24 | .SH NAME | |
25 | less \- opposite of more | |
26 | .SH SYNOPSIS | |
27 | .B "less [-[+]aABcCdeEimMnqQuUsw] [-b\fIN\fB] [-h\fIN\fB] [-x\fIN\fB] [-[z]\fIN\fB]" | |
28 | .br | |
29 | .B " [-P[mM=]\fIstring\fB] [-[lL]\fIlogfile\fB] [+\fIcmd\fB]" | |
30 | .br | |
31 | .B " [-t\fItag\fB] [\fIfilename\fB]..." | |
32 | .SH DESCRIPTION | |
33 | .I Less | |
34 | is a program similar to | |
35 | .I more | |
36 | (1), but which allows backwards movement | |
37 | in the file as well as forward movement. | |
38 | Also, | |
39 | .I less | |
40 | does not have to read the entire input file before starting, | |
41 | so with large input files it starts up faster than text editors like | |
42 | .I vi | |
43 | (1). | |
44 | .I Less | |
45 | uses termcap (or terminfo on some systems), | |
46 | so it can run on a variety of terminals. | |
47 | There is even limited support for hardcopy terminals. | |
48 | (On a hardcopy terminal, lines which should be printed at the top | |
49 | of the screen are prefixed with an up-arrow.) | |
50 | .PP | |
51 | Commands are based on both | |
52 | .I more | |
53 | and | |
54 | .I vi. | |
55 | Commands may be preceeded by a decimal number, | |
56 | called N in the descriptions below. | |
57 | The number is used by some commands, as indicated. | |
58 | ||
59 | .SH COMMANDS | |
60 | In the following descriptions, ^X means control-X. | |
61 | ESC stands for the ESCAPE key; for example ESC-v means the | |
62 | two character sequence "ESCAPE", then "v". | |
63 | .IP H | |
64 | Help: display a summary of these commands. | |
65 | If you forget all the other commands, remember this one. | |
66 | .PP | |
67 | .IP "SPACE or f or ^F or ^V" | |
68 | Scroll forward N lines, default one window (see option -z below). | |
69 | If N is more than the screen size, only the final screenful is displayed. | |
70 | Warning: some systems use ^V as a special literalization character. | |
71 | .PP | |
72 | .IP "b or ^B or ESC-v" | |
73 | Scroll backward N lines, default one window (see option -z below). | |
74 | If N is more than the screen size, only the final screenful is displayed. | |
75 | .PP | |
76 | .IP "RETURN or ^N or e or ^E or j or ^J" | |
77 | Scroll forward N lines, default 1. | |
78 | The entire N lines are displayed, even if N is more than the screen size. | |
79 | .PP | |
80 | .IP "y or ^Y or ^P or k or ^K" | |
81 | Scroll backward N lines, default 1. | |
82 | The entire N lines are displayed, even if N is more than the screen size. | |
83 | Warning: some systems use ^Y as a special job control character. | |
84 | .PP | |
85 | .IP "d or ^D" | |
86 | Scroll forward N lines, default one half of the screen size. | |
87 | If N is specified, it becomes the new default for | |
88 | subsequent d and u commands. | |
89 | .PP | |
90 | .IP "u or ^U" | |
91 | Scroll backward N lines, default one half of the screen size. | |
92 | If N is specified, it becomes the new default for | |
93 | subsequent d and u commands. | |
94 | .PP | |
95 | .IP "r or ^R or ^L" | |
96 | Repaint the screen. | |
97 | .PP | |
98 | .IP R | |
99 | Repaint the screen, discarding any buffered input. | |
100 | Useful if the file is changing while it is being viewed. | |
101 | .PP | |
102 | .IP "g or < or ESC-<" | |
103 | Go to line N in the file, default 1 (beginning of file). | |
104 | (Warning: this may be slow if N is large.) | |
105 | .PP | |
106 | .IP "G or > or ESC->" | |
107 | Go to line N in the file, default the end of the file. | |
108 | (Warning: this may be slow if N is large, | |
109 | or if N is not specified and | |
110 | standard input, rather than a file, is being read.) | |
111 | .PP | |
112 | .IP "p or %" | |
113 | Go to a position N percent into the file. | |
114 | N should be between 0 and 100. | |
115 | (This works if standard input is being read, but only if | |
116 | .I less | |
117 | has already read to the end of the file. | |
118 | It is always fast, but not always useful.) | |
119 | .PP | |
120 | .IP m | |
121 | Followed by any lowercase letter, | |
122 | marks the current position with that letter. | |
123 | .PP | |
124 | .IP "'" | |
125 | (Single quote.) | |
126 | Followed by any lowercase letter, returns to the position which | |
127 | was previously marked with that letter. | |
