SYNOPSIS
numfmt [--debug] [--grouping] [-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
    print warnings about invalid input

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

-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>
    use STRING to separate the number from any unit when printing; by default, no separator is used

--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.
