TP 12 | |
67 file .. | |
68 A list of filenames. | |
69 The first one will be the current file and read into the buffer. | |
70 The cursor will be positioned on the first line of the buffer. | |
71 You can get to the other files with the ":next" command. | |
216 | 72 To edit a file that starts with a dash, precede the filelist with "\-\-". |
7 | 73 .TP |
216 | 74 \- |
7 | 75 The file to edit is read from stdin. Commands are read from stderr, which |
76 should be a tty. | |
77 .TP | |
216 | 78 \-t {tag} |
7 | 79 The file to edit and the initial cursor position depends on a "tag", a sort |
80 of goto label. | |
81 {tag} is looked up in the tags file, the associated file becomes the current | |
82 file and the associated command is executed. | |
83 Mostly this is used for C programs, in which case {tag} could be a function | |
84 name. | |
85 The effect is that the file containing that function becomes the current file | |
86 and the cursor is positioned on the start of the function. | |
810 | 87 See ":help tag\-commands". |
7 | 88 .TP |
216 | 89 \-q [errorfile] |
7 | 90 Start in quickFix mode. |
91 The file [errorfile] is read and the first error is displayed. | |
92 If [errorfile] is omitted, the filename is obtained from the 'errorfile' | |
93 option (defaults to "AztecC.Err" for the Amiga, "errors.err" on other | |
94 systems). | |
95 Further errors can be jumped to with the ":cn" command. | |
96 See ":help quickfix". | |
97 .PP | |
98 .B Vim | |
99 behaves differently, depending on the name of the command (the executable may | |
100 still be the same file). | |
101 .TP 10 | |
102 vim | |
103 The "normal" way, everything is default. | |
104 .TP | |
105 ex | |
106 Start in Ex mode. | |
107 Go to Normal mode with the ":vi" command. | |
216 | 108 Can also be done with the "\-e" argument. |

112 Can also be done with the "\-R" argument. |
7 | 113 .TP |
114 gvim gview | |
115 The GUI version. | |
116 Starts a new window. | |
216 | 117 Can also be done with the "\-g" argument. |
7 | 118 .TP |
119 evim eview | |
120 The GUI version in easy mode. | |
121 Starts a new window. | |
216 | 122 Can also be done with the "\-y" argument. |
7 | 123 .TP |
124 rvim rview rgvim rgview | |
125 Like the above, but with restrictions. It will not be possible to start shell | |
126 commands, or suspend | |
127 .B Vim. | |
216 | 128 Can also be done with the "\-Z" argument. |
7 | 129 .SH OPTIONS |
130 The options may be given in any order, before or after filenames. | |
131 Options without an argument can be combined after a single dash. | |
132 .TP 12 | |
133 +[num] | |
134 For the first file the cursor will be positioned on line "num". | |
135 If "num" is missing, the cursor will be positioned on the last line. | |
136 .TP | |
137 +/{pat} | |
6530 | 138 For the first file the cursor will be positioned in the line with the |
7 | 139 first occurrence of {pat}. |
810 | 140 See ":help search\-pattern" for the available search patterns. |
7 | 141 .TP |
142 +{command} | |
143 .TP | |

