column — columnate lists
column [−tx] [ −c columns ] [ −s sep ] [ file... ]
The column
utility formats its input into multiple columns. Rows are
filled before columns. Input is taken from file operands, or, by default,
from the standard input. Empty lines are ignored.
The options are as follows:
−cOutput is formatted for a display columns wide.
−sSpecify a set of characters to be used to delimit
columns for the −t
option.
−tDetermine 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 −s option. Useful
for pretty-printing displays.
−xFill columns before filling rows.
Column exits 0 on success, >0 if an error occurred.
COLUMNSThe environment variable COLUMNS is used to determine the size
of the screen if no other information is available.
