How does a graphical interface like the DDD (Data Display Debugger)
interact with gdb (GNU debugger)? I mean, I don't think the people
that maintain gdb modified the source code so that it accompany coders
that wanted to add a graphical interface to a text based program.

Hello-

I recently got bit by this issue in some of my shell scripts... it
seems that writing to /dev/stdout does not work if you have su'd to a
different user. (This is on debian.) It seems this is because /dev/
stdout is a symlink to /proc/self/fd/1, in turn a symlink to /dev/
pts/..., which only has write permissions for the original logged in
user.

Is this how this is supposed to work? Basically it seems to me that /
dev/stdout is therefore useless inside any shell script, if there is a
chance that someone might want to use it after calling su someday. Is
there a better solution for me? (I can obviously avoid using /dev/
stdout but it's very convenient in some cases). Thanks, and please
advise if this is not the correct group for these kinds of questions.

When I run a binary, how come it knows about what are the default
path. I know that when binary need to search for shared objects at run
time binary sees first LD_LIBARAY_PATH then RPATH then the default
path.

So the question is if LD_LIBARAY_PATH and RPATH aren't set which
component tells the runtime linker to search the library in the /usr/
lib or /lib that is nothing but the fefault path.

Is it set during the compilation phase of the binary? if yes then what
intermediate step of compilation phase does that ?

thanks in advance.
