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:
-c
- Output is formatted for a display columns wide.
-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.
COLUMNS
- The environment variable
COLUMNS
is used to
determine the size of the screen if no other information is
available.
The column
utility exits 0 on success,
and >0 if an error occurs.
