DESCRIPTION
The
utility selects portions of each line (as specified by
list
from each
file
(or the standard input by default), and writes them to the
standard output.
The items specified by
list
can be in terms of column position or in terms of fields delimited
by a special character. Column numbering starts from 1.
List
is a comma or whitespace separated set of increasing numbers and/or
number ranges.
Number ranges consist of a number, a dash
(-
)
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.
The options are as follows:
- -b list
-

list
specifies byte positions.
- -c list

list

- -d string
