.SH DESCRIPTION
|
|
The
|
|
.BR cut
|
|
utility selects portions of each line (as specified by
|
|
.BR list )
|
|
from each
|
|
.IR file
|
|
(or the standard input by default), and writes them to the
|
|
standard output.
|
|
The items specified by
|
|
.BR list
|
|
can be in terms of column position or in terms of fields delimited
|
|
by a special character. Column numbering starts from 1.
|
|
.LP
|
|
.BR List
|
|
is a comma or whitespace separated set of increasing numbers and/or
|
|
number ranges.
|
|
Number ranges consist of a number, a dash
|
|
.BR - ,
|
|
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
|
|
.BR Cut
|
|
exits 0 on success, 1 if an error occurred.
|
|
.SS OPTIONS
