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

HISTORY

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