column [-ntx] [-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

-s Specify a set of characters to be used to delimit columns for the
-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

execution of column as described in environ(7).
The column utility exits 0 on success, and >0 if an error occurs.
