numfmt - numfmt
NAME SYNOPSIS DESCRIPTION OPTIONSNAME
numfmt − numfmt
SYNOPSIS
numfmt [OPTION]... [NUMBER]...
DESCRIPTION
Convert numbers from/to human−readable strings
OPTIONS
−d, −−delimiter <X>
use X instead of whitespace for field delimiter
−−field <FIELDS>
replace the numbers in these input fields; see FIELDS below [default: 1]
−−format <FORMAT>
use printf style floating−point FORMAT; see FORMAT below for details
−−from <UNIT>
auto−scale input numbers to UNITs; see UNIT below [default: none]
−−from−unit <N>
specify the input unit size [default: 1]
−−to <UNIT>
auto−scale output numbers to UNITs; see UNIT below [default: none]
−−to−unit <N>
the output unit size [default: 1]
−−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>
use METHOD for rounding when scaling [default: from−zero] [possible values: up, down, from−zero, towards−zero, nearest]
−−suffix <SUFFIX>
print SUFFIX after each formatted number, and accept inputs optionally ending with SUFFIX
−−invalid <INVALID>
set the failure mode for invalid input [default: abort] [possible values: abort, fail, warn, ignore]
−z, −−zero−terminated
line delimiter is NUL, not newline
−h, −−help
Print help
−V, −−version
Print version
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.