128 | Followed by another single quote, returns to the postion at | |
129 | which the last "large" movement command was executed. | |
130 | All marks are lost when a new file is examined. | |
131 | .PP | |
132 | .IP "^X^X" | |
133 | Same as single quote. | |
134 | .PP | |
135 | .IP /pattern | |
136 | Search forward in the file for the N-th line containing the pattern. | |
137 | N defaults to 1. | |
138 | The pattern is a regular expression, as recognized by | |
139 | .I ed. | |
140 | The search starts at the second line displayed | |
141 | (but see the -a option, which changes this). | |
142 | .PP | |
143 | .IP ?pattern | |
144 | Search backward in the file for the N-th line containing the pattern. | |
145 | The search starts at the line immediately before the top line displayed. | |
146 | .PP | |
147 | .IP /!pattern | |
148 | Like /, but the search is for the N-th line | |
149 | which does NOT contain the pattern. | |
150 | .PP | |
151 | .IP ?!pattern | |
152 | Like ?, but the search is for the N-th line | |
153 | which does NOT contain the pattern. | |
154 | .PP | |
155 | .IP n | |
156 | Repeat previous search, for N-th line containing the last pattern | |
157 | (or NOT containing the last pattern, if the previous search | |
158 | was /! or ?!). | |
159 | .PP | |
160 | .IP "E [filename]" | |
161 | Examine a new file. | |
162 | If the filename is missing, the "current" file (see the N and P commands | |
163 | below) from the list of files in the command line is re-examined. | |
164 | If the filename is a pound sign (#), the previously examined file is | |
165 | re-examined. | |
166 | .PP | |
167 | .IP "^X^V or :e" | |
168 | Same as E. | |
169 | Warning: some systems use ^V as a special literalization character. | |
170 | .PP | |
171 | .IP "N or :n" | |
172 | Examine the next file (from the list of files given in the command line). | |
173 | If a number N is specified (not to be confused with the command N), | |
174 | the N-th next file is examined. | |
175 | .PP | |
176 | .IP "P or :p" | |
177 | Examine the previous file. | |
178 | If a number N is specified, the N-th previous file is examined. | |
179 | .PP | |
180 | .IP "= or ^G" | |
181 | Prints some information about the file being viewed, | |
182 | including its name | |
183 | and the line number and byte offset of the bottom line being displayed. | |
184 | If possible, it also prints the length of the file | |
185 | and the percent of the file above the last displayed line. | |
186 | .PP | |
187 | .IP \- | |
188 | Followed by one of the command line option letters (see below), | |
189 | this will change the setting of that option | |
190 | and print a message describing the new setting. | |
191 | If the option letter has a numeric value (such as -b or -h), | |
192 | or a string value (such as -P or -t), | |
193 | a new value may be entered after the option letter. | |
194 | .PP | |
195 | .IP \_ | |
196 | (Underscore.) | |
197 | Followed by one of the command line option letters (see below), | |
198 | this will print a message describing the current setting of that option. | |
199 | The setting of the option is not changed. | |
200 | .PP | |
201 | .IP +cmd | |
202 | Causes the specified cmd to be executed each time a new file is examined. | |
203 | For example, +G causes | |
204 | .I less | |
205 | to initially display each file starting at the end | |
206 | rather than the beginning. | |
207 | .PP | |
208 | .IP V | |
209 | Prints the version number of | |
210 | .I less | |
211 | being run. | |
212 | .PP | |
213 | .IP "q or :q or ZZ" | |
214 | Exits | |
215 | .I less. | |
216 | .PP | |
217 | The following | |
218 | two | |
219 | commands may or may not be valid, depending on your particular installation. | |
220 | .PP | |
221 | .IP v | |
222 | Invokes an editor to edit the current file being viewed. | |
223 | The editor is taken from the environment variable EDITOR, | |
224 | or defaults to "vi". | |
225 | .PP | |
226 | .IP "! shell-command" | |
227 | Invokes a shell to run the shell-command given. | |
228 | A percent sign in the command is replaced by the name of the | |
229 | current file. "!!" repeats the last shell command. | |
230 | "!" with no shell command simply invokes a shell. | |
231 | In all cases, the shell is taken from the environment variable SHELL, | |
