DESCRIPTION
Paginate or columnate FILE(s) for printing.
Mandatory arguments to long options are mandatory for short options too.
+FIRST_PAGE[:LAST_PAGE], --pages=FIRST_PAGE[:LAST_PAGE]
begin [stop] printing with page FIRST_[LAST_]PAGE
-COLUMN, --columns=COLUMN
output COLUMN columns and print columns down, unless -a is used. Balance number of lines in the columns on each page.
-a, --across
print columns across rather than down, used together with -COLUMN
-c, --show-control-chars
use hat notation (^G) and octal backslash notation
-d, --double-space
double space the output
-D, --date-format=FORMAT
use FORMAT for the header date
-e[CHAR[WIDTH]], --expand-tabs[=CHAR[WIDTH]]
expand input CHARs (TABs) to tab WIDTH (8)
-F, -f, --form-feed
use form feeds instead of newlines to separate pages (by a 3-line page header with -F or a 5-line header and trailer without -F)
-h HEADER, --header=HEADER
use a centered HEADER instead of filename in page header, -h "" prints a blank line, don't use -h""
-i[CHAR[WIDTH]], --output-tabs[=CHAR[WIDTH]]
replace spaces with CHARs (TABs) to tab WIDTH (8)
-J, --join-lines
merge full lines, turns off -W line truncation, no column alignment, --sep-string[=STRING] sets separators
-l PAGE_LENGTH, --length=PAGE_LENGTH
set the page length to PAGE_LENGTH (66) lines (default number of lines of text 56, and with -F 63)
-m, --merge
print all files in parallel, one in each column, truncate lines, but join lines of full length with -J
-n[SEP[DIGITS]], --number-lines[=SEP[DIGITS]]
number lines, use DIGITS (5) digits, then SEP (TAB), default counting starts with 1st line of input file
-N NUMBER, --first-line-number=NUMBER
start counting with NUMBER at 1st line of first page printed (see +FIRST_PAGE)
-o MARGIN, --indent=MARGIN
offset each line with MARGIN (zero) spaces, do not affect -w or -W, MARGIN will be added to PAGE_WIDTH
-r, --no-file-warnings
omit warning when a file cannot be opened
-s[CHAR],--separator[=CHAR]
separate columns by a single character, default for CHAR is the <TAB> character without -w and 'no char' with -w -s[CHAR] turns off
line truncation of all 3 column options (-COLUMN|-a -COLUMN|-m) except -w is set
-SSTRING, --sep-string[=STRING]
separate columns by STRING, without -S: Default separator <TAB> with -J and <space> otherwise (same as -S" "), no effect on column
options
-t, --omit-header omit page headers and trailers
-T, --omit-pagination
omit page headers and trailers, eliminate any pagination by form feeds set in input files
-v, --show-nonprinting
use octal backslash notation
-w PAGE_WIDTH, --width=PAGE_WIDTH
set page width to PAGE_WIDTH (72) characters for multiple text-column output only, -s[char] turns off (72)
-W PAGE_WIDTH, --page-width=PAGE_WIDTH
set page width to PAGE_WIDTH (72) characters always, truncate lines, except -J option is set, no interference with -S or -s
--help display this help and exit
