.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBcut\fR utility selects portions of each line (as specified by \fIlist\fR)
from each \fIfile\fR (or the standard input by default), and writes them to
the standard output.  The items specified by \fIlist\fR can be in terms of
column position or in terms of fields delimited by a special
character. Column numbering starts from 1.
.PP
\&\fIlist\fR 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.
.SH "OPTIONS"
.IX Header "OPTIONS"
\&\fBcut\fR accepts the following options:
.IP "\-b list" 4
.IX Item "-b list"
The \fIlist\fR specifies byte positions.
.IP "\-c list" 4
.IX Item "-c list"
The \fIlist\fR specifies character positions.
.IP "\-d string" 4
.IX Item "-d string"
Use the first character of \fIstring\fR as the field delimiter character
instead of the tab character.
.IP "\-f list" 4
.IX Item "-f list"
The \fIlist\fR specifies fields, delimited in the input by a single tab
character.  Output fields are separated by a single tab character.
.IP "\-n" 4
.IX Item "-n"
Do not split multi-byte characters.
.IP "\-s" 4
.IX Item "-s"
Suppresses lines with no field delimiter characters.  Unless
specified, lines with no delimiters are passed through unmodified.
.SH "BUGS"
.IX Header "BUGS"
\&\fBcut\fR does not understand multibyte characters; the \f(CW\*(C`\-c\*(C'\fR and \f(CW\*(C`\-b\*(C'\fR
options function identically, and \f(CW\*(C`\-n\*(C'\fR does nothing.
.SH "STANDARDS"
.IX Header "STANDARDS"
This \fBcut\fR implementation is compatible with the \fIOpenBSD\fR
implementation.
.SH "AUTHOR"
.IX Header "AUTHOR"
The Perl implementation of \fBcut\fR was written by Rich Lafferty,
\&\fIrich@alcor.concordia.ca\fR.
