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 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, --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, --first-line-number=NUMBER start counting with NUMBER at 1st line of first page printed (see +FIRST_PAGE) -o, --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 -S[STRING], --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, --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 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 --version output version information and exit -t is implied if PAGE_LENGTH <= 10. With no FILE, or when FILE is -, read standard input. GNU coreutils online help: <http://www.gnu.org/software/coreutils/> Report pr translation bugs to <http://translationproject.org/team/> AUTHOR