145 {command} will be executed after the first file has been read. |
7 | 146 {command} is interpreted as an Ex command. |
147 If the {command} contains spaces it must be enclosed in double quotes (this | |
148 depends on the shell that is used). | |
149 Example: Vim "+set si" main.c | |
150 .br | |
216 | 151 Note: You can use up to 10 "+" or "\-c" commands. |
7 | 152 .TP |
216 | 153 \-S {file} |
7 | 154 {file} will be sourced after the first file has been read. |
216 | 155 This is equivalent to \-c "source {file}". |
156 {file} cannot start with '\-'. | |
157 If {file} is omitted "Session.vim" is used (only works when \-S is the last | |
7 | 158 argument). |
159 .TP | |
216 | 160 \-\-cmd {command} |
161 Like using "\-c", but the command is executed just before | |
7 | 162 processing any vimrc file. |
216 | 163 You can use up to 10 of these commands, independently from "\-c" commands. |
7 | 164 .TP |
216 | 165 \-A |
7 | 166 If |
167 .B Vim | |
168 has been compiled with ARABIC support for editing right-to-left | |
169 oriented files and Arabic keyboard mapping, this option starts | |
170 .B Vim | |
171 in Arabic mode, i.e. 'arabic' is set. Otherwise an error | |
172 message is given and | |
173 .B Vim | |
174 aborts. | |
175 .TP | |
216 | 176 \-b |
7 | 177 Binary mode. |
178 A few options will be set that makes it possible to edit a binary or | |
179 executable file. | |
180 .TP | |
216 | 181 \-C |
7 | 182 Compatible. Set the 'compatible' option. |
183 This will make | |
184 .B Vim | |
185 behave mostly like Vi, even though a .vimrc file exists. | |
186 .TP | |
216 | 187 \-d |
7 | 188 Start in diff mode. |
1698 | 189 There should be two, three or four file name arguments. |
7 | 190 .B Vim |
191 will open all the files and show differences between them. | |
192 Works like vimdiff(1). | |
193 .TP | |
216 | 194 \-d {device} |
7 | 195 Open {device} for use as a terminal. |
196 Only on the Amiga. | |
197 Example: | |
198 "\-d con:20/30/600/150". | |
199 .TP | |
216 | 200 \-D |
7 | 201 Debugging. Go to debugging mode when executing the first command from a |
202 script. | |
203 .TP | |
216 | 204 \-e |
7 | 205 Start |
206 .B Vim | |
207 in Ex mode, just like the executable was called "ex". | |
208 .TP | |
216 | 209 \-E |
7 | 210 Start |
211 .B Vim | |
212 in improved Ex mode, just like the executable was called "exim". | |
213 .TP | |
216 | 214 \-f |
7 | 215 Foreground. For the GUI version, |
216 .B Vim | |
217 will not fork and detach from the shell it was started in. | |
218 On the Amiga, | |
219 .B Vim | |
220 is not restarted to open a new window. | |
221 This option should be used when | |
222 .B Vim | |
223 is executed by a program that will wait for the edit | |
224 session to finish (e.g. mail). | |
225 On the Amiga the ":sh" and ":!" commands will not work. | |
226 .TP | |
216 | 227 \-\-nofork |
7 | 228 Foreground. For the GUI version, |
229 .B Vim | |
230 will not fork and detach from the shell it was started in. | |
231 .TP | |
216 | 232 \-F |
7 | 233 If |
234 .B Vim | |
235 has been compiled with FKMAP support for editing right-to-left | |
236 oriented files and Farsi keyboard mapping, this option starts | |
237 .B Vim | |
238 in Farsi mode, i.e. 'fkmap' and 'rightleft' are set. | |
239 Otherwise an error message is given and | |
240 .B Vim | |
241 aborts. | |
242 .TP | |
216 | 243 \-g |
7 | 244 If |
245 .B Vim | |
246 has been compiled with GUI support, this option enables the GUI. | |
247 If no GUI support was compiled in, an error message is given and | |
248 .B Vim | |
249 aborts. | |
250 .TP | |
216 | 251 \-h |
7 | 252 Give a bit of help about the command line arguments and options. |
253 After this | |
254 .B Vim | |
255 exits. | |
256 .TP | |
216 | 257 \-H |
7 | 258 If |
259 .B Vim | |
260 has been compiled with RIGHTLEFT support for editing right-to-left | |
261 oriented files and Hebrew keyboard mapping, this option starts | |
262 .B Vim | |
263 in Hebrew mode, i.e. 'hkmap' and 'rightleft' are set. | |
264 Otherwise an error message is given and | |
265 .B Vim | |
266 aborts. | |
267 .TP | |
216 | 268 \-i {viminfo} |
17758 | 269 Specifies the filename to use when reading or writing the viminfo file, |
7 | 270 instead of the default "~/.viminfo". |
271 This can also be used to skip the use of the .viminfo file, by giving the name | |
272 "NONE". | |
273 .TP | |
216 | 274 \-L |
275 Same as \-r. | |
7 | 276 .TP |
216 | 277 \-l |
7 | 278 Lisp mode. |
279 Sets the 'lisp' and 'showmatch' options on. | |
280 .TP | |
216 | 281 \-m |
7 | 282 Modifying files is disabled. |
283 Resets the 'write' option. | |
284 You can still modify the buffer, but writing a file is not possible. | |
285 .TP | |
216 | 286 \-M |
7 | 287 Modifications not allowed. The 'modifiable' and 'write' options will be unset, |
288 so that changes are not allowed and files can not be written. Note that these | |
289 options can be set to enable making modifications. | |
290 .TP | |
216 | 291 \-N |
17758 | 292 No-compatible mode. Resets the 'compatible' option. |
7 | 293 This will make |
294 .B Vim | |
295 behave a bit better, but less Vi compatible, even though a .vimrc file does | |
296 not exist. | |
297 .TP | |
216 | 298 \-n |
7 | 299 No swap file will be used. |
300 Recovery after a crash will be impossible. | |
301 Handy if you want to edit a file on a very slow medium (e.g. floppy). | |
302 Can also be done with ":set uc=0". | |
303 Can be undone with ":set uc=200". | |
304 .TP | |
216 | 305 \-nb |
7 | 306 Become an editor server for NetBeans. See the docs for details. |
307 .TP | |
216 | 308 \-o[N] |
7 | 309 Open N windows stacked. |
310 When N is omitted, open one window for each file. | |
311 .TP | |
216 | 312 \-O[N] |
7 | 313 Open N windows side by side. |
314 When N is omitted, open one window for each file. | |
315 .TP | |
802 | 316 \-p[N] |
317 Open N tab pages. | |
318 When N is omitted, open one tab page for each file. | |
319 .TP | |
216 | 320 \-R |
7 | 321 Read-only mode. |
322 The 'readonly' option will be set. | |

