COLUMN(1)                                 User Commands                                 COLUMN(1)



NAME
       column - columnate lists

SYNOPSIS
       column [options] file...

DESCRIPTION
       The  column  utility formats its input into multiple columns.  Rows are filled before col-
       umns.  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 separators
              Specify possible table delimiters (default is whitespace).

       -o, --output-separator separators
              Specify table output delimiter (default is two whitespaces).

       -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

BUGS
       The util-linux version 2.23 changed -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

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

HISTORY
       The column command appeared in 4.3BSD-Reno.

AVAILABILITY
       The column command is part of the util-linux package and is available from  ftp://ftp.ker-
