man column (Commandes) - column
NAME
column - columnate lists
SYNOPSIS
[-ntx] [-c columns] [-s sep] []
DESCRIPTION
The 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:
- -c
- Output is formatted for a display columns wide.
- -n
- By default, the command will merge multiple adjacent delimiters into a single delimiter when using the -t option; this option disables that behavior.
- -s
- Specify a set of characters to be used to delimit columns for the -t option.
- -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 -s option. Useful for pretty-printing displays.
- -x
- Fill columns before filling rows.
