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

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

       cut -c list [file]...

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

       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.

       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

       -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 (useful 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.

       The following operands are supported:

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

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

       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' '`

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

       The following exit values are returned:

       0      All input files were output successfully.

       >0     An error occurred.

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

       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |Availability		     |SUNWcsu			   |
       |CSI			     |Enabled			   |
       |Interface Stability	     |Standard			   |

       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, process-
	   ing 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
