utility formats its input into multiple
columns. Each input line provides the text for one output cell. Columns are
filled before rows.
The column width is determined by the longest input line rounded up to the
nearest tabstop; tabstops are assumed to be at multiples of eight. Output uses
tab characters to advance to the next column. The number of columns is chosen
to fill the terminal width.
Input is taken from file
operands or, by
default, from the standard input. Empty lines and lines containing only
whitespace are ignored.
The options are as follows:
- Output is formatted for a display
- Specify a set of characters to delimit columns for the
-t option. It defaults to space and tab.
- Table mode. Each input line provides the text for one
output row. It is split into cells using the
-s option. Leading, trailing, and multiple
adjacent delimiters are ignored. Each column is as wide as the widest cell
in it. Columns are separated by two spaces.
- Fill rows before filling columns.
- If set to a positive integer, output is formatted to the
given width in display columns. Otherwise,
column defaults to the terminal width, or 80
columns if the output is not a terminal.
- The character encoding
locale(1). It decides which
byte sequences form characters, what their display width is, and which
characters are whitespace. If unset or set to “C”,
“POSIX”, or an unsupported value, each byte except the tab is
treated as a character of display width 1.
utility exits 0 on success,
and >0 if an error occurs.
