96 utility is a printing and pagination filter for text files.
97 When multiple input files are specified, each is read, formatted,
98 and written to standard output.
99 By default, the input is separated into 66-line pages, each with
102 A 5-line header with the page number, date, time, and
103 the pathname of the file.
105 A 5-line trailer consisting of blank lines.
108 If standard output is associated with a terminal,
109 diagnostic messages are suppressed until the
111 utility has completed processing.
113 When multiple column output is specified,
114 text columns are of equal width.
115 By default text columns are separated by at least one
117 Input lines that do not fit into a text column are truncated.
118 Lines are not truncated under single column output.
120 In the following option descriptions, column, lines, offset, page, and
121 width are positive decimal integers and gap is a nonnegative decimal integer.
124 Begin output at page number
126 of the formatted input.
128 Produce output that is
130 wide (default is 1) that is written vertically
131 down each column in the order in which the text
132 is received from the input file.
138 This option should not be used with

143 (To columnify and reshape text files more generally and without additional

150 option so that the columns are filled across the page in a round-robin order
151 (e.g., when column is 2, the first input line heads column
152 1, the second heads column 2, the third is the second line

242 depths (in lines), the
244 utility suppresses output of both the header and trailer, as if the
246 option were in effect.
248 Merge the contents of multiple files.
249 One line from each file specified by a file operand is
250 written side by side into text columns of equal fixed widths, in
251 terms of the number of column positions.
252 The number of text columns depends on the number of
253 file operands successfully opened.
254 The maximum number of files merged depends on page width and the
255 per process open file limit.
267 digit line numbering.
270 if not specified, is 5.
271 The number occupies the first
273 column positions of each text column or each line of
278 (any nondigit character) is given, it is appended to the line number to
279 separate it from whatever follows.
284 Line numbers longer than
286 columns are truncated.
288 Each line of output is preceded by
293 option is not specified, the default is zero.
294 The space taken is in addition to the output line width.
296 Pause before each page if the standard output is a terminal.
298 will write an alert character to standard error and wait for a carriage
299 return to be read on the terminal.
301 Write no diagnostic reports on failure to open a file.
303 Separate text columns by the single character
305 instead of by the appropriate number of
313 Print neither the five-line identifying
314 header nor the five-line trailer usually supplied for each page.
315 Quit printing after the last line of each file without spacing to the

320 column positions for multiple text-column output only.
323 option is not specified and the
325 option is not specified, the default width is 72.
328 option is not specified and the
330 option is specified, the default width is 512.

339 the standard input is used.
340 The standard input is used only if no
342 operands are specified, or if a
350 option does not allow the option letter to be separated from its
351 argument, and the options
356 require that both arguments, if present, not be separated from the option
363 receives an interrupt while printing to a terminal, it
364 flushes all accumulated error messages to the screen before
367 Error messages are written to standard error during the printing
368 process (if output is redirected) or after all successful
369 file printing is complete (when printing to a terminal).
388 utility does not recognize multibyte characters.
