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

Syntax
       cut -clist [file1 file2...]
       cut -flist [-dchar] [-s] [file1 file2...]

Description
       Use  the	 command  to  cut out columns from a table or fields from each
       line of a file.	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).  The command can be used as a filter.
       If no files are given, the standard input is used.

       Use to make horizontal ``cuts'' (by context) through a file, or to  put
       files together in columns.  To reorder columns in a table, use and

Options
       list	   Specifies  ranges  that  must  be a comma-separated list of
		   integer field numbers in increasing order.  With optional -
		   indicates  ranges  as  in  the -o option of nroff/troff for
		   page ranges; for example, 1,4,7; 1-3,8;  -5,10  (short  for
		   1-5,10); or 3- (short for third through last field).

       -clist	   Specifies  character positions to be cut out.  For example,
		   -c1-72 would pass the first 72 characters of each line.

       -flist	   Specifies the fields to be cut  out.	  For  example,	 -f1,7
		   copies  the	first  and  seventh field only.	 Lines with no
		   field delimiters are passed through intact (useful for  ta‐
		   ble subheadings), unless -s is specified.

       -dchar	   Uses	 the  specified	 character  as	the  field  delimiter.
		   Default is tab.  Space or  other  characters	 with  special
		   meaning to the shell must be quoted.	 The -d option is used
		   only in combination with the -f option, according  to  XPG3
		   and SVID2/SVID3.

       -s	   Suppresses  lines  with  no	delimiter  characters.	Unless
		   specified, lines with  no  delimiters  are  passed  through
		   untouched.  Either the -c or -f option must be specified.

Examples
       Mapping of user IDs to names:
       cut -d: -f1,5 /etc/passwd
       To set name to the current login name for the csh shell:
       set name=`who am i | cut -f1 -d" "`
       To set name to the current login name for the sh, sh5, and ksh shells:
       name=`who am i | cut -f1 -d" "`

Diagnostics
       "line too long"	   A  line  can	 have  no  more than 511 characters or
			   fields.

       "bad list for c/f option"
			   Missing -c or -f option  or	incorrectly  specified
			   list.   No  error occurs if a line has fewer fields
			   than the list calls for.

       "no fields"	   The list is empty.
