NAME         top

       column - columnate lists

SYNOPSIS         top

       column [options] [file...]

DESCRIPTION         top

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

OPTIONS         top

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

       -o, --output-separator string
              Specify the columns delimiter for table output (default is two

       -s, --separator separators
              Specify the possible input item delimiters (default is

       -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 --output-separator
              option.  Table output is useful for pretty-printing.

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

       screen if no other information is available.

EXAMPLES         top

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

BUGS         top

       Version 2.23 changed the -s option to be non-greedy, for example:

       printf "a:b:c\n1::3\n" | column  -t -s ':'

       Old output:
       a  b  c
       1  3

       New output (since util-linux 2.23):
       a  b  c
       1     3
