Rows are filled before columns. Input is taken from .Ar file operands, or, by default, from the standard input. Empty lines are ignored. .Pp The options are as follows: .Bl -tag -width indent .It Fl c Output is formatted for a display .Ar columns wide. +.It Fl l +When used with +.Fl t , +limit the table to +.Ar tblcols +columns in width. +The last column will contain the rest of the line, +including any delimiters. .It Fl s Specify a set of characters to be used to delimit columns for the .Fl t option. .It Fl t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the .Fl s option. Useful for pretty-printing displays. .It Fl x Fill columns before filling rows. .El .Sh ENVIRONMENT The .Ev COLUMNS , LANG , LC_ALL and .Ev LC_CTYPE environment variables affect the execution of .Nm as described in .Xr environ 7 . .Sh EXIT STATUS .Ex -std .Sh EXAMPLES .Dl (printf \&"PERM LINKS OWNER GROUP SIZE MONTH DAY \&"\ \&;\ \&\e .Dl printf \&"HH:MM/YEAR NAME\en\&"\ \&;\ \&\e .Dl ls -l \&| sed 1d) \&| column -t .Sh SEE ALSO .Xr colrm 1 , .Xr ls 1 , .Xr paste 1 , .Xr sort 1 .Sh HISTORY The .Nm command appeared in .Bx 4.3 Reno . .Sh BUGS Input lines are limited to .Dv LINE_MAX (2048) bytes in length. diff --git a/usr.bin/column/column.c b/usr.bin/column/column.c index a808113649bc..97fc83e6b589 100644 --- a/usr.bin/column/column.c +++ b/usr.bin/column/column.c @@ -1,339 +1,364 @@ /*- * SPDX-License-Identifier: BSD-3-Clause * * Copyright (c) 1989, 1993, 1994 * The Regents of the University of California.
