.SH DESCRIPTION
.sp
.LP
Use the \fBcut\fR utility to cut out columns from a table or fields from each
line of a file; in data base parlance, it implements the projection of a
relation. The fields as specified by \fIlist\fR can be fixed length, that is,
character positions as on a punched card (\fB-c\fR option) or the length can
vary from line to line and be marked with a field delimiter character like TAB
(\fB-f\fR option). \fBcut\fR can be used as a filter.
.sp
.LP
Either the \fB-b\fR, \fB-c\fR, or \fB-f\fR option must be specified.
.sp
.LP
Use \fBgrep\fR(1) to make horizontal ``cuts'' (by context) through a file, or
\fBpaste\fR(1) to put files together column-wise (that is, horizontally). To
reorder columns in a table, use \fBcut\fR and \fBpaste\fR.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.mk
.na
\fB\fIlist\fR \fR
.ad
.RS 13n
.rt  
A comma-separated or blank-character-separated list of integer field numbers
(in increasing order), with optional \fB\(mi\fR to indicate ranges (for
instance, \fB1,4,7\fR; \fB1\(mi3,8\fR; \fB\(mi5,10\fR (short for
\fB1\(mi5,10\fR); or \fB3\(mi\fR (short for third through last field)).
.RE

.sp
.ne 2
.mk
.na
\fB\fB\fR\fB-b\fR \fIlist\fR \fR
.ad
.RS 13n
.rt  
The \fIlist\fR following \fB-b\fR specifies byte positions (for instance,
\fB-b1\fR\fB-72\fR would pass the first 72 bytes of each line). When \fB-b\fR
and \fB-n\fR are used together, \fIlist\fR is adjusted so that no multi-byte
character is split.
.RE

.sp
.ne 2
.mk
.na
\fB\fB\fR\fB-c\fR \fIlist\fR \fR
.ad
.RS 13n
.rt  
The \fIlist\fR following \fB-c\fR specifies character positions (for instance,
\fB-c1\fR\fB-72\fR would pass the first 72 characters of each line).
.RE

.sp
.ne 2
.mk
.na
\fB\fB\fR\fB-d\fR \fIdelim\fR \fR
.ad
.RS 13n
.rt  
The character following \fB-d\fR is the field delimiter (\fB-f\fR option only).
Default is \fItab\fR. Space or other characters with special meaning to the
shell must be quoted. \fIdelim\fR can be a multi-byte character.
.RE

.sp
.ne 2
.mk
.na
\fB\fB\fR\fB-f\fR \fIlist\fR \fR
.ad
.RS 13n
.rt  
The \fIlist\fR following \fB-f\fR is a list of fields assumed to be separated
in the file by a delimiter character (see \fB-d\fR ); for instance,
\fB-f1\fR\fB,7\fR copies the first and seventh field only. Lines with no field
delimiters will be passed through intact (useful for table subheadings), unless
\fB-s\fR is specified.
.RE

.sp
.ne 2
.mk
.na
\fB\fB-n\fR \fR
.ad
.RS 13n
.rt  
Do not split characters. When \fB-b\fR \fIlist\fR and \fB-n\fR are used
together, \fIlist\fR is adjusted so that no multi-byte character is split.
.RE

.sp
.ne 2
.mk
.na
\fB\fB-s\fR \fR
.ad
.RS 13n
.rt  
Suppresses lines with no delimiter characters in case of \fB-f\fR option.
Unless specified, lines with no delimiters will be passed through untouched.
.RE

.SH OPERANDS
.sp
.LP
The following operands are supported:
.sp
.ne 2
.mk
.na
\fB\fIfile\fR \fR
.ad
.RS 9n
.rt  
A path name of an input file. If no \fIfile\fR operands are specified, or if a
\fIfile\fR operand is \fB\(mi\fR, the standard input will be used.
.RE

.SH USAGE
.sp
.LP
See \fBlargefile\fR(5) for the description of the behavior of \fBcut\fR when
encountering files greater than or equal to 2 Gbyte (2^31 bytes).
.SH EXAMPLES
.LP
\fBExample 1 \fRMapping user IDs
.sp
.LP
A mapping of user \fBIDs\fR to names follows:

.sp
.in +2
.nf
example% \fBcut -d: -f1,5 /etc/passwd\fR
.fi
.in -2
.sp

.LP
\fBExample 2 \fRSetting current login name
.sp
.LP
To set \fBname\fR to current login name:

.sp
.in +2
.nf
example$ \fBname=\(gawho am i | cut -f1 -d' '\(ga\fR
.fi
.in -2
.sp

.SH ENVIRONMENT VARIABLES
.sp

that affect the execution of \fBcut\fR: \fBLANG\fR, \fBLC_ALL\fR,
\fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
