|
.SH RATIONALE
|
|
|
|
With the assumption that tools will output data separated with ASCII field
|
|
separators, there is
|
|
|
|
The idea for this utility originated in the fact that GNU ls(1) utility contains
|
|
a
|
|
.B -h
|
|
option which enables human-readable units in file size outputs. This
|
|
functionality was broken out into hru(1), but there was no easy way to modify
|
|
the field in the ouput of ls(1p) without a new tool.
