$$ is expanded by the shell to its own (decimal) process ID (in ASCII). Every active process has an entry in /proc corresponding to its decimal process ID (in ASCII). Each process is reflected in a numeric sub-directory in /proc and among the entries in that directory is a symbolic link called "exe" that references the executable file of the program that is being executed in that process. Voila! Run "ls -lF /proc/$$" to see what other per-process, reflexive goodies are available. Some of the names are suggestive of their meanings.
