-h not working for 'ls' command in Sun SPARC

Question

I was trying this command for listing files in human readable form:

$ ls -lh                                                                                                                                         
ls: illegal option -- h
usage: ls -1RaAdCxmnlogrtucpFbqisfL [files]

Is there a way to enable it?

I am using Sun SPARC:

$ uname -a

Answer 1

The GNU version of ls can be found in the coreutils package at Sun Freeware.

Answer 2

Probably not whilst still using Solaris 8, you'll probably need to upgrade to get that functionality.
