Newbie basher question:

I'd like to assign the output of the following line to a shell script variable:
'xauth list :0'

For background, here are the steps I type into a terminal that I'm trying to put in a bash file:

xauth list :0
(the output shows the current unix:0 MIT-MAGIC-COOKIE-1 value: e95ea........47a, which I then add to xauth)
xauth add :0 MIT-MAGIC-COOKIE-1 e95ea.......47a
export DISPLAY=:0
java -jar selenium-server.jar

Any ideas on how to send the output of 'xauth list :0' to a variable?

Thanks

depends abit on what type of output is given from xauth, but i would try this:


It's standard "executing programs in a variable"-bash syntax also you can use "backticks" which is done like this:


Both does the same in bash, but the $() is easier to read IMHO.
