| 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. |
| 7 | 109 .TP |
| 110 view | |
| 111 Start in read-only mode. You will be protected from writing the files. Can | |
| 216 | 112 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 | |
| 216 | 144 \-c {command} |
| 7 | 145 {command} will be executed after the |
| 146 first file has been read. | |
| 147 {command} is interpreted as an Ex command. | |
| 148 If the {command} contains spaces it must be enclosed in double quotes (this | |
| 149 depends on the shell that is used). | |
| 150 Example: Vim "+set si" main.c | |
| 151 .br | |
| 216 | 152 Note: You can use up to 10 "+" or "\-c" commands. |
| 7 | 153 .TP |
| 216 | 154 \-S {file} |
| 7 | 155 {file} will be sourced after the first file has been read. |
| 216 | 156 This is equivalent to \-c "source {file}". |
| 157 {file} cannot start with '\-'. | |
| 158 If {file} is omitted "Session.vim" is used (only works when \-S is the last | |
| 7 | 159 argument). |
| 160 .TP | |
| 216 | 161 \-\-cmd {command} |
| 162 Like using "\-c", but the command is executed just before | |
| 7 | 163 processing any vimrc file. |
| 216 | 164 You can use up to 10 of these commands, independently from "\-c" commands. |
| 7 | 165 .TP |
| 216 | 166 \-A |
| 7 | 167 If |
| 168 .B Vim | |
| 169 has been compiled with ARABIC support for editing right-to-left | |
| 170 oriented files and Arabic keyboard mapping, this option starts | |
| 171 .B Vim | |
| 172 in Arabic mode, i.e. 'arabic' is set. Otherwise an error | |
| 173 message is given and | |
| 174 .B Vim | |
| 175 aborts. | |
| 176 .TP | |
| 216 | 177 \-b |
| 7 | 178 Binary mode. |
| 179 A few options will be set that makes it possible to edit a binary or | |
| 180 executable file. | |
| 181 .TP | |
| 216 | 182 \-C |
| 7 | 183 Compatible. Set the 'compatible' option. |
| 184 This will make | |
| 185 .B Vim | |
| 186 behave mostly like Vi, even though a .vimrc file exists. | |
| 187 .TP | |
| 216 | 188 \-d |
| 7 | 189 Start in diff mode. |
| 1698 | 190 There should be two, three or four file name arguments. |
| 7 | 191 .B Vim |
| 192 will open all the files and show differences between them. | |
| 193 Works like vimdiff(1). | |
| 194 .TP | |
| 216 | 195 \-d {device} |
| 7 | 196 Open {device} for use as a terminal. |
| 197 Only on the Amiga. | |
| 198 Example: | |
| 199 "\-d con:20/30/600/150". | |
| 200 .TP | |
| 216 | 201 \-D |
| 7 | 202 Debugging. Go to debugging mode when executing the first command from a |
| 203 script. | |
| 204 .TP | |
| 216 | 205 \-e |
| 7 | 206 Start |
| 207 .B Vim | |
| 208 in Ex mode, just like the executable was called "ex". | |
| 209 .TP | |
| 216 | 210 \-E |
| 7 | 211 Start |
| 212 .B Vim | |
| 213 in improved Ex mode, just like the executable was called "exim". | |
| 214 .TP | |
| 216 | 215 \-f |
| 7 | 216 Foreground. For the GUI version, |
| 217 .B Vim | |
| 218 will not fork and detach from the shell it was started in. | |
| 219 On the Amiga, | |
| 220 .B Vim | |
| 221 is not restarted to open a new window. | |
| 222 This option should be used when | |
| 223 .B Vim | |
| 224 is executed by a program that will wait for the edit | |
| 225 session to finish (e.g. mail). | |
| 226 On the Amiga the ":sh" and ":!" commands will not work. | |
| 227 .TP | |
