NAME
       column - columnate lists

SYNOPSIS
       column [options] file...

DESCRIPTION
       The  column  utility  formats  its  input into multiple columns.  Rows are filled before columns.  Input is taken from file or, by
       default, from standard input.  Empty lines are ignored.

OPTIONS
       -c, --columns width
              Output is formatted to a width specified as number of characters.

       -t, --table
              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 separator. Table output is useful for pretty-printing.

       -s, --separator separator
              Specify table separator (default is whitespace).

       -x, --fillrows
              Fill columns before filling rows.

       -h, --help
              Print help and exit.

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

EXAMPLES
       sed 's/#.*//' /etc/fstab | column -t

SEE ALSO
       colrm(1), ls(1), paste(1), sort(1)
