I am using Linux, and I would like to be able to programmatically open notebooks in a running Mathematica instance from the command line. Currently, doing something like

/opt/Wolfram/Mathematica/8.0/Executables/Mathematica foo.nb

launches a new kernel/frontend instance. Is it possible to re-use a running frontend for opening notebooks (short of enforcing single-instance behavior, for which I believe there is a command line option)?

You can start Mathematica with :

/opt/Wolfram/Mathematica/8.0/Executables/Mathematica -sl &

and then open your notebook in the same session with :

/opt/Wolfram/Mathematica/8.0/Executables/Mathematica -sl foo.nb

From the man page Mathematica --help :

-sl (--singlelaunch): Open in an existing process, if possible.

Yes, the -sl flag does the trick. Another instance of Mathematica can still be launched by omitting the flag; opening notebooks afterwards with the -sl flag will still be bringing them up in the first instance –  Leo Alekseyev Oct 27 '12 at 20:19
