NUMFMT(1)                        User Commands                       NUMFMT(1)

       numfmt - Convert numbers from/to human-readable strings

       numfmt [OPTION]... [NUMBER]...

       Reformat  NUMBER(s),  or  the  numbers  from standard input if none are

       Mandatory arguments to long options are  mandatory  for  short  options

              print warnings about invalid input

       -d, --delimiter=X
              use X instead of whitespace for field delimiter

              replace the number in input field N (default is 1)

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

              auto-scale input numbers to UNITs; default is 'none';  see  UNIT

              specify the input unit size (instead of the default 1)

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

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

              failure  mode for invalid numbers: MODE can be: abort (default),
              fail, warn, ignore

              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  white-
              space is found

              use  METHOD  for rounding when scaling; METHOD can be: up, down,
              from-zero (default), towards-zero, nearest

              add SUFFIX to output numbers,  and  accept  optional  SUFFIX  in
              input numbers

              auto-scale output numbers to UNITs; see UNIT below

              the output unit size (instead of the default 1)

       --help display this help and exit

              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, ...

       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.

       Exit  status is 0 if all input numbers were successfully converted.  By
       default, numfmt will stop at the first conversion error with exit  sta-
       tus  2.  With --invalid='fail' a warning is printed for each conversion
       error and the exit status is 2.  With --invalid='warn' each  conversion
       error  is diagnosed, but the exit status is 0.  With --invalid='ignore'
       conversion errors are not diagnosed and the exit status is 0.

              $ 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 | numfmt --header --field 2 --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