232 | or defaults to "sh". | |
233 | .PP | |
234 | .SH OPTIONS | |
235 | Command line options are described below. | |
236 | Most options may be changed while | |
237 | .I less | |
238 | is running, via the "\-" command. | |
239 | .PP | |
240 | Options are also taken from the environment variable "LESS". | |
241 | For example, | |
242 | to avoid typing "less -options ..." each time | |
243 | .I less | |
244 | is invoked, you might tell | |
245 | .I csh: | |
246 | .sp | |
247 | setenv LESS "-options" | |
248 | .sp | |
249 | or if you use | |
250 | .I sh: | |
251 | .sp | |
252 | LESS="-options"; export LESS | |
253 | .sp | |
254 | The environment variable is parsed before the command line, | |
255 | so command line options override the LESS environment variable. | |
256 | If an option appears in the LESS variable, it can be reset | |
257 | to its default on the command line by beginning the command | |
258 | line option with "-+". | |
259 | .sp | |
260 | A dollar sign ($) may be used to signal the end of an option string. | |
261 | This is important only for options like -P which take a | |
262 | following string. | |
263 | .IP -a | |
264 | Normally, forward searches start just after | |
265 | the top displayed line (that is, at the second displayed line). | |
266 | Thus, forward searches include the currently displayed screen. | |
267 | The -a option causes forward searches to start | |
268 | just after the bottom line displayed, | |
269 | thus skipping the currently displayed screen. | |
270 | .IP -A | |
271 | The -A option causes searches to start at the second SCREEN line | |
272 | displayed, as opposed to the default which is to start at the second | |
273 | REAL line displayed. | |
274 | For example, suppose a long real line occupies the first three screen lines. | |
275 | The default search will start at the second real line (the fourth | |
276 | screen line), while the -A option | |
277 | will cause the search to start at the second screen line (in the | |
278 | midst of the first real line). | |
279 | (This option is rarely useful.) | |
280 | .IP -b | |
281 | The -b\fIn\fR option tells | |
282 | .I less | |
283 | to use a non-standard number of buffers. | |
284 | Buffers are 1K, and normally 10 buffers are used | |
285 | (except if data in coming from standard input; see the -B option). | |
286 | The number \fIn\fR specifies a different number of buffers to use. | |
287 | .IP -B | |
288 | Normally, when data is coming from standard input, | |
289 | buffers are allocated automatically as needed, to avoid loss of data. | |
290 | The -B option disables this feature, so that only the default number | |
291 | of buffers are used. | |
292 | If more data is read than will fit in the buffers, the oldest | |
293 | data is discarded. | |
294 | .IP -c | |
295 | Normally, | |
296 | .I less | |
297 | will repaint the screen by scrolling from the bottom of the screen. | |
298 | If the -c option is set, when | |
299 | .I less | |
300 | needs to change the entire display, it will paint from the top line down. | |
301 | .IP -C | |
302 | The -C option is like -c, but the screen is cleared before it is repainted. | |
303 | .IP -d | |
304 | Normally, | |
305 | .I less | |
306 | will complain if the terminal is dumb; that is, lacks some important capability, | |
307 | such as the ability to clear the screen or scroll backwards. | |
308 | The -d option suppresses this complaint | |
309 | (but does not otherwise change the behavior of the program on a dumb terminal). | |
310 | .IP -e | |
311 | Normally the only way to exit less is via the "q" command. | |
312 | The -e option tells less to automatically exit | |
313 | the second time it reaches end-of-file. | |
314 | .IP -E | |
315 | The -E flag causes less to exit the first time it reaches end-of-file. | |
316 | .IP -h | |
317 | Normally, | |
318 | .I less | |
319 | will scroll backwards when backwards movement is necessary. | |
320 | The -h option specifies a maximum number of lines to scroll backwards. | |
321 | If it is necessary to move backwards more than this many lines, | |
322 | the screen is repainted in a forward direction. | |
323 | (If the terminal does not have the ability to scroll | |
324 | backwards, -h0 is implied.) | |
