CUT(1)									FSF								    CUT(1)

NAME

       cut - remove sections from each line of files

SYNOPSIS

       cut [OPTION]... [FILE]...

DESCRIPTION

       Print selected parts of lines from each FILE to standard output.

       Mandatory arguments to long options are mandatory for short options too.

       -b, --bytes=LIST
	      output only these bytes

       -c, --characters=LIST
	      output only these characters

       -d, --delimiter=DELIM
	      use DELIM instead of TAB for field delimiter

       -f, --fields=LIST
	      output only these fields;  also print any line that contains no delimiter character, unless the -s option is specified

       -n     with -b: don't split multibyte characters

       -s, --only-delimited
	      do not print lines not containing delimiters

       --output-delimiter=STRING
	      use STRING as the output delimiter the default is to use the input delimiter

       --help display this help and exit

       --version
	      output version information and exit

       Use one, and only one of -b, -c or -f.  Each LIST is made up of one range, or many ranges separated by commas.  Each range is one of:

       N      N'th byte, character or field, counted from 1

       N-     from N'th byte, character or field, to end of line

       N-M    from N'th to M'th (included) byte, character or field

       -M     from first to M'th (included) byte, character or field

       With no FILE, or when FILE is -, read standard input.
