The browser treats the "whatever:" as a protocol to follow, that's why it's showing them to you as links

The funny thing is that it rejects "whatever::"...

"unset a

This is clearing the "a" variable

echo " $a=$(who) "

This is echoing to the terminal the expansion of the "a" variable (which you just cleared a line above!) as well as a "=" sign followed by the output of the "who" command.

What you are trying to do is:

unset a

a="$(who)"

echo "$a"

However, why don't you just do:

function a { who }

Well, I have no idea how Limpus Linux works (in fact, I hadn't heard of it until you talked about it).

Anyway, I can assure you Fedora, Opensuse or Ubuntu are pretty straightforward: click,click,click and you are done with everything :)

Why don't you just install a different linux like Fedora, Ubuntu, OpenSuse...

Well, that's the "beauty" of the closed source software if they use "tied up" approach. Eventually people will realize that's not acceptable... I'm losing myself here, you get my point though ;)

Evolution or thunderbird might work for you
