| 30 | .SH DESCRIPTION
|
|---|
| 31 | .PP
|
|---|
| 32 | \fICut\fR extracts one or more fields or columns from a file and writes them on
|
|---|
| 33 | standard output.
|
|---|
| 34 | If the \fB\-f\fR flag is used, the fields are separated by a delimiter
|
|---|
| 35 | character, normally a tab, but can be changed using the \fB\-d\fR flag.
|
|---|
| 36 | If the \fB\-c\fR flag is used, specific columns can be specified.
|
|---|
| 37 | The list can be comma or BLANK separated. The \fB\-f\fR and
|
|---|
| 38 | \fB\-c\fR flags are mutually exclusive.
|
|---|
| 39 | Note: The POSIX1003.2 standard requires the option \-b to cut out
|
|---|
| 40 | specific bytes in a file. It is intended for systems with multi byte
|
|---|
| 41 | characters (e.g. kanji), since MINIX uses only one byte characters,
|
|---|
| 42 | this option is equivalent to \-c. For the same reason, the option
|
|---|
| 43 | \-n has no effect and is not listed in this manual page.
