+.Sh SYNOPSIS
+.Nm cut
+.Fl c Ar list
+.Ar
+.Nm cut
+.Fl f Ar list
+.Op Fl d Ar string
+.Op Fl s
+.Ar
+.Sh DESCRIPTION
+The
+.Nm cut
+utility selects portions of each line (as specified by
+.Ar list )
+from each
+.Ar file
+(or the standard input by default), and writes them to the
+standard output.
+The items specified by
+.Ar list
+can be in terms of column position or in terms of fields delimited
+by a special character. Column numbering starts from 1.
+.Pp
+.Ar List
+is a comma or whitespace separated set of increasing numbers and/or
+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:
+.Bl -tag -width Fl
+.It Fl c Ar list
+The
+.Ar list
+specifies character positions.
+.It Fl d Ar string
+Use the first character of
+.Ar string
+as the field delimiter character instead of the tab character.
+.It Fl f Ar list
+The
+.Ar list
+specifies fields, delimited in the input by a single tab character.
+Output fields are separated by a single tab character.
+.It Fl s
+Suppresses lines with no field delimiter characters.
+Unless specified, lines with no delimiters are passed through unmodified.
+.El
+.Pp
+.Nm Cut
+exits 0 on success, 1 if an error occurred.
+.Sh SEE ALSO
+.Xr paste 1
+.Sh STANDARDS
+The
+.Nm cut
+utility is expected to conform to
+.St -p1003.2 .
