+.Sh NAME
+.Nm column
+.Nd columnate lists
+.Sh SYNOPSIS
+.Nm
+.Op Fl tx
+.Op Fl c Ar columns
+.Op Fl s Ar sep
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility formats its input into multiple columns.
+Rows are filled before columns.
+Input is taken from
+.Ar file
+operands, or, by default, from the standard input.
+Empty lines are ignored.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl c
+Output is formatted for a display
+.Ar columns
+wide.
+.It Fl s
+Specify a set of characters to be used to delimit columns for the
+.Fl t
+option.
+.It Fl 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
+.Fl s
+option.
+Useful for pretty-printing displays.
+.It Fl x
+Fill columns before filling rows.
+.El
+.Sh ENVIRONMENT
+The
+.Ev COLUMNS , LANG , LC_ALL
+and
+.Ev LC_CTYPE
+environment variables affect the execution of
+.Nm
+as described in
+.Xr environ 7 .
+.Sh EXIT STATUS
+.Ex -std
+.Sh EXAMPLES
+.Dl (printf \&"PERM LINKS OWNER GROUP SIZE MONTH DAY \&"\ \&;\ \&\e
+.Dl printf \&"HH:MM/YEAR NAME\en\&"\ \&;\ \&\e
+.Dl ls -l \&| sed 1d) \&| column -t
+.Sh SEE ALSO
+.Xr colrm 1 ,
+.Xr ls 1 ,
+.Xr paste 1 ,
+.Xr sort 1
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.3 Reno .
+.Sh BUGS
+Input lines are limited to
+.Dv LINE_MAX
+(2048) bytes in length.