325 | .IP -i | |
326 | The -i option causes searches to ignore case; that is, | |
327 | uppercase and lowercase are considered identical. | |
328 | Also, text which is overstruck or underlined can be searched for. | |
329 | .IP -l | |
330 | The -l option, followed immediately by a filename, | |
331 | will cause | |
332 | .I less | |
333 | to copy its input to the named file as it is being viewed. | |
334 | This applies only when the input file is a pipe, | |
335 | not an ordinary file. | |
336 | If the file already exists, less will ask for confirmation before | |
337 | overwriting it. | |
338 | .IP -L | |
339 | The -L option is like -l, but it will overwrite an existing | |
340 | file without asking for confirmation. | |
341 | .sp | |
342 | If no log file has been specified, | |
343 | the -l and -L options can be used from within less to specify a log file. | |
344 | Without a file name, they will simply report the name of the log file. | |
345 | .IP -m | |
346 | Normally, | |
347 | .I less | |
348 | prompts with a colon. | |
349 | The -m option causes | |
350 | .I less | |
351 | to prompt verbosely (like | |
352 | .I more), | |
353 | with the percent into the file. | |
354 | .IP -M | |
355 | The -M option causes | |
356 | .I less | |
357 | to prompt even more verbosely than | |
358 | .I more. | |
359 | .IP -n | |
360 | The -n flag suppresses line numbers. | |
361 | The default (to use line numbers) may cause | |
362 | .I less | |
363 | to run more slowly in some cases, especially with a very large input file. | |
364 | Suppressing line numbers with the -n flag will avoid this problem. | |
365 | Using line numbers means: the line number will be displayed in the verbose | |
366 | prompt and in the = command, | |
367 | and the v command will pass the current line number to the editor. | |
368 | .IP -P | |
369 | The -P option provides a way to tailor the three prompt | |
370 | styles to your own preference. | |
371 | You would normally put this option in your LESS environment | |
372 | variable, rather than type it in with each less command. | |
373 | Such an option must either be the last option in the LESS variable, | |
374 | or be terminated by a dollar sign. | |
375 | -P followed by a string changes the default (short) prompt to that string. | |
376 | -Pm changes the medium (-m) prompt to the string, and | |
377 | -PM changes the long (-M) prompt. | |
378 | Also, -P= changes the message printed by the = command to the given string. | |
379 | All prompt strings consist of a sequence of | |
380 | letters and special escape sequences. | |
381 | See the section on PROMPTS for more details. | |
382 | .IP -q | |
383 | Normally, if an attempt is made to scroll past the end of the file | |
384 | or before the beginning of the file, the terminal bell is rung to | |
385 | indicate this fact. | |
386 | The -q option tells | |
387 | .I less | |
388 | not to ring the bell at such times. | |
389 | If the terminal has a "visual bell", it is used instead. | |
390 | .IP -Q | |
391 | Even if -q is given, | |
392 | .I less | |
393 | will ring the bell on certain other errors, | |
394 | such as typing an invalid character. | |
395 | The -Q option tells | |
396 | .I less | |
397 | to be quiet all the time; that is, never ring the terminal bell. | |
398 | If the terminal has a "visual bell", it is used instead. | |
399 | .IP -s | |
400 | The -s option causes | |
401 | consecutive blank lines to be squeezed into a single blank line. | |
402 | This is useful when viewing | |
403 | .I nroff | |
404 | output. | |
405 | .IP -t | |
406 | The -t option, followed immediately by a TAG, | |
407 | will edit the file containing that tag. | |
408 | For this to work, there must be a file called "tags" in the | |
409 | current directory, which was previously built by the | |
410 | .I ctags | |
411 | (1) command. | |
412 | This option may also be specified from within less | |
413 | (using the \- command) as a way of examining a new file. | |
414 | .IP -u | |
415 | If the -u option is given, | |
416 | backspaces are treated as printable characters; | |
417 | that is, they are sent to the terminal when they appear in the input. | |
418 | .IP -U | |
419 | If the -U option is given, | |
