NAME
       cut - cut out selected fields of each line of a file

SYNOPSIS
       cut -b list [-n] [file...]

       cut -c list [file...]

       cut -f list [-d delim] [-s] [file...]

DESCRIPTION
       Use the cut 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 list can be fixed length, that is, character positions as on a punched card (-c  option)  or  the
       length can vary from line to line and be marked with a field delimiter character like <TAB> (-f option). cut can be used as a filter.

       Either the -b, -c, or -f option must be specified.

       Use grep(1) to make horizontal ``cuts'' (by context) through a file, or paste(1) to put files together column-wise (that is, horizontally).
       To reorder columns in a table, use cut and paste.

OPTIONS
       The following options are supported:

       list	       A comma-separated or blank-character-separated list of integer field numbers (in increasing  order),  with  optional  -	to
		       indicate ranges (for instance, 1,4,7; 1-3,8; -5,10 (short for 1-5,10); or 3- (short for third through last field)).

       -b list	       The  list  following -b specifies byte positions (for instance, -b1-72 would pass the first 72 bytes of each line). When -b
		       and -n are used together, list is adjusted so that no multi-byte character is split.

       -c list	       The list following -c specifies character positions (for instance, -c1-72 would pass the first 72 characters of each line).

       -d delim        The character following -d is the field delimiter (-f option only). Default is tab. Space or other characters with  special
		       meaning to the shell must be quoted. delim can be a multi-byte character.

       -f list	       The  list  following  -f  is  a	list of fields assumed to be separated in the file by a delimiter character (see -d ); for
		       instance, -f1,7 copies the first and seventh field only. Lines with no field delimiters will be passed through intact (use-
		       ful for table subheadings), unless -s is specified.

       -n	       Do not split characters. When -b list and -n are used together, list is adjusted so that no multi-byte character is split.

       -s	       Suppresses  lines  with	no  delimiter  characters in case of -f option. Unless specified, lines with no delimiters will be
		       passed through untouched.

OPERANDS
       The following operands are supported:

       file	       A path name of an input file. If no file operands are specified, or if a file operand is -,  the  standard  input  will	be
		       used.

USAGE
       See largefile(5) for the description of the behavior of cut when encountering files greater than or equal to 2 Gbyte (2**31 bytes).

EXAMPLES
       Example 1: Mapping user IDs

       A mapping of user IDs to names follows:

       example% cut -d: -f1,5 /etc/passwd

       Example 2: Setting current login name

       To set name to current login name:

       example$ name=`who am i | cut -f1 -d' '`

ENVIRONMENT VARIABLES
       See  environ(5)	for  descriptions of the following environment variables that affect the execution of cut: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS
       The following exit values are returned:

       0	All input files were output successfully.

       >0	An error occurred.

ATTRIBUTES
       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

DIAGNOSTICS
       cut: -n may only be used with -b

       cut: -d may only be used with -f

       cut: -s may only be used with -f

       cut: cannot open <file>		       Either file cannot be read or does not exist.  If multiple files are present, processing continues.

       cut: no delimiter specified	       Missing delim on -d option.

       cut: invalid delimiter

       cut: no list specified		       Missing list on -b, -c, or -f option.

       cut: invalid range specifier

       cut: too many ranges specified

       cut: range must be increasing

       cut: invalid character in range

       cut: internal error processing input

       cut: invalid multibyte character

       cut: unable to allocate enough memory
