Put an ampersand ('&') at the end of the line to run the comamnd in
When you do:
command1 ; command2 ; command3
this runs the commands in series (one after the other, each waiting
for the previous, whereas:
command1 & command2 & command3 &
will put all of them into the background, running them in parallel and
allowing you to continue with additional actions.
This 'multi-tasking' is one of the primary advantages that Unix had
have other operating system designs when it was designed.

I actually do something quite similiar, but I use a 'screen' session
(see GNU Screen) with a '~/.screenrc' that starts IRC in one window,
text-based Email in another terminals in another. Before the
existance of multi-server IRC clients, it actually started several IRC
clients in parallel screens, each talking to a different server.
That bit is still there in the config file, commented out:
#screen -t "#jxxxxx" 3 epic4 -n sladen -c \#jump irc.jxxxxx.org.uk
#screen -t "#qxxxxx" 4 epic4 -n sladen -c \#quaker mxxxxxx.xxxx.xxxx
#screen -t "#uxxxxx" 5 epic4 -n sladen -c \#uxxxxx ircnet.easynet.co.uk
This allows having just one 'gnome-terminal' open, but with multiple
tasks within it and being able to 'alt-tab' between them using Ctrl-a.
Hope that's useful!
