.SH NAME
hru \(en human readable units

.SH SYNOPSIS

hru
.\"
.SH DESCRIPTION

Convert counts to higher units.

Byte counts will be read in the form of whole numbers from the standard input
and be written to the standard output the same number converted to a higher unit
of data as defined by the \fIInternational System of Units\fP.

The program will convert the byte count to the highest unit possible where the
value is greater than one.
.\"
.SH DIAGNOSTICS

If encountering non-integer characters in the standard input, the program will
exit with the appropriate error code as defined by
.BR sysexits.h (3)
and print an error message.
.\"
.SH RATIONALE

The GNU project\(cqs
.BR ls (1)
implementation contains a human-readable option (\fB-h\fP) that, when specified,
makes the tool print size information in a format more immediately
readable. This functionality is useful not only in this context, so the decision
was made to split it into a new tool. The original functionality from GNU\(cqs
.BR ls (1)
can be emulated with
.BR fop (1)
combined with this program.
.\"
.SH STANDARDS

The standard unit prefixes as specified by the
.I Bureau International des Poids et Mesures
.RI ( BIPM )
in the ninth edition of
.I The International System of Units
.RI ( SI )
are utilized for the ouput of conversions.
