|
|
.FL "\-c" "Select out specific characters."
|
|
.FL "\-d" "Change the column delimiter to \fIdelim\fR."

.SH EXAMPLES

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