323 You can still edit the buffer, but will be prevented from accidentally |
7 | 324 overwriting a file. |
325 If you do want to overwrite a file, add an exclamation mark to the Ex command, | |
326 as in ":w!". | |
12559 | 327 The \-R option also implies the \-n option (see above). |
7 | 328 The 'readonly' option can be reset with ":set noro". |
329 See ":help 'readonly'". | |
330 .TP | |
216 | 331 \-r |
7 | 332 List swap files, with information about using them for recovery. |
333 .TP | |
216 | 334 \-r {file} |
7 | 335 Recovery mode. |
336 The swap file is used to recover a crashed editing session. | |
337 The swap file is a file with the same filename as the text file with ".swp" | |
338 appended. | |
339 See ":help recovery". | |
340 .TP | |
216 | 341 \-s |
342 Silent mode. Only when started as "Ex" or when the "\-e" option was given | |
343 before the "\-s" option. | |
7 | 344 .TP |
216 | 345 \-s {scriptin} |
7 | 346 The script file {scriptin} is read. |
347 The characters in the file are interpreted as if you had typed them. | |
348 The same can be done with the command ":source! {scriptin}". | |
349 If the end of the file is reached before the editor exits, further characters | |
350 are read from the keyboard. | |
351 .TP | |
216 | 352 \-T {terminal} |
7 | 353 Tells |
354 .B Vim | |
355 the name of the terminal you are using. | |
356 Only required when the automatic way doesn't work. | |