420 | backspaces are printed as the two character sequence "^H". | |
421 | .sp | |
422 | If neither -u nor -U is given, | |
423 | backspaces which appear adjacent to an underscore character | |
424 | are treated specially: | |
425 | the underlined text is displayed | |
426 | using the terminal's hardware underlining capability. | |
427 | Also, backspaces which appear between two identical characters | |
428 | are treated specially: | |
429 | the overstruck text is printed | |
430 | using the terminal's hardware boldface capability. | |
431 | Other backspaces are deleted, along with the preceeding character. | |
432 | .IP -w | |
433 | Normally, | |
434 | .I less | |
435 | uses a tilde character to represent lines past the end of the file. | |
436 | The -w option causes blank lines to be used instead. | |
437 | .IP -x | |
438 | The -x\fIn\fR option sets tab stops every \fIn\fR positions. | |
439 | The default for \fIn\fR is 8. | |
440 | .IP -[z] | |
441 | When given a backwards or forwards window command, | |
442 | .I less | |
443 | will by | |
444 | default scroll backwards or forwards one screenful of lines. | |
445 | The -z\fIn\fR option changes the default scrolling window size | |
446 | to \fIn\fR lines. | |
447 | Note that the "z" is optional for compatibility with | |
448 | .I more. | |
449 | .IP + | |
450 | If a command line option begins with \fB+\fR, | |
451 | the remainder of that option is taken to be an initial command to | |
452 | .I less. | |
453 | For example, +G tells | |
454 | .I less | |
455 | to start at the end of the file rather than the beginning, | |
456 | and +/xyz tells it to start at the first occurence of "xyz" in the file. | |
457 | As a special case, +<number> acts like +<number>g; | |
458 | that is, it starts the display at the specified line number | |
459 | (however, see the caveat under the "g" command above). | |
460 | If the option starts with \fB++\fR, the initial command applies to | |
461 | every file being viewed, not just the first one. | |
462 | The + command described previously | |
463 | may also be used to set (or change) an initial command for every file. | |
464 | ||
465 | .SH "KEY BINDINGS" | |
466 | You may define your own less commands by using the program | |
467 | .I lesskey | |
468 | (1) | |
469 | to create a file called ".less" in your home directory. | |
470 | This file specifies a set of command keys and an action | |
471 | associated with each key. | |
472 | See the | |
473 | .I lesskey | |
474 | manual page for more details. | |
475 | ||
476 | .SH "PROMPTS" | |
477 | The -P option allows you to tailor the prompt to your preference. | |
478 | The string given to the -P option replaces the specified prompt string. | |
479 | Certain characters in the string are interpreted specially. | |
480 | The prompt mechanism is rather complicated to provide flexibility, | |
481 | but the ordinary user need not understand the details of constructing | |
482 | personalized prompt strings. | |
483 | .sp | |
484 | A percent sign followed by a single character is expanded | |
485 | according to what the following character is: | |
486 | .IP "%bX" | |
487 | Replaced by the byte offset into the current input file. | |
488 | The b is followed by a single character (shown as X above) | |
489 | which specifies the line whose byte offset is to be used. | |
490 | If the character is a "t", the byte offset of the top line in the | |
491 | display is used, | |
492 | an "m" means use the middle line, | |
493 | a "b" means use the bottom line, | |
494 | and a "B" means use the line just after the bottom line. | |
495 | .IP "%f" | |
496 | Replaced by the name of the current input file. | |
497 | .IP "%i" | |
498 | Replaced by the index of the current file in the list of | |
499 | input files. | |
500 | .IP "%lX" | |
501 | Replaced by the line number of a line in the input file. | |
502 | The line to be used is determined by the X, as with the %b option. | |
503 | .IP "%m" | |
504 | Replaced by the total number of input files. | |
505 | .IP "%pX" | |
506 | Replaced by the percent into the current input file. | |
507 | The line used is determined by the X as with the %b option. | |
508 | .IP "%s" | |
509 | Replaced by the size of the current input file. | |
510 | .IP "%t" | |