| 216 | 228 \-\-nofork |
| 7 | 229 Foreground. For the GUI version, |
| 230 .B Vim | |
| 231 will not fork and detach from the shell it was started in. | |
| 232 .TP | |
| 216 | 233 \-F |
| 7 | 234 If |
| 235 .B Vim | |
| 236 has been compiled with FKMAP support for editing right-to-left | |
| 237 oriented files and Farsi keyboard mapping, this option starts | |
| 238 .B Vim | |
| 239 in Farsi mode, i.e. 'fkmap' and 'rightleft' are set. | |
| 240 Otherwise an error message is given and | |
| 241 .B Vim | |
| 242 aborts. | |
| 243 .TP | |
| 216 | 244 \-g |
| 7 | 245 If |
| 246 .B Vim | |
| 247 has been compiled with GUI support, this option enables the GUI. | |
| 248 If no GUI support was compiled in, an error message is given and | |
| 249 .B Vim | |
| 250 aborts. | |
| 251 .TP | |
| 216 | 252 \-h |
| 7 | 253 Give a bit of help about the command line arguments and options. |
| 254 After this | |
| 255 .B Vim | |
| 256 exits. | |
| 257 .TP | |
| 216 | 258 \-H |
| 7 | 259 If |
| 260 .B Vim | |
| 261 has been compiled with RIGHTLEFT support for editing right-to-left | |
| 262 oriented files and Hebrew keyboard mapping, this option starts | |
| 263 .B Vim | |
| 264 in Hebrew mode, i.e. 'hkmap' and 'rightleft' are set. | |
| 265 Otherwise an error message is given and | |
| 266 .B Vim | |
| 267 aborts. | |
| 268 .TP | |
| 216 | 269 \-i {viminfo} |
| 7 | 270 When using the viminfo file is enabled, this option sets the filename to use, |
| 271 instead of the default "~/.viminfo". | |
| 272 This can also be used to skip the use of the .viminfo file, by giving the name | |
| 273 "NONE". | |
| 274 .TP | |
| 216 | 275 \-L |
| 276 Same as \-r. | |
| 7 | 277 .TP |
| 216 | 278 \-l |
| 7 | 279 Lisp mode. |
| 280 Sets the 'lisp' and 'showmatch' options on. | |
| 281 .TP | |
| 216 | 282 \-m |
| 7 | 283 Modifying files is disabled. |
| 284 Resets the 'write' option. | |
| 285 You can still modify the buffer, but writing a file is not possible. | |
| 286 .TP | |
| 216 | 287 \-M |
| 7 | 288 Modifications not allowed. The 'modifiable' and 'write' options will be unset, |
| 289 so that changes are not allowed and files can not be written. Note that these | |
| 290 options can be set to enable making modifications. | |
| 291 .TP | |
| 216 | 292 \-N |
| 7 | 293 No-compatible mode. Reset the 'compatible' option. |
| 294 This will make | |
| 295 .B Vim | |
| 296 behave a bit better, but less Vi compatible, even though a .vimrc file does | |
| 297 not exist. | |
| 298 .TP | |
| 216 | 299 \-n |
| 7 | 300 No swap file will be used. |
| 301 Recovery after a crash will be impossible. | |
| 302 Handy if you want to edit a file on a very slow medium (e.g. floppy). | |
| 303 Can also be done with ":set uc=0". | |
| 304 Can be undone with ":set uc=200". | |
| 305 .TP | |
| 216 | 306 \-nb |
| 7 | 307 Become an editor server for NetBeans. See the docs for details. |
| 308 .TP | |
| 216 | 309 \-o[N] |
| 7 | 310 Open N windows stacked. |
| 311 When N is omitted, open one window for each file. | |
| 312 .TP | |
| 216 | 313 \-O[N] |
| 7 | 314 Open N windows side by side. |
| 315 When N is omitted, open one window for each file. | |
| 316 .TP | |
| 802 | 317 \-p[N] |
| 318 Open N tab pages. | |
| 319 When N is omitted, open one tab page for each file. | |
| 320 .TP | |
