Changing argv[0] under Linux.
Quoted 3 lines
Any suggestion on how to get the binary name from the core image?
How about:
exec("/proc/self/exe", ...)
I found something like this handy when writing an self extracting compressed executable a while ago.

Hi Jon :)
Quoted 1 line
exec("/proc/self/exe", ...)
That's good, but I would like to avoid to mount procfs: what if
the mount point '/proc' doesn't exist? If you create it, you must mount root rw and remount ro again, not a very good idea if it haven't been fscked yet, for example. You can mount under /tmp, if it exists at all, but that simply displaces the problem. What if /proc/self/exe is not part form procfs, but from some evil user ;))
Thanks a lot for your answer :)
