Umm...why are you posting this in a cadence group?
Funny, i was thinking of doing such a thing also...
One way i can see i using ipcSkillProcess() to start an external process.
I don't think this can be done using public SKILL functions.

Yes.
Linux is... different. With the direction that X.org is taking X11, I
is it possible to write a script (in skill?) which will start the
spectre netlister?
I would like to have a script which starts the netlister instead of
going through the menus.
Funny, i was thinking of doing such a thing also...
I'm joining a script which i quickly did at the bottom of this post.
I didn't test it toroughly, though. feel free to post
comment/corrections/improvements.
Feel free to code a gui also
Is it possible to force the execution of a skill script inside Cadence
from the linux/unix command prompt? This would allow an external
program to take 'control' over Cadence. Can this be done? When can I
find more information on this?
One way i can see i using ipcSkillProcess() to start an external process.
when launched this way, file handles 3 and 4 of the newly created process
are open for SKILL communication, that is, the process can send SKILL
command
to port 3 and get the output from port 4.
in this way however, the execution is triggered from inside cadence. to
do the opposite
one has to run a "daemon" SKILL script which opens a socket, waits for
commands and executes them.
this has been discussed previously, and Andrew even posted the code to
do it. see