511 | Causes any trailing spaces to be removed. | |
512 | Usually used at the end of the string, but may appear anywhere. | |
513 | .IP "%x" | |
514 | Replaced by the name of the next input file in the list. | |
515 | .PP | |
516 | If any item is unknown (for example, the file size if input | |
517 | is a pipe), a question mark is printed instead. | |
518 | .PP | |
519 | The format of the prompt string can be changed | |
520 | depending on certain conditions. | |
521 | A question mark followed by a single character acts like an "IF": | |
522 | depending on the following character, a condition is evaluated. | |
523 | If the condition is true, any characters following the question mark | |
524 | and condition character, up to a period, are included in the prompt. | |
525 | If the condition is false, such characters are not included. | |
526 | A colon appearing between the question mark and the | |
527 | period can be used to establish an "ELSE": any characters between | |
528 | the colon and the period are included in the string if and only if | |
529 | the IF condition is false. | |
530 | Condition characters (which follow a question mark) may be: | |
531 | .IP "?a" | |
532 | True if any characters have been included in the prompt so far. | |
533 | .IP "?bX" | |
534 | True if the byte offset of the specified line is known. | |
535 | .IP "?e" | |
536 | True if at end-of-file. | |
537 | .IP "?f" | |
538 | True if there is an input filename | |
539 | (that is, if input is not a pipe). | |
540 | .IP "?lX" | |
541 | True if the line number of the specified line is known. | |
542 | .IP "?m" | |
543 | True if there is more than one input file. | |
544 | .IP "?n" | |
545 | True if this is the first prompt in a new input file. | |
546 | .IP "?pX" | |
547 | True if the percent into the current input file | |
548 | of the specified line is known. | |
549 | .IP "?s" | |
550 | True if the size of current input file is known. | |
551 | .IP "?x" | |
552 | True if there is a next input file | |
553 | (that is, if the current input file is not the last one). | |
554 | .PP | |
555 | Any characters other than the special ones | |
556 | (question mark, colon, period, percent, and backslash) | |
557 | become literally part of the prompt. | |
558 | Any of the special characters may be included in the prompt literally | |
559 | by preceeding it with a backslash. | |
560 | .PP | |
561 | Some examples: | |
562 | .sp | |
563 | ?f%f:Standard input. | |
564 | .sp | |
565 | This prompt prints the filename, if known; | |
566 | otherwise the string "Standard input". | |
567 | .sp | |
568 | ?f%f .?ltLine %lt:?pt%pt\%:?btByte %bt:-... | |
569 | .sp | |
570 | This prompt would print the filename, if known. | |
571 | The filename is followed by the line number, if known, | |
572 | otherwise the percent if known, otherwise the byte offset if known. | |
573 | Otherwise, a dash is printed. | |
574 | Notice how each question mark has a matching period, | |
575 | and how the % after the %pt | |
576 | is included literally by escaping it with a backslash. | |
577 | .sp | |
578 | ?n?f%f\ .?m(file\ %i\ of\ %m)\ ..?e(END)\ ?x-\ Next\\:\ %x..%t | |
579 | .sp | |
580 | This prints the filename if this is the first prompt in a file, | |
581 | followed by the "file N of N" message if there is more | |
582 | than one input file. | |
583 | Then, if we are at end-of-file, the string "(END)" is printed | |
584 | followed by the name of the next file, if there is one. | |
585 | Finally, any trailing spaces are truncated. | |
586 | This is the default prompt. | |
587 | For reference, here are the defaults for | |
588 | the other two prompts (-m and -M respectively). | |
589 | Each is broken into two lines here for readability only. | |
590 | .nf | |
591 | .sp | |
592 | ?n?f%f\ .?m(file\ %i\ of\ %m)\ ..?e(END)\ ?x-\ Next\\:\ %x.: | |
593 | ?pB%pB\\%:byte\ %bB?s/%s...%t | |
594 | .sp | |
595 | ?f%f\ .?n?m(file\ %i\ of\ %m)\ ..?ltline\ %lt\ :byte\ %bB?s/%s\ .. | |
596 | ?e(END)\ ?x-\ Next\\:\ %x.:?pB%pB\\%..%t | |
597 | .sp | |
598 | .fi | |
599 | And here is the default message produced by the = command: | |
600 | .nf | |
601 | .sp | |
602 | ?f%f\ .?m(file\ %i\ of\ %m)\ .?ltline\ %lt\ . | |
603 | byte\ %bB?s/%s.\ ?e(END)\ :?pB%pB\\%..%t | |
604 | .fi | |
