       numfmt -	Convert	numbers	from/to	human-readable strings

       numfmt [OPTION]... [NUMBER]...

       Reformat	 NUMBER(s),  or	 the  numbers  from standard input if none are

       Mandatory arguments to long options are	mandatory  for	short  options

	      print warnings about invalid input

       -d, --delimiter=X
	      use X instead of whitespace for field delimiter

	      replace the numbers in these input fields	(default=1) see	FIELDS

	      use printf style floating-point FORMAT; see FORMAT below for de-

	      auto-scale  input	 numbers to UNITs; default is 'none'; see UNIT

	      specify the input	unit size (instead of the default 1)

	      use locale-defined grouping of  digits,  e.g.  1,000,000	(which
	      means it has no effect in	the C/POSIX locale)

	      print  (without converting) the first N header lines; N defaults
	      to 1 if not specified

	      failure mode for invalid numbers:	MODE can be: abort  (default),
	      fail, warn, ignore

	      pad  the	output	to  N characters; positive N will right-align;
	      negative N will left-align; padding is ignored if	the output  is
	      wider  than  N;  the default is to automatically pad if a	white-
	      space is found

	      use METHOD for rounding when scaling; METHOD can be:  up,	 down,
	      from-zero	(default), towards-zero, nearest

	      add  SUFFIX to output numbers, and accept	optional SUFFIX	in in-
	      put numbers

	      auto-scale output	numbers	to UNITs; see UNIT below

	      the output unit size (instead of the default 1)

       -z, --zero-terminated
	      line delimiter is	NUL, not newline

       --help display this help	and exit

	      output version information and exit

   UNIT	options:
       none   no auto-scaling is done; suffixes	will trigger an	error

       auto   accept optional single/two letter	suffix:

	      1K = 1000, 1Ki = 1024, 1M	= 1000000, 1Mi = 1048576,

       si     accept optional single letter suffix:

	      1K = 1000, 1M = 1000000, ...

       iec    accept optional single letter suffix:

	      1K = 1024, 1M = 1048576, ...

       iec-i  accept optional two-letter suffix:

	      1Ki = 1024, 1Mi =	1048576, ...

   FIELDS supports cut(1) style	field ranges:
       N      N'th field, counted from 1

       N-     from N'th	field, to end of line

       N-M    from N'th	to M'th	field (inclusive)

       -M     from first to M'th field (inclusive)

       -      all fields

       Multiple	fields/ranges can be separated with commas

       FORMAT must be suitable for printing one	floating-point argument	 '%f'.
       Optional	 quote	(%'f)  will enable --grouping (if supported by current
       locale).	 Optional width	value (%10f) will pad  output.	Optional  zero
       (%010f)	width  will  zero  pad	the  number.  Optional negative	values
       (%-10f) will left align.	 Optional precision (%.1f) will	 override  the
       input determined	precision.

       Exit  status is 0 if all	input numbers were successfully	converted.  By
       default,	numfmt will stop at the	first conversion error with exit  sta-
       tus  2.	With --invalid='fail' a	warning	is printed for each conversion
       error and the exit status is 2.	With --invalid='warn' each  conversion
       error  is diagnosed, but	the exit status	is 0.  With --invalid='ignore'
       conversion errors are not diagnosed and the exit	status is 0.

	      $	numfmt --to=si 1000

	      -> "1.0K"

	      $	numfmt --to=iec	2048

	      -> "2.0K"

	      $	numfmt --to=iec-i 4096

	      -> "4.0Ki"

	      $	echo 1K	| numfmt --from=si

	      -> "1000"

	      $	echo 1K	| numfmt --from=iec

	      -> "1024"

	      $	df -B1 | numfmt	--header --field 2-4 --to=si
	      $	ls -l  | numfmt	--header --field 5 --to=iec
	      $	ls -lh | numfmt	--header --field 5 --from=iec --padding=10
	      $	ls -lh | numfmt	--header --field 5 --from=iec --format %10f
