52 | .Sh DESCRIPTION | |
53 | The | |
54 | .Nm cut | |
55 | utility selects portions of each line (as specified by | |
56 | .Ar list ) | |
57 | from each | |
58 | .Ar file | |
59 | (or the standard input by default), and writes them to the | |
60 | standard output. | |
61 | The items specified by | |
62 | .Ar list | |
63 | can be in terms of column position or in terms of fields delimited | |
64 | by a special character. Column numbering starts from 1. | |
65 | .Pp | |
66 | .Ar List | |
67 | is a comma or whitespace separated set of increasing numbers and/or | |
68 | number ranges. | |
69 | Number ranges consist of a number, a dash | |
70 | .Pq Li \- , | |
71 | and a second number | |
72 | and select the fields or columns from the first number to the second, | |
73 | inclusive. | |
74 | Numbers or number ranges may be preceded by a dash, which selects all | |
75 | fields or columns from 1 to the first number. | |
76 | Numbers or number ranges may be followed by a dash, which selects all | |
77 | fields or columns from the last number to the end of the line. | |
78 | Numbers and number ranges may be repeated, overlapping, and in any order. | |
79 | It is not an error to select fields or columns not present in the | |
80 | input line. | |
81 | .Pp | |
82 | The options are as follows: | |
83 | .Bl -tag -width Fl | |
84 | .It Fl c Ar list | |
85 | The | |
86 | .Ar list | |
87 | specifies character positions. | |
88 | .It Fl d Ar string | |
89 | Use | |
90 | .Ar char | |
91 | as the field delimiter character instead of the tab character. | |
92 | .It Fl f Ar list | |
93 | The | |
94 | .Ar list | |
95 | specifies fields, delimited in the input by a single tab character. | |
96 | Output fields are separated by a single tab character. | |
97 | .It Fl s | |
98 | Suppresses lines with no field delimiter characters. | |
99 | Unless specified, lines with no delimiters are passed through unmodified. | |
