Her= e's a command I wrote long ago using a different way to deal with optio= ns:

=C2=A0 isee
Usage: isee form= at file ...
=C2=A0 =C2=A0 Display specified inode information for files = passed as arguments.
=C2=A0 =C2=A0 Items of the form ``%X'' in f= ormat will be replaced for these X:
dev inode ino mode nlink uid gid rd= ev size atime
mtime ctime now filename
=C2=A0 =C2=A0 Parenthesized p= rintf-style format specifications can follow a %
=C2=A0 =C2=A0 to overri= de the default format for the various items.
=C2=A0 =C2=A0 %filename is = the name of the current file argument.
=C2=A0 =C2=A0 %now is the time (i= n seconds) when the command started running.
=C2=A0 =C2=A0 The other ite= ms are from the stat structure.

=C2=A0 =C2=A0 Example: isee "%(= 40s)filename: %mtime %mode" /dev/null
=C2=A0 =C2=A0 Show file modif= ication time and mode of /dev/null

inode is just a synonym for ino.

Instead of a kazillion options, the %-stat-fie= ld items identify what you want to see and the printf-style formats = identify how you want them shown. Someone in the Murray Hill library= added strftime formats for date fields, a fine addition, in my view. Addin= g readable user and group names rather than numerical ids would be worth co= nsidering. Maybe having a "rwx"-style form for mode. Sorti= ng can be done by piping the output through sort. Don't get hung up on = shortcomings of the command, just consider how a few familiar concepts and = pipes can be combined to provide a large number of options.

I find it much easier to see the relative size like that.