357 Should be a terminal known to |
7 | 358 .B Vim |
359 (builtin) or defined in the termcap or terminfo file. | |
360 .TP | |
216 | 361 \-u {vimrc} |
7 | 362 Use the commands in the file {vimrc} for initializations. |
363 All the other initializations are skipped. | |
364 Use this to edit a special kind of files. | |
365 It can also be used to skip all initializations by giving the name "NONE". | |
366 See ":help initialization" within vim for more details. | |
367 .TP | |
216 | 368 \-U {gvimrc} |
7 | 369 Use the commands in the file {gvimrc} for GUI initializations. |
370 All the other GUI initializations are skipped. | |
371 It can also be used to skip all GUI initializations by giving the name "NONE". | |
810 | 372 See ":help gui\-init" within vim for more details. |
7 | 373 .TP |
216 | 374 \-V[N] |
7 | 375 Verbose. Give messages about which files are sourced and for reading and |
376 writing a viminfo file. The optional number N is the value for 'verbose'. | |
377 Default is 10. | |
378 .TP | |
216 | 379 \-v |
7 | 380 Start |
381 .B Vim | |
382 in Vi mode, just like the executable was called "vi". This only has effect | |
383 when the executable is called "ex". | |
384 .TP | |
216 | 385 \-w {scriptout} |
7 | 386 All the characters that you type are recorded in the file |
387 {scriptout}, until you exit | |
388 .B Vim. | |
216 | 389 This is useful if you want to create a script file to be used with "vim \-s" or |
7 | 390 ":source!". |
391 If the {scriptout} file exists, characters are appended. | |
392 .TP | |
216 | 393 \-W {scriptout} |
394 Like \-w, but an existing file is overwritten. | |
7 | 395 .TP |
216 | 396 \-x |
33 | 397 Use encryption when writing files. Will prompt for a crypt key. |
7 | 398 .TP |
216 | 399 \-X |
7 | 400 Don't connect to the X server. Shortens startup time in a terminal, but the |
401 window title and clipboard will not be used. | |
402 .TP | |
216 | 403 \-y |
7 | 404 Start |
405 .B Vim | |
406 in easy mode, just like the executable was called "evim" or "eview". | |

408 .B Vim | |
409 behave like a click-and-type editor. | |
410 .TP | |
216 | 411 \-Z |
7 | 412 Restricted mode. Works like the executable starts with "r". |
413 .TP | |
216 | 414 \-\- |
7 | 415 Denotes the end of the options. |
416 Arguments after this will be handled as a file name. | |
216 | 417 This can be used to edit a filename that starts with a '\-'. |

216 | 419 \-\-echo\-wid |
33 | 420 GTK GUI only: Echo the Window ID on stdout. |
7 | 421 .TP |
216 | 422 \-\-help |
423 Give a help message and exit, just like "\-h". | |
7 | 424 .TP |
216 | 425 \-\-literal |
33 | 426 Take file name arguments literally, do not expand wildcards. This has no |
427 effect on Unix where the shell expands wildcards. | |

7 | 441 Connect to a Vim server and send {keys} to it. |
442 .TP | |
216 | 443 \-\-remote\-silent |
444 As \-\-remote, but without the warning when no server is found. | |
7 | 445 .TP |
216 | 446 \-\-remote\-wait |
447 As \-\-remote, but Vim does not exit until the files have been edited. | |
7 | 448 .TP |
216 | 449 \-\-remote\-wait\-silent |

216 | 455 \-\-servername {name} |
7 | 456 Use {name} as the server name. Used for the current Vim, unless used with a |
216 | 457 \-\-remote argument, then it's the name of the server to connect to. |
7 | 458 .TP |
216 | 459 \-\-socketid {id} |
7 | 460 GTK GUI only: Use the GtkPlug mechanism to run gvim in another window. |

546 Note that a number of things that may be regarded as bugs by some, are in fact | |
547 caused by a too-faithful reproduction of Vi's behaviour. | |
548 And if you think other things are bugs "because Vi does it differently", | |
549 you should take a closer look at the vi_diff.txt file (or type :help | |
550 vi_diff.txt when in Vim). | |
551 Also have a look at the 'compatible' and 'cpoptions' options. |
