Rc forks a new process for every [non builtin] command it runs. To
avoid such, use the . command to source the script instead of running
it.
Ok. The thing about forking is clear. Yes, your suggestion of using . would
'solve' the problem of seeing the variables set in the 'a' script (called

Hello,
If I have an rc script and I don't specify any rfork in it, then the
namespace and the environment should be shared.
So, having an 'a' script
#!/bin/rc
a = hello
cd c #later on...
and a 'b' script:
#!/bin/rc
a
echo $a
and
Drawterm for Linux(I currently run Arch Linux) doesn't allow me to use
the middle mouse button emulation(Shift + right mouse button).
For example if I run Acme, I can't exec any command via middle button
emulation. There is simply no reaction. Is there any known bug?
Drawterm for Windows works
if you want to re-get the value of an environment variable,
you can do:
ifs=() var=`{cat /env/var}
Ok. So if one wants to update the rc's view of the environment, one must
write sth. along the lines
for(var in `{ls /env}) {
ifs=() contents = `{cat /env/$var}
if (~ $var *#*) fn
for(var in `{ls /env}) {
ifs=() contents = `{cat /env/$var}
if (~ $var *#*) fn `{echo $var | awk '{split($0, a, #); print a[1]}'}
{$contents}
if not var = $contents
}
pretty sure that's a syntax error. and for simple variables, quite
wrong. this function does better, but still
the easy (and correct) answer is
exec rc

Well but this you can't do when being in the middle of a script
execution...
Can you?

Hi folks,
did anyone already do some research on running 9P directly via
serial or USB links as interface for embedded devices, eg. digicams ?
I'm currently advertising an students project for developing an
gphoto2-fileserver, so a wide range of digicams (which do not
support usb mass storage
There already is a gphoto2 fs for fuse if I remember correctly. Though
I haven't heard of any camera with 9p yet.
But it's late and perhaps I misunderstand you.

there is gphoto2 for 9p -- it was in the npfs repository for more than
4 years. I haven't checked it recently so I don't know if it still
compiles.
