COLUMN(1)                    UNIX Reference Manual                   COLUMN(1)

NAME
     column - columnate lists

SYNOPSIS
     column [-tx] [-c columns] [-s sep] [file ...]

DESCRIPTION
     The column utility formats its input into multiple columns.  Rows are
     filled before columns.  Input is taken from file operands, or, by de-
     fault, 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.

     Column exits 0 on success, >0 if an error occurred.

ENVIRONMENT
     COLUMNS  The environment variable COLUMNS is used to determine the size
              of the screen if no other information is available.

EXAMPLES
           (printf "PERM LINKS OWNER SIZE MONTH DAY HH:MM/YEAR NAME\n" ; \
           ls -l | sed 1d) | column -t
