Section (1) numfmt
Name
numfmt — Convert numbers from/to human-readable strings
Synopsis
numfmt
[OPTION
...] [NUMBER
...]
DESCRIPTION
Reformat NUMBER(s), or the numbers from standard input if none are specified.
Mandatory arguments to long options are mandatory for short options too.
−−debug
-
print warnings about invalid input
−d
,−−delimiter
=X/-
use X instead of whitespace for field delimiter
−−field
=FIELDS/-
replace the numbers in these input fields (default=1) see FIELDS below
−−format
=FORMAT/-
use printf style floating−point FORMAT; see FORMAT below for details
−−from
=UNIT/-
auto−scale input numbers to UNITs; default is _zsingle_quotesz_none_zsingle_quotesz_; see UNIT below
−−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 can be: abort (default), fail, warn, 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 can be: up, down, from−zero (default), towards−zero, nearest
−−suffix
=SUFFIX/-
add SUFFIX to output numbers, and accept optional SUFFIX in input numbers
−−to
=UNIT/-
auto−scale output numbers to UNITs; see UNIT below
−−to−unit
=N/-
the output unit size (instead of the default 1)
−z
,−−zero−terminated
-
line delimiter is NUL, not newline
−−help
-
display this help and exit
−−version
-
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_zsingle_quotesz_th field, counted from 1
- N−
-
from N_zsingle_quotesz_th field, to end of line
- N−M
-
from N_zsingle_quotesz_th to M_zsingle_quotesz_th field (inclusive)
−M
-
from first to M_zsingle_quotesz_th field (inclusive)
- −
-
all fields
Multiple fields/ranges can be separated with commas
FORMAT must be suitable for printing one
floating−point argument _zsingle_quotesz_%f_zsingle_quotesz_. Optional quote (%_zsingle_quotesz_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 status 2. With −−invalid=
_zsingle_quotesz_fail_zsingle_quotesz_ a warning is
printed for each conversion error and the exit status is 2.
With −−invalid=
_zsingle_quotesz_warn_zsingle_quotesz_ each
conversion error is diagnosed, but the exit status is 0.
With −−invalid=
_zsingle_quotesz_ignore_zsingle_quotesz_ conversion
errors are not diagnosed and the exit status is 0.
EXAMPLES
$ 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
