CUT(1)				   BSD General Commands Manual				   CUT(1)

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

SYNOPSIS
     cut -b list [-n] [file ...]
     cut -c list [file ...]
     cut -f list [-d delim] [-s] [file ...]

DESCRIPTION
     The cut utility cuts out selected portions of each line (as specified by list) from each
     file and writes them to the standard output.  If no file arguments are specified, or a file
     argument is a single dash ('-'), cut reads from the standard input.  The items specified by
     list can be in terms of column position or in terms of fields delimited by a special charac-
     ter.  Column numbering starts from 1.

     The list option argument 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
     last 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.

     The options are as follows:

     -b list
	     The list specifies byte positions.

     -c list
	     The list specifies character positions.

     -d delim
	     Use delim as the field delimiter character instead of the tab character.

     -f list
	     The list specifies fields, separated in the input by the field delimiter character
	     (see the -d option).  Output fields are separated by a single occurrence of the
	     field delimiter character.

     -n      Do not split multi-byte characters.  Characters will only be output if at least one
	     byte is selected, and, after a prefix of zero or more unselected bytes, the rest of
	     the bytes that form the character are selected.

     -s      Suppress lines with no field delimiter characters.  Unless specified, lines with no
	     delimiters are passed through unmodified.

ENVIRONMENT
     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of cut as described
     in environ(7).

EXIT STATUS
     The cut utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     Extract users' login names and shells from the system passwd(5) file as ``name:shell''
     pairs:

	   cut -d : -f 1,7 /etc/passwd

     Show the names and login times of the currently logged in users:

	   who | cut -c 1-16,26-38

SEE ALSO
     colrm(1), paste(1)

STANDARDS
     The cut utility conforms to IEEE Std 1003.2-1992 (``POSIX.2'').

     A cut command appeared in AT&T System III UNIX.
