CUT

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

Using cut to facilitate a zone transfer. host will list host information
and the 4th item on each line is the IP addresses of the host. Using a
pipe and host, we can only extract the IP addresses.

	host -l isp.net | cut '-d ' -f 4

Other uses:

	echo $LOGNAME | cut -c1-1

Switches:

  -d, --delimiter=DELIM   use DELIM instead of TAB for field delimiter
  -s, --only-delimited    do not print lines not containing delimiters

  -b, --bytes=LIST        output only these bytes
  -c, --characters=LIST   output only these characters
  -f, --fields=LIST       output only these fields

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.
