+.Sh SYNOPSIS
+.Nm column
+.Op Fl tx
+.Op Fl c Ar columns
+.Op Fl s Ar sep
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm column
+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 Ds
+.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
+.Pp
+.Nm Column
+exits 0 on success, >0 if an error occurred.
+.Sh ENVIRONMENT
+.Bl -tag -width COLUMNS
+.It Ev COLUMNS
+The environment variable
+.Ev COLUMNS
+is used to determine the size of
+the screen if no other information is available.
+.El
+.Sh EXAMPLES
+.Dl (printf \&"PERM LINKS OWNER SIZE MONTH DAY HH:MM/YEAR NAME\en\&"\ \&;\ \&\e
+.Dl ls -l \&| sed 1d) \&| column -t
+.Sh SEE ALSO
