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 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 charac- ters. -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.