| 216 | 321 \-R |
| 7 | 322 Read-only mode. |
| 323 The 'readonly' option will be set. | |

324 You can still edit the buffer, but will be prevented from accidentally |
| 7 | 325 overwriting a file. |
| 326 If you do want to overwrite a file, add an exclamation mark to the Ex command, | |
| 327 as in ":w!". | |
| 12559 | 328 The \-R option also implies the \-n option (see above). |
| 7 | 329 The 'readonly' option can be reset with ":set noro". |
| 330 See ":help 'readonly'". | |
| 331 .TP | |
| 216 | 332 \-r |
| 7 | 333 List swap files, with information about using them for recovery. |
| 334 .TP | |
| 216 | 335 \-r {file} |
| 7 | 336 Recovery mode. |
| 337 The swap file is used to recover a crashed editing session. | |
| 338 The swap file is a file with the same filename as the text file with ".swp" | |
| 339 appended. | |
| 340 See ":help recovery". | |
| 341 .TP | |
| 216 | 342 \-s |
| 343 Silent mode. Only when started as "Ex" or when the "\-e" option was given | |
| 344 before the "\-s" option. | |
| 7 | 345 .TP |
| 216 | 346 \-s {scriptin} |
| 7 | 347 The script file {scriptin} is read. |
| 348 The characters in the file are interpreted as if you had typed them. | |
| 349 The same can be done with the command ":source! {scriptin}". | |
| 350 If the end of the file is reached before the editor exits, further characters | |
| 351 are read from the keyboard. | |
| 352 .TP | |
| 216 | 353 \-T {terminal} |
| 7 | 354 Tells |
| 355 .B Vim | |
| 356 the name of the terminal you are using. | |
| 357 Only required when the automatic way doesn't work. | |
| 358 Should be a terminal known | |
| 359 to | |
| 360 .B Vim | |
| 361 (builtin) or defined in the termcap or terminfo file. | |
| 362 .TP | |
| 216 | 363 \-u {vimrc} |
| 7 | 364 Use the commands in the file {vimrc} for initializations. |
| 365 All the other initializations are skipped. | |
| 366 Use this to edit a special kind of files. | |
| 367 It can also be used to skip all initializations by giving the name "NONE". | |
| 368 See ":help initialization" within vim for more details. | |
| 369 .TP | |
| 216 | 370 \-U {gvimrc} |
| 7 | 371 Use the commands in the file {gvimrc} for GUI initializations. |
| 372 All the other GUI initializations are skipped. | |
| 373 It can also be used to skip all GUI initializations by giving the name "NONE". | |
| 810 | 374 See ":help gui\-init" within vim for more details. |
| 7 | 375 .TP |
| 216 | 376 \-V[N] |
| 7 | 377 Verbose. Give messages about which files are sourced and for reading and |
| 378 writing a viminfo file. The optional number N is the value for 'verbose'. | |
| 379 Default is 10. | |
| 380 .TP | |
| 216 | 381 \-v |
| 7 | 382 Start |
| 383 .B Vim | |
| 384 in Vi mode, just like the executable was called "vi". This only has effect | |
| 385 when the executable is called "ex". | |
| 386 .TP | |
| 216 | 387 \-w {scriptout} |
| 7 | 388 All the characters that you type are recorded in the file |
| 389 {scriptout}, until you exit | |
| 390 .B Vim. | |
| 216 | 391 This is useful if you want to create a script file to be used with "vim \-s" or |
| 7 | 392 ":source!". |
| 393 If the {scriptout} file exists, characters are appended. | |
| 394 .TP | |
| 216 | 395 \-W {scriptout} |
| 396 Like \-w, but an existing file is overwritten. | |
