The question does not have to be directly related to Linux and any language is fair game.

alias startdwm="export MYWM=dwm & startx"


I had made some aliases to my .profile that would create a variable to be used in my .xinitrc file, for trying some new things out, and I found that when I use the aliases I created such as the title of this thread the variable MYWM doesn't get created or changed. I'm thinking that & should not be used here.

Also, unfortunately, I wasn't able to find anything that explained this, or even a listing of bash symbols...Well, I did find one, but it was about how to enter those symbols as characters not what they did.

.profile
Code:
alias startdwm="export MYWM=dwm & startx"
alias startobdwm="export MYWM=openboxdwm & startx"
alias startopenbox="export MYWM=NA & startx"
alias startratpoison="export MYWM=ratpoison & startx"

.xinitrc
Code:
if [ $MYWM = variablename ]
then
    exec windowmanager
fi
(Rather than list every single if statement, I'll just write that, keeping it easy to read, )

Thanks upfront...

P.S. For future reference, would anything that is related to scripting belong in the programming section of LQ or would a question like this belong elsewhere?

To export a variable, use a function instead:
Code:
function startdwm() {
  export MYWM=dwm
  startx
}
Note that & is used to runn commands in background and it is actually not needed to export a variable in background. To run more commands in sequence you can use a semi-colon (the commands separator) or eventually && (which means "if the previous command run successfully then run the following command).
