OK, let me dissapoint you (no offence intended).
In unix there are NO "commands", those are "requests" from simple
applications to perform some acts.

Really? I use dozens, if not hundreds, of commands.

Switches? That DOS talk; you mean 'options'.

Unfortunately, the Free Software Foundation doesn't like man
pages and often provides full documentation only in the clunky
info format.

There is no "definitive" Unix. The closest there is is the Single
Unix Specification, which GNU/Linux and other *nix variants
follow with varying degrees of compliance.

There are far more details than can be covered in a single book.
For use of Unix commands, you can learn a lot from the archives
of the comp.unix.shell newsgroup.

So when you have an app under one in this crowd learn just this one, it
maybe the same one in every one of them or it maybe different.

The best place to look is the Single Unix Specification. With a
few exceptions, you can't go far wrong using the standard syntax:

What's "bash"? If I were in your situation, I'd type "unrar e
tripcancun1.rar" Notice, there's only one space between the unrar, the e,
and the file name (if you're in the directory, you don't need to type the
absolute path). Actually, instead of typing out "tripcancun1.rar," I
would have typed "t<tab>1<tab>" -- helps to prevent typos.
HTH,

Rusty,
I am able to do this easily from within Ark. I have plf unrar installed. I
select the first archive choose the 'all' option within Ark, then unzip
into the directory of choice. It seems to find the other .rar archives
fine if they are in the same directory.

Thanks Robert, ARK worked for me also.

You gave a command in CLI and bash responded by giving you the "help"
sentence as the command had parts (switches) missing.
So the best would be to go to "man rar" or "man unrar" (no quotes) and
get all the wisdom from there.

Did you actually type 'bash'? If so, you don't need it. At the command
prompt just type:
unrar e /email/fun/temp/tripcancun1.rar
That should work fine.