| 7 | 397 .TP |
| 216 | 398 \-x |
| 33 | 399 Use encryption when writing files. Will prompt for a crypt key. |
| 7 | 400 .TP |
| 216 | 401 \-X |
| 7 | 402 Don't connect to the X server. Shortens startup time in a terminal, but the |
| 403 window title and clipboard will not be used. | |
| 404 .TP | |
| 216 | 405 \-y |
| 7 | 406 Start |
| 407 .B Vim | |
| 408 in easy mode, just like the executable was called "evim" or "eview". | |
| 409 Makes | |
| 410 .B Vim | |
| 411 behave like a click-and-type editor. | |
| 412 .TP | |
| 216 | 413 \-Z |
| 7 | 414 Restricted mode. Works like the executable starts with "r". |
| 415 .TP | |
| 216 | 416 \-\- |
| 7 | 417 Denotes the end of the options. |
| 418 Arguments after this will be handled as a file name. | |
| 216 | 419 This can be used to edit a filename that starts with a '\-'. |
| 7 | 420 .TP |
| 216 | 421 \-\-echo\-wid |
| 33 | 422 GTK GUI only: Echo the Window ID on stdout. |
| 7 | 423 .TP |
| 216 | 424 \-\-help |
| 425 Give a help message and exit, just like "\-h". | |
| 7 | 426 .TP |
| 216 | 427 \-\-literal |
| 33 | 428 Take file name arguments literally, do not expand wildcards. This has no |
| 429 effect on Unix where the shell expands wildcards. | |
| 7 | 430 .TP |
| 216 | 431 \-\-noplugin |
| 432 Skip loading plugins. Implied by \-u NONE. | |
| 7 | 433 .TP |
| 216 | 434 \-\-remote |
| 7 | 435 Connect to a Vim server and make it edit the files given in the rest of the |
| 436 arguments. If no server is found a warning is given and the files are edited | |
| 437 in the current Vim. | |
| 438 .TP | |
| 216 | 439 \-\-remote\-expr {expr} |
| 7 | 440 Connect to a Vim server, evaluate {expr} in it and print the result on stdout. |
| 441 .TP | |
| 216 | 442 \-\-remote\-send {keys} |
| 7 | 443 Connect to a Vim server and send {keys} to it. |
| 444 .TP | |
| 216 | 445 \-\-remote\-silent |
| 446 As \-\-remote, but without the warning when no server is found. | |
| 7 | 447 .TP |
| 216 | 448 \-\-remote\-wait |
| 449 As \-\-remote, but Vim does not exit until the files have been edited. | |
| 7 | 450 .TP |
| 216 | 451 \-\-remote\-wait\-silent |
| 452 As \-\-remote\-wait, but without the warning when no server is found. | |
| 7 | 453 .TP |
| 216 | 454 \-\-serverlist |
| 7 | 455 List the names of all Vim servers that can be found. |
| 456 .TP | |
| 216 | 457 \-\-servername {name} |
| 7 | 458 Use {name} as the server name. Used for the current Vim, unless used with a |
| 216 | 459 \-\-remote argument, then it's the name of the server to connect to. |
| 7 | 460 .TP |

| 534 Most of | |
| 535 .B Vim | |
| 536 was made by Bram Moolenaar, with a lot of help from others. | |

| 539 .br | |
| 540 .B Vim | |
| 541 is based on Stevie, worked on by: Tim Thompson, | |
| 542 Tony Andrews and G.R. (Fred) Walter. | |
| 543 Although hardly any of the original code remains. | |

| 548 Note that a number of things that may be regarded as bugs by some, are in fact | |
| 549 caused by a too-faithful reproduction of Vi's behaviour. | |
| 550 And if you think other things are bugs "because Vi does it differently", | |
| 551 you should take a closer look at the vi_diff.txt file (or type :help | |
| 552 vi_diff.txt when in Vim). | |
| 553 Also have a look at the 'compatible' and 'cpoptions' options. |
