Shell command: numfmt

numfmt converts numbers from and/or to human readable representations:

numfmt [OPTION]… [NUMBER]…

Options

	`--debug`		print warnings about invalid input
`-d`	`--delimiter=`	`X`	use `X` instead of whitespace for field delimiter
	`--field=`	`FIELD`	replace the numbers in these input fields (default=1).
	`--format=FORMAT`		use printf style floating-point `FORMAT`
	`--from=UNIT`		auto-scale input numbers to UNITs; `UNIT` is `auto`, `si`, `iec` or `iec-i` default is 'none'.
	`--from-unit=N`		specify the input unit size (instead of the default 1)
	`--grouping`		use locale-defined grouping of digits, e.g. 1,000,000 (which means it has no effect in the C/POSIX locale)
	`--header[=]`	`N`	print (without converting) the first `N` header lines. `N` defaults to 1 if not specified
	`--invalid=`	`MODE`	failure mode for invalid numbers. `MODE` is `abort` (default), `fail`, `warn` or `ignore`
	`--padding=`	`N`	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 whitespace is found
	`--round=`	`METHOD`	use `METHOD` for rounding when scaling; METHOD is `up`, `down`, `from-zero` (default), `towards-zero` or `nearest`
	`--suffix=`	`SUFFIX`	add `SUFFIX` to output numbers and accept optional `SUFFIX` in input numbers
	`--to=`	`UNIT`	auto-scale output numbers to `UNIT`. `UNIT` is `none`, `si`, `iec` or `iec-i`
	`--to-unit=`	`N`	the output unit size (instead of the default 1)
`-z`	`--zero-terminated`		line delimiter is `NUL` (not newline)
	`--help`
	`--version`

Examples

Specifying UNIT with --to

$ numfmt 1024 --to none
1024

$ numfmt 1024 --to si
1.1 K

$ numfmt 1024 --to iec
1.0 K

$ numfmt 1024 --to iec-i
1.0 Ki

Specifying UNIT with --from

$ numfmt  1K  --from auto
1000

$ numfmt  1K  --from si
1000

$ numfmt  1K  --from iec
1024

$ numfmt  1Ki --from iec-i
1024

Using fields

$ echo 'abc  12345  67890  def' | numfmt --to iec
numfmt: invalid number: ‘abc’

$ echo 'abc  12345  67890  def' | numfmt --to iec --field 2
abc    13K  67890  def

$ echo 'abc  12345  67890  def' | numfmt --to iec --field 2,3
abc    13K  67K  def

Specifying a format

$ numfmt 12345 --to iec
13K

$ numfmt 12345 --to iec --format %3.2f
12.06K

Report the size of the hibernation image:

$ cat /sys/power/image_size
26840137728
$ cat /sys/power/image_size | numfmt --to iec
25G
