NAME

     column --- columnate lists

SYNOPSIS

     column [-entx] [-c columns] [-s sep] [file ...]

DESCRIPTION

     The column utility formats its input into multiple columns.  Rows are
     filled before columns.  Input is taken from file operands, or, by
     default, from the standard input.  Empty lines are ignored unless the -e
     option is used.

     The options are as follows:

     -c      Output is formatted for a display columns wide.

     -s      Specify a set of characters to be used to delimit columns for the
         -t option.

     -t      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 -s option.  Useful for
         pretty-printing displays.

     -x      Fill columns before filling rows.

     -n      By default, the column command will merge multiple adjacent
         delimiters into a single delimiter when using the -t option; this
         option disables that behavior. This option is a Debian GNU/Linux
         extension.

     -e      Do not ignore empty lines.

ENVIRONMENT

     The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the
     execution of column as described in environ(7).

EXIT STATUS

     The column utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

       (printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; \
       printf "HH:MM/YEAR NAME\n" ; \
       ls -l | sed 1d) | column -t

SEE ALSO

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

HISTORY

     The column command appeared in 4.3BSD-Reno.

BUGS

     Input lines are limited to 512 times LINE_MAX (1M) wide characters in
     length.

Free Software


Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
