NAME¶

numfmt - Convert numbers from/to human-readable strings

SYNOPSIS¶

numfmt [--debug] [-d|--delimiter] [--field] [--format] [--from] [--from-unit] [--to] [--to-unit] [--padding] [--header] [--round] [--suffix] [--unit-separator] [--invalid] [-z|--zero-terminated] [-h|--help] [-V|--version] [NUMBER]

DESCRIPTION¶

Convert numbers from/to human-readable strings

OPTIONS¶

--debug

numfmt-help-debug

-d, --delimiter <X>

use X instead of whitespace for field delimiter

--field <FIELDS> [default: 1]

replace the numbers in these input fields; see FIELDS below

--format <FORMAT>

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

--from <UNIT> [default: none]

auto-scale input numbers to UNITs; see UNIT below

--from-unit <N> [default: 1]

specify the input unit size

--to <UNIT> [default: none]

auto-scale output numbers to UNITs; see UNIT below

--to-unit <N> [default: 1]

the output unit size

--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

--header [<N>]

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

--round <METHOD> [default: from-zero]

use METHOD for rounding when scaling

[possible values: up, down, from-zero, towards-zero, nearest]

--suffix <SUFFIX>

print SUFFIX after each formatted number, and accept inputs optionally ending with SUFFIX

--unit-separator <STRING>

numfmt-help-unit-separator

--invalid <INVALID> [default: abort]

set the failure mode for invalid input

[possible values: abort, fail, warn, ignore]

-z, --zero-terminated

line delimiter is NUL, not newline

-h, --help

Print help

-V, --version

Print version

EXTRA¶

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.

VERSION¶

v(uutils coreutils) 0.7.0

EXAMPLES¶

Convert 1.5K (SI Units) to 1500:

numfmt --from si 1.5K

Convert 1500 to 1.5K (SI Units):

numfmt --to si 1500

Convert 1.5K (IEC Units) to 1536:

numfmt --from iec 1.5K

Use appropriate conversion based on the suffix:

numfmt --from auto 1.5Ki

Convert 5th field (1-indexed) to IEC Units without converting header:

ls -l | numfmt --header=1 --field 5 --to iec

Convert to IEC units, pad with 5 characters, left aligned:

du [-s|--summarize] * | numfmt --to iec --format "%-5f"
