$ 7z a foo.izo

creates a foo.7z which in my case is mostly 6 times smaller or roughly
600% efficient.

$ 7z e foo.7z

decompresses it.

Also known as p7zip it is fantastic. No comparison with bzip2 or gzip.
Of course bzip2 never
enjoyed much patronage anyway.

You also have zip and compress in UNIX by the way.

One more tip. Think of this as a "tiplet" like booklet.

$ ldd `which bash`

will give you the shared libraries bash is linked against.

You surely want to do

$ ldd `which convert`

If a library is found missing you can be sure that executable is not
going to work.

You also know what to do to copy executables from one machine to another.

By the way ` is backquote on the top left corner of your keyboard.

I promise not to give 2 tips like this any other day.

But this 7z is surely something worth trying. It is amazing and I
really wonder when it will
become widespread and get built into gzip executable... or tar
