.SH DESCRIPTION
|
|
.B cut
|
|
out bytes, characters, or delimited fields from each line of the given
|
|
files and write to stdout. With no file, or when file is `-', cut reads
|
|
from stdin.
|
|
.P
|
|
.I list
|
|
is a comma or space separated list of numbers and ranges where numbering
|
|
starts from 1. Ranges are on the form `N-M'. If N or M is missing, the
|
|
beginning or end of line is assumed. Numbers and ranges may be repeated,
|
|
overlapping, and in any order. Selected input is written in the same
|
|
order that it is read, and is written exactly once.
