+from each
+.Ar file
+(or the standard input by default), and writes them to the

+can be in terms of column position or in terms of fields delimited
+by a special character. Column numbering starts from 1.

+number ranges.
+Number ranges consist of a number, a dash
+.Pq Li \- ,
+and a second number
+and select the fields or columns from the first number to the second,
+inclusive.
+Numbers or number ranges may be preceded by a dash, which selects all
+fields or columns from 1 to the first number.
+Numbers or number ranges may be followed by a dash, which selects all
+fields or columns from the last number to the end of the line.
+Numbers and number ranges may be repeated, overlapping, and in any order.
+It is not an error to select fields or columns not present in the
+input line.
+.Pp
+The options are as follows:
