Execute ELF binaries from pipes & and terminals. This makes it possible to execute binaries that are not stored in a file system or for which the execute permission is not set and to run binaries directly from stdin; e.g. when piping gcc output or when downloading them via SSH.
It works by allocating an in-memory file via the memfd_create(2) syscall, copying all data from the executable there and finally executing it using the fexecve(3) syscall.
pipe_exec will first try to execute the file in place; e.g.
pexec </bin/ls would not load ls into memory first.
$ cat `which date` | pexec -u

And then compile the code:
makeTo install copy the binaries to /usr/local/bin or execute this command which will perform the copy for you.
sudo make installYou can supply $PREFIX to use a different installation directory; the
default prefix is /usr/local.
